Tomatoes have many varieties that differ in traits of plant growth, quality and shape of the fruit and other traits. In order to investigate the morphological variation of some tomato cultivars in Khash region, an experiment was conducted as a randomized complete block design with three replications and ten cultivars including Orabana, Red Claude, Red Top, Red Jerez, Western Red, Sunsild, Rio Grande, Delba F1, Tivi F1 and blankets Pride. At the end of the experiment traits such as number of fruits per plant, average fruit weight, fruit diameter, final yield, biomass, harvest index, fruit juice volume, fruit dry weight, total soluble solids, acidity and vitamin C were evaluated as agronomic traits. Were affected. At the end of the experiment, after multiple analyzes, it was found that Tivi F1 and Delba F1 hybrids and Orabana had the highest yield and were suitable for cultivation in Khash region. Also, cluster analysis showed that among the 10 varieties of 3 varieties in group A, 5 varieties in group B and 2 in group C were placed. This grouping showed that genetic diversity followed a significant pattern, because cultivars with better and more closely related conditions under conditions were similar in the same groups. Based on stepwise regression results, the number of fruits per plant justified 63.09% of the fruit yield per plant changes. After fruit number per plant, average fruit weight and number of days to flowering had the greatest effect on fruit yield per plant. Manuscript profile

To obtain superior genotypes from 30 advanced spring bread wheat cultivars a field experiment in RCBD was carried out in 1388. Traits like yield, yield components, harvest index, peduncle length, awn length, number of leaf, plant height, flag leaf area, penultimate leaf area, days to booting, days to spike emergence, days to flowering and physiological maturity were recorded. Analysis of variance showed significant difference among genotypes for the traits measured at %1 probability level. This indicates considerable genetic variations among the lines evaluated. Cluster analysis of traits measured, grouped lines into three categories. Eight lines were located in third cluster with respect to some traits including grain yield and other important traits like biological yield, number of seed per spike, spike length, peduncle length, plant height, flag leaf area, and number of spike per m² were found to be superior. By using factor analysis, five factors determined 78.99% of total variation. In this analysis, the first factor could account for 35% of total variation and nominated as effective factor on grain yield. Line with accession number of N-75-5 was found to be highest yielding (289.5 g/m2 (as compared with the other lines. Manuscript profile

In order to identify cold tolerant cultivars of rapeseed (Brassica napus L.) using stress tolerance indices under the influence of humic acid application, an experiment was conducted as factorial split plot based on randomized complete block design with three replications in 2017 and 2018 at Seed and Plant Improvement Research Institute, Karaj, Iran. Factorial combination of cold stress as planting date factor in two levels including 20 October and 20 November, and humic acid factor in two levels including non-application (foliar spraying with pure water) and application (foliar spraying with a concentration of 1.5 per mil at 4-6-leaf stage) were assigned to the main plots and the cultivars were allocated to the sup-plots. The results showed that rapeseed cultivars differed significantly. Based on the results of means comparison, the cultivar WRL-95-07 showed higher yield in both stress and non-stress environments as well as the application and non-application of humic acid than the other cultivars. The correlation of drought tolerance indices with grain yield under stress and non-stress conditions was used to determine the most suitable indices. Arithmetic mean productivity (MP), geometric mean productivity (GMP), harmonic mean (HARM) and stress tolerance index (STI) had the highest significant correlation with yield under normal and stress conditions. Principal component analysis differentiated indices introducing tolerant cultivars and indices introducing susceptible cultivars, and on this basis, the 10 rapeseed cultivars were divided into three groups using cluster analysis. Finally, WRL-95-07 cultivar performed well under stress and non-stress conditions with the use of humic acid, followed by WRL-95-12 cultivar which displayed better performance than the other cultivars under stress conditions when treated with humic acid.

In this study, a total 15 potato (Solanum tuberosum L.) genotypes (11 potato hybrid clones and four control varieties including Caesar, Luca, Savalan and Agria), were evaluated during two cropping seasons in three different locations of Iran, including Ardabil, Hamadan and Karaj, using a randomized complete block design with three replications. During growth period and after harvesting, some of the characteristics like plant height, main stem number, tuber weight per plant, tuber number per plant, marketable tuber yield and tuber dry matter percent were measured. The combined analysis of variance indicated that the effect of genotype on all of the traits under study was highly significant (p < 0.01). The interaction effect for year×location (Y×L) was significant for all traits under study except for tuber number per plant. The interaction effect for genotype×year (G×Y) was significant for all traits under study except for main stem number per plant and tuber dry matter percent. The interaction effect for genotype×location (G×L) was highly significant for all studied traits (p < 0.01). The interaction effect for genotype×location×year (G×L×Y) was highly significant for tuber number per plant and plant height (p < 0.01). Cluster analysis divided 15 genotypes into three clusters. The first cluster consisted of hybrids G1 (clone 16-75), G3, (clone 15-75), G5 (clone 13-75) and G7 (clone 23-75). These hybrids had higher average marketable tuber yield, tuber weight per plant, tuber number per plant, tuber average weight, plant height and tuber dry matter percent as compared to the remaining genotypes. Based on “which-won-where” view of the GGL biplot, G5 (clone 13-75) was desirable in environments HN (Hamadan), and KJ (Karaj), whereas G1 (clone 16-75) and G8 (Savalan) were favorable in environment AL (Ardabil). According to results, hybrids G5 (clone 13-75), G7 (clone 23-75) and G1 (clone 16-75) were near to the ideal genotype and could be regarded as desirable genotypes. Manuscript profile

The present research was done to evaluate the response of seed and oil yields and its components of some rapeseed genotypes at saline areas of Tabriz plain and to select promising lines. The experiment was carried out at the Khosroshah Station of East Azarbaijan Agriculture and Natural Resources Research and Education Center with saline soil (EC of soil and water were 6.7 and 3.2 dS m-1 respectively), during cropping season of 2017-18. The experiment was conducted as randomized complete blocks design with 38 rapeseed genotypes and three replications. Among the genotypes under study significant differences were observed in plant height, seed yield and its components, oil percent, seed and oil yields. The results indicated that WRL-96-01 produced highest silique number per plant (123), seed number per silique (30.3), 1000 seeds weight (3.4 g), seed (3268 kg.ha-1) and oil (1526 kg.ha-1) yields respectively. Comnly used varieties in the area like Okapi and Nima produced lower seed and oil yields under this experiment conditions. Significant and positive correlations were seen among the seed yield and its components, oil yields and also between oil yield with oil percent and seed yield. These results indicate that genotyps under study produced proper seed and oil yields under saline condition. By cluster analysis with ward method, 20 genotypes with higher seed and oil yields, located in one group as promising lines. It seems that these genotypes could be used for future evaluation in saline areas of Tabriz plain and areas with similar climate. Manuscript profile

In order to investigate drought tolerance indices of 14 maize hybrids to different levels of water deficit, a split-plot experiment was conducted in complete randomized block design with four replications at the Agricultural Research Station, University of Tabriz. The main plots consisted of three levels of irrigation regimes (control, mild and severe water deficit) and sub-plots of 14 corn hybrids. Drought tolerance indices were calculated for the grain yields produced. Under mild drought condition, hybrids like SC702, SC500 and K3647×K18 were tolerant based on tolerance index (TOL) and stress susceptibility index (SSI) indices while hybrid SC 500 was the most tolerance one. Based on stress tolerance index (STI), mean productivity (MP) and geometric mean productivity (GMP) indices under both mild and severe stress conditions hybrids K166×K18, SC500، K3647×K18 and SC400 were found to be the most tolerant to water deficit than others. The STI and GMP indices that had highest positive correlation with grain yield under both of these stress conditions. Thus these two indices were determined as the best indices for selection of tolerant hybrids. Cluster analysis based on these two indices classified hybrids into two groups under mild stress and in three groups under severe stress conditions. Biplot graphs for two main components based on principle components analysis (PCM) displayed that SC500 to be a tolerant maize hybrid in both mild and severe drought stress conditions with high yield performance. Also, hybrids SC700 and SC704 were low yielders under both control and stress conditions and thus were identified to be as sensitive hybrids.   Manuscript profile

In order to study genetic variation and heritability in fifteen cultivars of red clover in climate conditions of Broujerd an experiment in based on randomized complete block design (RCBD) with three replications under irrigated conditions in Agriculture Researches Center and National Resources of Broujerd in 2013-2014 cropping year was carried out. The measured traits were including of dry and wet forage yield in three cuts, plant height, digestibility percentage, crude protein percentage (%CP),Water soluble carbohydrates (%WSC), insoluble fiber in acid percentage, crude fiber percentage (%CF) and ash percentage (%AH) in two cuts and ratio leaf to stem and regrowth rate in one cut. The qualitative traits were measured by near infrared reflectance (NIR) technology. The results of analysis of variance were indicated that differences between cuts for all traits and genotype effect and interaction genotype × cut for all traits except plant height and ash percentage were significant. Compare means, Duncan method were showed Chamran, Renova, Shahrecord and Reszti cultivars with range between 52 to 56 t.ha-1 wet forage and range of 17.3 to 18.3 t.ha-1 dry forage in general three cuts had the highest forage yield. In among them Renova and Shahrechord cultivars had the highest plant height and ratio leaf to stem, but Charmahal had high mean for qualitative traits including digestibility and total ash and low mean for ADF and %CP. low In other words, it had higher forage yield and quality. In comparison between means of cuts, the highest and lowest forage yield related to 1 and 3 cuts, respectively. Simple coefficients of correlation among forage yield with plant height and digestibility was positive and with ratio leaf to stem and soluble carbohydrates in water was negative and significant. Coefficients of correlation between digestibility and protein percentage were positive and significant and these traits had negative and significant correlation with soluble carbohydrates in water, percentage crude fiber and ADF. Results of principal components analysis (PCA) for 15 genotypes in 11 traits showed three first principal components explained 72% from total variation. In the first component, wet forage yield, digestibility percentage, crude protein percentage and soluble carbohydrate in water explained the highest variation. In the second component, plant height, insoluble fiber in acid, crude fiber percentage, total ash percentage had the highest vector coefficients. In the third component, dry forage yield with ratio leaf to stem had negative correlation. In cluster analysis base on the ward's method 15 genotypes of red clover for 11 traits placed in three clusters. Shahrod and Renova Cultivars placed in cluster number 3, and had high forage yield and medium digestibility percentage, crude protein percentage and soluble carbohydrates in water. In contrast, cultivars placed in cluster number 2, had medium yield but better quality. Cultivars placed in cluster number 1 had lower values for quantitative and qualitative traits.

In order to investigation of different levels of salinity stress effects on germination, vegetative and some germination indices an experiment was performed in factorial form using a completely randomized design with 3 replications at Seed and Plant Improvement Institute Karaj. First factor encompass 20 genotypes (including narin, Ofough and Arg varieties as checks) and second factor four levels of salinity treatment (0 ,8, 12 and 16 ds/m), were used. Traits germination percent, germination rate, radicle length, plumule length, seedling length, plumule /radicle length ratio,dry weight of radicle , dry weight of seedling, plumule /radicle dry weight ratio, germination uniformity ,seed vigor index and salinity tolerance index (TI) were studied. Results analysis of variance showed that between genotypes, salinity stress and their interaction for all traits had significant difference. The most and the least of TI was belonged to genotype no.10 (Ti=83.13%) and genotype no 8 (Ti=54.82%) respectively. Salinity tolerance index (TI) had positive and significant correlation with germination percent, germination rate, plumule length, dry weight of seedling, plumule /radicle dry weight ratio and seed vigor index. Based on cluster analysis genotypes were divided into 3 different groups. Finally based on salinity tolerance index and all of germination traits, and results of cluster analysis, genotypes no 5,20, 10 and 14 were determined as the most tolerant genotypes and better than checks cultivars, that can be recommended to using of this genotypes for future breeding programs tolerance to salinity stress, and genotypes No. 8, 11 and 17 as the most susceptible genotypes.

In order to assessment of sugar beet varieties by using multivariate statistical methods in agro ecological conditions mentioned in normal and drought conditions a field study was conducted in Agriculture research center in Miandoab during year of 2014.Result of combine analysis showed environment had significant effect Root yield, sugar content, the amount of sodium root, white sugar content, sugar yield, alkaline extraction of sugar and molasses. Difference between genotypes for all traits, except for the amount of potassium was significant. The interaction between environment and genotype had significant on all pages except white sugar yield. In represent study in normal and drought conditions white sugar yield had positive and significant correlation root yield, root potassium concentration, sugar yield and extraction of sugar. Based on cluster analysis genotypes were classified in 4 clusters under normal conditions that genotypes in cluster 2 had highest amount of root yield, sugar yield, the percentage of sugar white and white sugar yield than the average of the whole clusters and lower amount of sodium, potassium, amino nitrogen and molasses than average of the whole clusters. in drought stress genotypes were classified in 4 clusters that group of 3  had highest value of root yield, sugar percentage, amino nitrogen, the percentage of white sugar, sugar yield, extraction of sugar and white sugar yield than the average and had lower amount of sodium, sugar molasses and alkaline than average. The results of factor analysis showed in normal and drought conditions 2-factor were identified that explained 97.77 and 94.85 per cent of the total variance in the two conditions respectively.
