Seed weight per plant on main and secondary spike, oil yield and its percentage, 100 seeds weight per main and secondary spike, biological yield and harvest index were assessed. The results showed that seed and oil yields and most of characteristics were significantly different among castor bean genotypes. Ashtiyan 1 had higher values for most traits except 100 seeds weight per main and secondary spike, length of main stem, oil percentage and harvest index, with respect to other genotypes. Oil percentage, was higher in Shahreza 1 and Ashtiyan 2 genotypes than other genotypes. Low oil yield of Shahreza 1 genotypes was due to low seed yield. But in Ashtiyan 2 genotype high oil percentage amends low seed yield and this genotype like genotype Ashtiyan 1 had preference with respect to other genotypes in oil yield. It seems that Ashtiyan 1, Ashtiyan 2, and Shahreza 2 genotypes are suitble for cultivation in Hadishahr areas. Manuscript profile -

Then advanced winter and intermediate wheat genotypes obtained from this research station were evaluated in two separate experiments under normal irrigation and deficit irrigation after anthesis in a randomized complete block design with three replications. Significant differences were observed among genotypes in terms of grain number in spike. Genotypes No.6 and 10 had the highest amount of this trait (42.2 and 42.6, respectively). 1000 grains weigh decreased significantly under water stress, also the amount that were different significant among genotypes. The highest and lowest grain yields (6093.3 and 4819.4 Kg per hectare) were obtained by normal and water stress conditions, respectively. In terms of grain yield, the genotypes which had gain number per spike and 1000 grains weight in high value in both condition, had better yield in comparison with others. Manuscript profile -

A factorial experiment was arranged in Randomized Complete Blocks Design with four replications. Four sowing date (April 21, May 5, May 21, June 5) and five genotypes (IL-111, S-541, PI-250536, PI-250537, Syprus bregun) were established levels as second factors. Results of analyses of variance showed that the effect of planting date were significantly differenct for traits of grain yield, number of grain per boll, number of bolls per plant, harvest index and oil grain percentage. The grain yield of first, second, third and fourth sowing dates were 223.12, 197.65, 185.71 and 173.99 gr/m2, respectively. The highest fertile boll, kernel per boll and 1000-kernel weight were allocated for PI-250537, S-541 and Syprus bregun genotypes in the first planting date, respectively. Interaction between planting date and genotype on lateral branch, total dry matter, grain yield, number of bolls per plant, number of grain per boll, harvest index, oil percentage and 1000-kernel weight were meaningful (P 0.01). Correlation coefficients between traits showed that there were positive significant differences for number of grain per boll with grain yield. Based on these results, early spring planting date will be move suitable than other dilatory planting. Manuscript profile -

Eggplant seedlings were cultivated in May in a randomized complete block design with three replications. Each replication consisted of four rows of 10 plants. Five leaves were randomly sampled at weekly intervals until October to estimate the incidence and population fluctuation of T. tabaci. The number of thrips was counted on the surface of four square centimeters of leaves using a binocular microscope. All analyses and comparisons were carried out using statistical package SAS. The results showed that there was a significant difference between the number of thrips on upper and lower leaves, so that the number of thrips on lower leaves were several times higher than that of on upper leaves. Borazjan and Juybar-Mazandaran with the mean number of 1.55 and 0.86 had the highest population in 2000 and 2001, respectively. In complex analysis, there was no significant difference between the thrips abundance on lower and upper leaves. Incidence of thrips faced with increase from June, and the maximum number was recorded in early until late July in both years. The results indicated that, a trend of increase initiated from late June in Varamin. Borazjan had more thrips than other genotypes and the thrips abundance in the first year was two times of the second year. Manuscript profile -

This study was conducted on different barley genotypes to identify the genotypes that are resistant to Sunn pest. The study was a randomized complete block design with three replications that was conducted in 2016 and 2017 in Neyshabour Agricultural Research Center. The results showed that the highest number of E. integriceps was recorded in genotype 3 and the lowest number of E. integriceps was related to genotypes 2 and 6. Genotype 13, with the important indices of grain yield under non-stress condition (Yp) and genotype 10, with the important indices of grain yield under stress condition (Ys) in the region, were identified to have high yield potential and low sensitivity to E. integriceps. Yp had a positive and significant correlation with the mean of productivity (MP), geometric mean (GMP), and stress tolerance index (STI). YS had a positive and significant correlation with all indices except stress susceptibility index (SSI) and tolerance index (TOL). Therefore, the MP, GMP, and STI were the only indices that showed a positive and significant correlation with Yp and Ys. In conclusion, based on the results of this study, genotype 20 can be nominated as a E. integriceps-resistant genotype in Neishabour region. Genotype 1 can also be reported as a sensitive genotype to E. integriceps with low yield. Manuscript profile -

To study the genotype and environment interaction and determine the stability and adaptability of grain yield of quinoa genotypes in different regions of Iran, ten genotypes were evaluated in a randomized complete block design with three replications in four regions of Karaj, Shahrekord, Urmia, and Kashmar during 2017-2018 cropping season. The studied genotypes included Titicaca, Red Carina, Giza1, Q12, Q18, Q21, Q22, Q26, Q29, and Q31. The results of the combined analysis of variance showed that the effect of environment and the genotype and environment interaction on the grain yield were significant (p≤0.01). The highest grain yield in Karaj and Shahrekord (717 and 2196 kg.ha-1, respectively) was obtained by the Q26 genotype and in Urmia and Kashmar (1614 and 829 kg.ha-1, respectively) by the Q18 and Titicaca genotypes, respectively. According to the results of stability and compatibility analysis with different methods and indices (parametric and non-parametric), the Red Carina genotype was identified as a genotype with suitable and stable yield and compatible with the study areas, with 996 kg.ha-1 grain yield higher than the average yield of all genotypes (939 kg.ha-1), the highest rank of simultaneous selection index for yield and stability, the lowest mean rank (1.56), and the minimum standard deviation of rank (SD = 1.03).

There exists various accessions of this plant in Iran; however, no comprehensive study to fully understand it has ever been carried out. Twenty populations of fenugreek native to Iran were collected from different parts of the country to asses the genetic variability of the plant and study some of their features. The results suggest that there are significant differences in most of traits under study. The wet weight ranged between 23.93 and 44.41 grams of the wet weight per plant. Moreover, the accessions, were classified with regard to the flowering features into 3 categories of early blooming, inter blooming, and late blooming. The results also showed that the accessions started to produce flower within 39 to 76 days of plantation. The index of one thousand seed weight also showed meaningful differences ranging from a low of 5.56 grams in Semnan mass to a high of 19.44 grams in Kermanshah accession. The analysis of ploid level of the accessions native to Iran revealed that all the masses under study were diploid (2n=2x=16). Finally the results show that the native masses of Iranian Fenugreek enjoy high diversity regarding the features under study and make suitable genetic resource for breeding programs.

Genotypes and varieties were inoculated with of this pathogen artificially in both experiments. After inoculation, disease characteristics such as disease index, area under disease progress curve (AUDPC), percent of dried flower and yield in the field and disease index, percent of infected leaves and surfaces of blight on leaves in greenhouse were recorded. Results of greenhouse experiment showed that varieties and genotypes including Super 2270 King stone, Kallgi and 8403 had the least infection to disease. On the other hand, Imperial variety and 8406 genotype exhibited the highest amount of infection. Varieties in the field experiment, including Super 2270, King stone, Early urbano VF, and 8402 genotype, showed the least infection and genotypes like 8405, 8406, 8407 and Peto early ch variety had the highest amount of infection. In both experiments Super 2270, King stone and Early urbano VF varieties were found resistant to be this pathogen, but 8402 genotype was resistant only in the field and 8403 genotype and Kallgi variety were resistant only under greenhouse condition. Soria variety showed a considerable disease spot in both experiment but could produce the highest means of yield about 91.64 ton/ha. in the field, compared to other varieties and genotypes.

To achieve this goal, ten promising lines of rice along with two improved cultivars (Hashemi and Kadous) were compared at National Rice Research Institute in Rasht, Iran, for three years (2006, 2007 and 2008). The experimental design was randomized complete blocks with four replications in these three years. The combined analysis of variance indicated significant difference among genotypes, for the traits studied. This indicates genetic variation among genotypes understudy. The interaction of genotype × year for yield was significant which demonstrate different responses of genotypes during different years. Different stability analysis methods were used to determine the higher and stable yielding variety like: environmental variance, coefficient of variability, coefficient of regression proposed by Finaly and Wilkinson, Deviation from regression by Eberhart and Russel, Shukla's stability variance, Wricke's equivalence, coefficient of determination of Pintus and non-parametric method of rank. By using these analyses it was found that Hashemi was a stable yielding variety. It was also revealed that line No. 9 (IR78530-45-3-1-3), line No. 6 (IR76993-49-1-1) and 8 (IR78533-30-2-1) were found as stable producer lines. Manuscript profile -

MoreIn a field experiment, the effect of drought stress on yield and yield components of three wheat genotypes was investigated during 2013-2014 in Parsabad, Iran. It was performed in a split plot expriment based on randomized complete block design with three replications. The experimental factors consisted of irrigation regimes at five levels which considered as main factor and genotypes at three levels (Shirodi, Chamran and line N-80-18) as sub factor. Results revealed that the effects of irrigation regimes were significant on seed yield, plant dry weight, plant height, leaf area index, number of spike per m2, number of seeds per spike, 1000 seeds weight and seed protein content. The effect of genotype on all of the traits under study was significant. The effects genotype × irrigation regime interaction were also significant on seed yield, dry plant weight and number of seeds per spike. Under optimal irrigation, seed yield of Shirodi and Chamran cultivars and line N-80-18 were 4661.7, 4200 and 4402 kg ha-1, respectively. Moisture stress significantly reduced seed yield and yield components. Deficit irrigation increased seed protein content of the genotypes under study. Chamran cultivar produced highest seed yield under drought stress and in rainfed conditions, while its grain yield was reduced by 26% as compared with that of optimal irrigation condition. Based on the stability of yield of this cultivar in the all of irrigation regimes, under water limited condition, it can be considered suitable for this region. Manuscript profile -

To investigate the effect of water deficit stress on yield and components of some red bean genotypes a split plot experiment in the form of randomized complete block design with three replications was carried out at the Agricultural Research Station of Islamic Azad University, Arak Branch. The treatments consisted of full irrigation (control), cutting irrigation off during flowering stage, cutting irrigation off of pod filling stage and three genotypes of red bean (derakhshan, goli, and D81083). The results showed that the effect of cutting off irrigation during the growth stages on biological yield, grain yield, harvest index, number of pods per plant, number of seeds per pod was significant. The results also showed that the highest seed yield belonged to the full irrigation (control) treatment, where D81083 and goli produced higher yields than derakhshan. Highest grain yield was belonged to goli at full irrigation (control) treatment. Among the genotypes under study, D81083 had the lowest amount of reduction equal to 60 percent during cutting off irrigation at flowering stage. Number of seeds per pod decreased when irrigation was cutted off during the flowering stage. Derakhshan produced higher yield than the other genotypes and its seed per pod decreased by 38 percent. The results also revealed that red bean genotypes were very sensitive to deficite water stress. As a whole D81083 and goli genotypes were higher yielders than Derakhshan under limited water conditions. Manuscript profile -

To study the stability of yield and yield components of seven promising lines of mungbean as well as the check (Parto), three experiments were conducted in an RCBD with three replications in three regions of the country, i. e. Khuzestan (Agricultural and Natural Resources Research and Education Center of Safi Abad, Dezful), Golestan (Agricultural Experiment Station of Gonbad) and Fars (Agricultural Research Station of Zarghan) in 2014-2015 for two years. Each plot consisted of four four-meter-long rows. The traits studied were: the number of branches per plant, pods per plant, seeds per pod, 100-seed weight, plant length, and seed yield. A combined analysis of variance was performed. Because of the significant genotype by environment interaction and, as a result, the different responses of genotypes to various environments, stability indices were calculated to determine the stability of genotypes. To do this, Romer's environment variance, Francis and Kannenberg's environmental CV, and the regression coefficient of Finley and Wilkinson were determined. AMMI analysis was also performed. Based on Francis and Kannenberg's environmental CV and coefficient of Finley and Wilkinson genotypes VC6368 (46-40-4) and VC6371-94, and VC6469 and VC3960 were stable, respectively. Based on the CV of intra-location, VC3960-88 and VC6368 (46-40-4) were stable. According to stability analysis results and considering seed yield, seed weight and other suitable characters, genotypes VC6371, VC6368 (46-40-4) and VC3960-88 were selected for further studies.

To identify rice genotypes tolerant and sensitive to drought stress during flowering 15 genotypes were studied under two environments (stressed and non–stressed conditions) in a randomized complete block design with three replications at Abbas Abad and Katalom regions during 2018 growing season. To evaluate the susceptibility or tolerance of genotypes to drought stress, traits like yield under non-stress (Yp) and drought stress (Ys) and average yield of all genotypes under stress and nonstress (Ȳs), stress tolerance indicators, arithmetic mean (MP), geometric mean (GMP), harmonic mean (HM), tolerance (TOL), stress tolerance (STI), yield index (YSI), yield index (YI) and sensitivity to stress (SSI) were evaluated. Among the genotypes under study, sixty (54.62) and Ali Kazemi (46.92) showed the highest values for HM index. Shastack based on MP and GMP, shastack (61.04) and Tarom genotype (3.15) and STI index with similar trend to shastack (1.54) and Ali Kazemi (1.08) genotypes, respectively. Stress sensitivity (SSI) and yield stability index (YSI) values were similar for both genotypes of Shirudi (0.32) and Caspian (0.76). Cluster analysis based on 10 indices under drought stress resulted in two groups. Based on the results of principal component analysis, the first two components accounted for more than 92.6% of total information. The first component explained 58.76% of the total variation. According to the drought tolerance index of Shastak, Ali Kazemi and Sang Tarom genotypes are recommended as tolerant genotypes having the highest yield in both environmental conditions and having high stress tolerance index.

Treatments consisted of water deficit in three levels (85%, 60% and 35% of field capacity) and five wheat genotypes (Mihan, C-88D-7, C-88D-17, C88D-19 and C88D-20). Results showed that increasing water deficit resulted in reduced amount of potassium, whereas, elements like sodium, phosphorus, proline and soluble sugar were significantly increased. Drought stress, however, reduced the total protein content in C-88D-19, C-88D-17 and C-88D-20 genotypes and, calcium content in ‘Mihan’ and C-88D-19. In the mean time, protein and calcium contents increased in other genotypes in such a way that total protein content of ‘Mihan’ and C-88D-7 and, calcium content of C-88D-20, C-88D- 17 and C-88D-7 were increased with increasing drought stress. Since C-88D-20 showed lowest proline and soluble sugar accumulation and biomass production than other genotypes it would be considered as a sensitive genotype to water stress as compared to the other genotypes.

Three durum wheat genotypes (SAJI, BCR and STJ) with three sowing dates, prior to effective rainfall (the amount and time of effective rainfall were 33.2 and 34.5 mm, and 26 October, and 5 November for two years of experiment, respectively). 15 days after effective rainfall and 30 days after effective rainfall were evaluated for four densities of 250, 350, 450 and 550 plant per square meter. Traits like number of spikes per square meter, 1000 kernel weight, seed and biological yield, harvest index and absorbed radiation percentage were measured. The results of mean comparisons of simple effects showed that the number of spikes per square meter in the planting date before rainfall was more effective than two other planting dates. Biological yield and absorbed radiation percentage were 26.9 and 12.9 percent higher respectively in second year of experiment as compared to the first year. Comparison of interactions means showed that STJ genotype under 250 seeding density and 15 days sowing date after effective rainfall, produced highest 1000 kernel weight, while SAJI cultivar at 550 seeding density and planting date before effective rainfall showed the highest kernel yield. The SAJI cultivar showed highest biological yield under 450 seeding density and planting date before effective rainfall. For all three genotypes, the highest percentage of radiation absorption was observed when sowing date used before rainy season using 450 and 550 seeding densities. In this study all genotypes showed the highest traits values at first planting date and under 450 seeding density. The highest values of protein and chlorophyll content were observed using 350 seeding density. Manuscript profile -

The main purpose of this study was to achieve high yielding durum wheat genotypes with higher yield stability in different environmental conditions, tolerance to environmental stresses such as cold damage, terminal drought, and heat stresses. Hence, 16 durum wheat lines were evaluated for grain yield stability and morphological traits in Maragheh, Sararood, Qamloo, Ardabil and Urmia Agricultural Research Stations in 2012-15. In each location, the experiments were conducted in a randomized complete block design with three replications. Based on combined ANOVA, there were significant differences among the environments (E), genotypes (G) and G×E. GGE-biplot analysis showed that the 14 environments belonged to 3 mega-environments, and different genotypes had higher yield in each mega-environments. The AMMI and GGE results also confirmed that genotypes 2 (G-1252) and 3 (61-130/414-44//…) were the most high-yielding durum lines with reasonable yield stability across environments. Also, genotype 10 was the most adapted genotype to Ardabil. Line 61-130/414-44//… had 60, 11, 31, 10 and 17% more yield than check line (Saji) in Maragheh, Sararood, Qamloo, Ardabil and Urmia under rainfed conditions, respectively. Hence, these lines can be candiates to release as new durum varieties for cold and moderate rainfed areas. Complementary irrigation could increase grain yield up to 14 and 68% in Maragheh and Sararood, respectively. It can be concluded that finding new stable high-yielding durum lines, with better performances, as compared to the existed varieties, is a great progress in durum breeding programs in cold rainfed areas. Moreover, the GGE biplot and AMMI analysis had good performance in adaptability and yield stability analysis in durum genotypes and could be used to evaluate durum genotypes at different locations over the years in durum breeding programs.

This study aims to evaluate the root and shoot structure of quinoa cultivars in response to the application of phosphorus and zinc in the Research, Agricultural Education and Natural Resources Center of Khuzestan province in a factorial design with three factors including the use of triple superphosphate fertilizer at four levels (0, 6, 12, 18 mg.kg-1 soil weight), foliar application of zinc sulfate in three amounts (water without zinc sulfate (control), foliar application at 4 and 8 per thousand concentrations) and three quinoa cultivars (Giza 1, Q26, Titicaca) were performed in pot and in three replications. The results showed that root parameters such as root dry weight, root width, root diameter, distance from the first branch to the tip root, and the weight ratio of root to shoot were affected by phosphorus fertilizer levels and quinoa cultivars (P≤0.01) and foliar application of zinc sulfate had a significant effect only on root dry weight, root width, distance from the first branch to the root tip, root density, root weight to shoot weight, and aerial part parameters. Q26 cultivar was identified as the best cultivar in terms of root structure development, which at 18 mg.kg-1 phosphorus levels and 4 per thousand zinc sulfate concentration had a maximum root dry weight (3.23 g.plant-1), root width (18.06 cm) and distance from the first branch to the root tip (53.23). At these levels of element consumption, the highest number of grains per plant (4542) were obtained in cultivar Q26. Based on the experiment results, the optimal level of elements by reducing antagonistic effects and increasing synergistic effects of P and ZnSO4 led to the root structure development, improved element uptake and increased production components of quinoa cultivars.

The experimental treatments were: drought stress at 2 levels (control or irrigation at 90% of field capacity and irrigation at 70% of field capacity), foliar application of nano iron chelate at 2 levels (control and 2 mg/l) and 13 genotypes of chamomile consisting at: Isfahan, Mashhad, Shiraz, Kerman, Arak, Ardestan, Gachsaran, Nain, Khozestan, Safashahr, Kazeroon, Germany and Hungary. The results showed that besides the main effects of stress×genotype, the genotype×nano iron chelated and stress×nano iron chelated interactions and the triple effects were also became significant. Mean comparisons showed that the condition of genotypes at any level of stress and nano iron chelated had different trends. Using nano iron chelated in drought stress decreased chlorophyll a in Shiraz, Khozestan, Nain, Hungary and Germany genotypes, decreased chlorophyll b in genotypes of Isfahan, Kazeroon, Ardestan, Khozestan, Nain and Germany, decreased total chlorophyll in genotypes of Isfahan, Shiraz, Ardestan, Khozestan, Nain, Hungary and Germany and decreased anthocyanin content in Isfahan, Shiraz, Safashahr, Kazeroon, Khozestan and Germany genotypes. Using nano iron chelated in drought stress also caused a decrease in flower yield of Mashhad, Arak and Nain and a decrease per plant yield of Isfahan, Mashhad, Arak, Safashahr, Khozestan and Nain genotypes. The highest per plant yield (0.665 g.) belonged to Kerman genotype, were achieved through non-stress and use of nano iron chelate treatments and the lowest per plant yield (0.164 g.) to Arak genotype through the stress and non-spray treatments. Totally the interaction of chamomile genotypes to drought stress were different. Among the genotypes under study the Shiraz genotype were more resistant to stress compared to others. The effects of application of nano iron chelated were different depending on the genotype and for most of the genotypes it increased the photosynthetic pigment contents and yield components of Chamomile. This shows the effectiveness of low rate application of nano iron chelate. Manuscript profile -

Evaluation of the parents, F1 and F2 generations was carried out at the Gonbad Kavous University at 2017. 50 plants of both the F1 population and the parents and 350 individuals of the F2 population were grown in an experimental field with a spacing of 25 cm × 25 cm. Chlorophyll fluorescence properties Fo, F'o, Fm, F'm, F ', ETR, Fv, Fv / Fm, F'v / F'm, NPQ, qP, Y (II), qN, qL and weight of 100 grains, tiller number, filled grains number, unfilled grains number, plant height, panicle length, stem diameter, grain length, width and shape, straw weight, grain filling period, flag leaf length and width were recorded. The rate of electron transfer through photosystem II, flag leaf width, base fluoresce in dark-adapted conditions, the number of fertile tillers, maximum fluorescence in the dark-adapted conditions, number of primary branches, flag leaf area, flag leaf length, main panicle length and plant weight had the highest effect on grain yield, respectively. The highest response to selection belongs to 9th economic weight (heritability) in both BLPSI and LPSI indices. After, sixth coefficients (correlation) had the highest response to the selection. The results showed that the inheritance of Chlorophyll fluorescence parameters can be effectively used as an economic weight in the selection of the best individual. Genotypes 3, 6, 17, 24 and 30 were selected based on LPSI and genotypes 3 and 6 based on BLPSI as superior genotypes. The BLPSI and LPSI indices had high efficiency in this research and are recommended for improving the rice grain yield. Manuscript profile -

Meanwhile, in some pomegranate orchards, salinity stress is one of the abiotic stresses that harm agricultural crops such as pomegranate production by reducing productivity. This research aims to compare growth characteristics between selected genotypes including 1- Chah Afzal 2- Vahshi Babolsar, 3- Narak Lasjerd Semnan 4- Poost Siahe Yazd, 5- Malase Yazdi, 6- Rababe Neyriz, under salinity stress, in a randomized complete block design with three replicaions at Chah Afzal research station of Ardakan city. During the whole experiment, the trees were irrigated with saline water with salinity of 9 ± 0.5 dS/m every 12 days. Based on the results of this research and considering the lowest amount of ion leakage, the highest content of relative humidity and potassium, the high amount of total chlorophyll, carotenoid and leaf surface ratio, the lowest sodium to potassium ratio and necrosis percentage Chah Afzal genotype showed very good resistance to salinity conditions, followed by Poost Siahe Yazd, Vahshi Babolsar, Narak Lasjerd, Malase Yazdi and finally Rababe Neyriz were highly sensitive to salinity. According to the results of cluster analysis, the highest similarity between genotypes based on the parameters mentioned above was between the Narak Lasjerd and Malase Yazdi. The highest difference between Chah Afzal genotype and other genotypes was registered. This shows a significant difference in the superiority of Chah Afzal genotype over other genotypes in total traits. Therefore, due to the compatibility and proper growth of these genotypes in saline conditions, it is suggested that they could be used as a rootstock and the cvs. Malase Yazdi and Rababe Neyriz, which also produced flowers and fruits in saline conditions, can be grafted on them.

It has wide biodiversity of halophile and halotolerant microorganisms. In this study, members of the genus Halomonas including moderate halophiles bacteria were isolated from Urmia Lake and their phenotypic and genotypic properties were studied. Samples were collected from different sites of Urmia Lake and were transferred to the laboratory under sterile condition. Then Alkaline Peptone Water (APW), Nutrient Broth (NB), Nutrient Agar (NA), MacConkey Agar (MAC) supplemented with 5% and 10% salt were used for isolations. These cultures were incubated at 35-37 ˚C for 48h and repeated cultures were performed for achievement of pure cultures. Finally 80 isolates were produced. These isolates based on morphological characteristics and phenotypic surveyswere studied. Also biochemical, characterization and salinity tolerant tests were carried out on the isolated strains.For genotypic and phylogenetic studies, 15 isolates were selected for genetic experiment based on 16S rRNA gene sequence. Therefore genomic DNA of selective bacteria was extracted and was amplified by PCR technique. The results of sequencing 16S rRNA were edited by dependent softwares and sequences similarity of these strains were analyzed on comparison with registered strains in Gen-Bank of EzTaxon database. 6 isolates belonged to Halomonas sp. that phylogenetic tree was constructed by the neighbor-joining method. From the phylogenetic viewpoint, these strains belonged to Halomonas janggokensis, Halomonas gomseomensis, Halomonas boliviensis and Halomonas andesensis species. Sequence similarities of Halomonas janggokensis and Halomonas gomseomensis were more than 99%. Sequence similarities for Halomonas boliviensis and the half of isolated Halomonas andesensis showed between 97% and 98.9%. The half of other Halomonas andesensis indicated 94.2% .

The three local strains of Taliqan, Lorestan, and Shiraz have been used for many years in preparation of the only commercially available killed vaccine against agalaxy in the Iranian market. This study was conducted to determine the genetic link between these strains. Materials & Methods: All three strains of Taleghan, Lorestan, and Shiraz were cultivated freshly on PPLO agar media. The genetic material was extracted by boiling method. In order to investigate the genomic relations between these strains, a Multi-Locus Variable Number Tandem Repeat Analysis (MLVA) strategy concentrating on 4 VNTR loci of 5, 9, 17, and 19 was employed. The nucleotide sequences of all PCR products were determined, as well. Results: Nucleotide sequence analysis showed an identical MLVA pattern by all the three strains. When compared to the Mycoplasma agalactiae PG2 laboratory strain, the only VNTR19 locus was different between Iranians and the PG2 strain, with respect to a 3bps addition at this locus in Iranian strain. Conclusion: The identical genetic pattern of the three Iranian strains is likely an indication of the activity of one or more indigenous ancestral clone in the geography of Iran that has been appeared and evolved throughout its livestock history and became homogeneous and predominant due to the absence of efficient disease control policies. The similarity between three Iranian and the PG2 strains might be due to homoplasy or human intervention through animal husbandry activities such as livestock importation. Applying standard genotyping methods to a larger number of local isolates help to better assess this observation. Manuscript profile -

Genomic DNA extracted from the samples using the amplification was reproduced and products using polyacrylamide gel were electrophoresed. A total of 97 bands were scored for marker ISSR, 78 bands were polymorphic bands of 80.22 percent. The highest and the lowest percentage of polymorphic were ISSR-8 primers with 90% and polymorphic ISSR-5 with 73% band, respectively. The average value of PIC was 0.18 in this test. The most of the PIC was reported by primer ISSR-6 and ISSR-8 with 0.27 and the lowest primer was also reported by ISSR-1 with 0.12. Based on the study, dendrogram of cluster resulted from the analysis of UPGMA method with simple matching coefficient; the cultivars were classified into five main groups. In this study, Pomelo was in a separate cluster. The ISSR molecular marker of Satsuma mandarin and clementine Suji Yama were grouped into two distinct groups. Therefore, this molecular marker presents the different levels of diversity at the genome level which can be useful in germplasm management and hereditary stocks.

Experiments were carried out at Rudasht saline Research Station in Isfahan during 2013, 2014 and 2015. In the first year, two cotton mutant genotypes and two commercial cultivars as control were selected for the second and third years. The second year experiment was split factorial based on randomized complete block design with four replications. In this experiment, the main plots consisted of irrigation with 4 (control), 8 and 12 dS / m saline water and subplots including factorial combining of three genotypes (mutant genotype 1673, LM 1303 and Shayan) with spraying three levels of potassium sulfate (2, 4 and 6 kg / 1000 liters of water per hectare and water). The results showed that salinity of irrigated water reduced linter percentage, yield and harvest index. Among the cultivars, the highest linter percentage and its yield were observed in the LM 1303 genotype. Spraying with potassium sulfate had a positive effect on these traits and increased cotton genotypes yield under salinity conditions. The results of this study showed that in saline conditions, soluble potassium sulfate was used to reduce the effects of salinity and increase the yield of cotton genotypes.

With the aim of evaluation of genotypic variation for Fe efficiecny, 121 barley genotypes during the growing season of 2015-2016, a research farm was carried out at the agricultural research institute of the dryland (Maragheh) were studied under rainfed field conditions. . The experiment was conducted in square lattice. Based on ANOVA, there was significant differences among genotypes for seed Fe concentartion and content traits. The high range of variation for these traits showed that there is a great genotypic variation among barley genotypes. The existance of high general heritability (h2) for seed Fe concentration and content could be helpful in breeding for these traits under different environments. Seed Fe concentration had significant and positive correlation (r=0.63**) with seed Fe content. In short, the result of this study revealed the great genotypic variation among barley genotypes for Fe absorption and accumulation in seed. Moreover, the efficient genotypes could alleviate drought stress that will result in higher grain yield with Fe-dense grains under cold dryland conditions. Manuscript profile -

For this purpose, 29 inactive women aged 30 to 45 were randomly selected from volunteer women in Shahriar, Tehran Province. The Subjects did 8 weeks of aerobic training in 5 sessions per week and each session lasted 30 minutes with an intensity of 55 to 75% of reserve heart rate. In the first two weeks, they trained with 55-65% of the maximum heart rate, and in the second two weeks with 60-65% of the maximum heart rate, and in the last 4 weeks with 65-75% of the maximum heart rate. 10 minutes for warming up and 10 minutes for cooling down were considered in each training session. Bruce's seven-step test was used to determine the VO2max before and after the exercises. The test started with a slope equal to 10% and a speed of 2.7 km/min on the treadmill, and each stage was completed in three minutes, so that in the seventh stage, the slope was 22% and the speed was 9.6. Then, among the subjects who were able to perform the desired test based on the researcher's expectation, saliva sampling was done for DNA sequencing to determine the genotypes. The RFLP method was used to determine the gene genotype. Enzymatic digestion at 65 degrees Celsius overnight, including one microliter of enzyme, 3 microliters of PCR product, 2 microliters of special buffer and 15 microliters of deionized water was used. The results of data analysis were analyzed using the dependent t test. The results showed that VO2max in women with AT genotype was not significant before and after exercise intervention (p = 0.840). The amount of VO2max in women with AT genotype was not significant on average before and after exercise intervention (p = 0.633). Also, the amount of VO2max in women with AT genotype, after exercise intervention, was not significant compared to TT genotype. In this research, it was shown that the significant improvement of Vo2max did not depend on their genotypic differences, and between AT and TT genotypes, the rs1870377 polymorphism of the VEGFR gene and the changes in aerobic performance of obese untrained women after eight weeks of aerobic training no significant relationship was observed.

This research was conducted in order to investigate the allelic and genotypic polymorphisms of the gene locus involved in heat stress (HSP90β) in native chickens of Mazandaran, West Azerbaijan and commercial broiler and egg-laying chicken populations using PCR-RFLP technique. Randomly, blood was taken from 400 chicken and genomic DNA was extracted by salting out method. The desired gene locus of 494 base pairs was amplified with the help of specific primers and MspI enzyme digestion was used to identify the mutation in the gene locus. For this gene locus, two types of genotypes M1M1 and M1M2 and two alleles M1 (with one band of 494 bp) and M2 (with two bands of 248 bp and 246 bp) were identified. Mazandaran, West Azerbaijan native and commercial broiler chicken masses were in the Hardy-Weinberg equilibrium. For Mazandaran, West Azerbaijan native and commercial broiler chicken populations, Shannon information index was 0.32, 0.28 and 0.40, respectively, the fixation index was 0.12, -0.11 and -0.16, respectively and the observed heterozygosity was 0.19, 0.17 and 0.28, respectively. Due to the presence of polymorphism and mutation in this gene locus, it is possible to use this marker in the native chickens of Mazandaran and West Azerbaijan with genetic selection and in commercial broiler chickens with genetic selection at the line level, to remove heat-sensitive chickens and keep them heat-resistant chickens are used.

In order to investigate the effect of salinity on germination and seedling growth of cowpea (Vigna unguiculata), an experiment was conducted as factorial based on completely randomized design with 4 replications. The study was carried out June 2013 at the genetic and gene nation bank laboratory of Seed and Plant Improvement Institute, Karaj, Iran. Treatments were including of 4 levels of salinity (0, 50, 100 and 150 mM), 15 genotypes of cowpea (mashhad, omid bakhsh1, omid bakhsh 2, 001, 002, 7245, 7254, 7262, 7288, 7244, 7256, 7291, 7289, 7278 and 7305). The results showed that the effects of genotypes and salinity levels on different measured traits were significant at 5% probability level. Germination under saline conditions gave significant reductions for each treatment tested. The interaction effects of genotype and salinity, cultivar Mashhad in 150 mM NaCl salinity had the highest final germination percentage (84 %) and vigor germination (8.1). Also, the highest and lowest germination rate in high salinity (150 mM NaCl) had obtained in 7291 (5.3 seed per dar) and omid bakhsh 2 (3.7 seed per dar) cultivar, respectively. Increasing NaCl applications generally decreased the fresh and dry weight of Plumule and fresh and dry weight radicle. In high salinity level (150 mM NaCl), the highest of fresh and dry weight of Plumule had obtained in cultivar Mashhad (0.76 and 0.995 gr). Decrease in Plumule and radicle weight by NaCl application is due to increase in osmotic pressure of soil and decrease in availability of soil water because of NaCl Genotypes mashhad and 001 in NaCl salinity were evaluated as the most resistant and susceptible genotypes, respectively. Based on the results of this experiment, there is necessary genetic diversity among the Cowpea genotypes of Iran for selection of salinity resistant cultivars. Manuscript profile -

majid taherian hamid tajala hamidreza nikkhah The objective of this study was to evaluate genotypes (G), environments (E) and toanalyze genotype by environment (GE) interactions on the seed yield of 20 barleypromising lines by the additive main effects and multiplicative interaction(AMMI) model.The trials wer More The objective of this study was to evaluate genotypes (G), environments (E) and toanalyze genotype by environment (GE) interactions on the seed yield of 20 barleypromising lines by the additive main effects and multiplicative interaction(AMMI) model.The trials were conducted at two research stations (Neyshabur and Torogh Mashhad) fortwo successive years (2015-2017). The result’s of AMMI analysis for seed yield indicatedthat the Genotype main effects, environment, and GE interactions as well as two firstinteraction principal components (IPCA1-2) were significant. AMMI biplot was able todistinguish stable genotypes and environments with high and low genotype discriminationability. The genotypes 1 and 10 with higher mean yield than total mean were to be moststable genotypes, while the genotype 19 and 2 with the highest contribution to GEinteraction, were to be the most instable. The result of recommended genotypes based onAMMI analysis showed that the genotypes 18, 9 and 1 were highly adapted to Mashhadand genotype 20 was adapted to Neishabour environments during this study.

96 - Evaluation of end season drought stress tolerance indices to identify tolerant genotypes of faba bean (Vicia faba L.)
Fateme SHeikh Faramarz Seyedi Drought stress has reduced the yield and cultivated area of faba bean in many regions of Iran. So,in order to identify the best drought stress tolerance indices and select drought tolerant genotypes,24 genotypes of faba bean from ICARDA (International Center for A More Drought stress has reduced the yield and cultivated area of faba bean in many regions of Iran. So,in order to identify the best drought stress tolerance indices and select drought tolerant genotypes,24 genotypes of faba bean from ICARDA (International Center for Agricultural Research in DryAreas) drought resistance nursery and control cultivar (Barekat) were planted in two separateexperiments at Gorgan and Gonbad agricultural and natural resources research stations (GolestanAgricultural and Natural Resources Research and Education Center). Faba bean genotypes wereevaluated in a simple lattice design with two replications in 2015-2016. To determine droughttolerant genotypes, it is necessary to grow them under both stress and non-stress condition. To thisend, various stress tolerance indices such as tolerance (TOL), Stress Sensitivity Index (SSI), MeanProductivity (MP), Stress Tolerance Idex (STI), Geometric Man Poductivity (GMP), Yield Index(YI), Modified Stress Tolerance Index (K1STI) were calculated based on the genotypes in stressedyield in stress and non-stressed conditions. Multiple variance analysis of data showed that therewas a significant difference between the genotypes. In medium stress conditions (SI = 0.46), therewas a correlation between bean pod yield in stress and non-stress conditions, which indicates theability to generalize the yield results in non-stress to moderate drought stress conditions. MP,GMP, STI, HM, YI and K1STI indices can be used to identify tolerant genotypes due to theirpositive and significant correlation with yield in both stress and non-stress conditions. Therefore,1, 3, 12, 19, 20, 21, 22, 23 and 24 genotypes were selected for further investigations in thecrossbreeding program of drought resistance. Manuscript profile -

97 - Growth Evaluative Stimulation of Sugar beet Genotypes under Moderate Saline Stress
كوروش ناظم tooraj mir-mahmoodiTo study the growth stimulation of sugar beet ( Beta Vulgaris L. )under mild salinity, a field study was conducted in Agricultural Research Center in Miandoab in combined analysis design with three replications during the crop year of 2013 in two separated norma MoreTo study the growth stimulation of sugar beet ( Beta Vulgaris L. )under mild salinity, a field study was conducted in Agricultural Research Center in Miandoab in combined analysis design with three replications during the crop year of 2013 in two separated normal and mild salinity ( Ec = 4-5-ds/m ). Combined analyses of variance showed that genotype in environment interaction was statistically significant on sugar content, sugar yield, extraction of sugar coefficient and white sugar yield. Interactions of genotype in specific conditions had significant effect on sugar percentage, sugar yield, coefficient of sugar extraction and white sugar yield. In this research, mild salinity condition induced sugar beet growth and increased traits such as root yield, sugar content, molasses of sugar, white sugar content, sugar yield. The mild salinity also increased it up to 10.5% and 20% compared with normal conditions. Genotypes of 14, 15 and 16 respectively, by Origen 004, 005 and Isela, in average conditions of 9.04, 10.34, 10.81 in normal condition and 16.59, 16.37 and 11.93 ton/ha in stress condition showed the highest sugar yield and were identified as the most suitable genotypes in both situations. In both normal and mild saline conditions between root yield, sugar content, sugar yield and its extraction a positive and significant correlation were observed. The results of factor analysis showed that in normal conditions, there were four factors of 92.5 percent and in mild salinity three factors of 87.80 percent which justified the total variation in root and sugar yield.
