This study was conducted with purpose of investigate the effect of drought stress on different growth stages of 20 maize hybrids in farm of Seed and Plant Improvement Institute in 2016. Drought stress levels consisted of four experiments (normal irrigation, stress in vegetative stage, reproductive stress and irrigation interruption as compared to control) in a randomized complete block design. The results of analysis of variance showed that genotypes in terms of traits in each non-stress condition, stress in vegetative stage, stress at reproductive stage and alternate condition have a significant difference at levels of 1 and 5%. According to the results obtained from genetic parameters, in the normal experiment, the number of days to tassel flower initiation, in the vegetative stress experiment tassel branching out number, in the reproductive stress experiment the number of aborted seeds and in the alternate condition days to the drying of the tassel had higher heritability. The tassel branching out number showed the highest phenotypic variation coefficient (77.15) and number of seeds per ear row, the highest genotype variation coefficient (75.6) in normal experiment. Respectively, the number of aborted grains (47.7%) and peduncle outside flag leaf (29.10%) in the vegetative stress test, had the highest phenotypic and genotypic diversity coefficients. The highest phenotypic and genotypic diversity coefficients in reproductive stress test were observed in number of seeds inoculated trait with 45.8% and 37.2%, respectively. Manuscript profile

Genotype safflower is scattered throughout the world from India and China to Africa and Europe. The aim of this study was to determine the relationship between plant yield, yield components and morphological traits, as well as accurate recognition of traits affecting the yield on 32 safflower genotypes in a randomized complete block design with three replications at the research farm of Islamic Azad University, Karaj Branch. Among the studied genotypes, there was a significant difference in all studied traits such as plant yield, 1000-seed weight, number of branches, number of bolls per plant, boll weight, flowering time, flowering time, plant height and flowering time until there was an examination that indicated a high diversity in the germplasm studied. Among the yield components, the most heritability was attributed to 1000 seed weight and number of branches, and the lowest heritability was attributed to plant yield, which indicates that indirect modification of yield would be more beneficial. Plant height and number of branches can be used as an index of selection in breeding programs. Cluster analysis based on morphological traits categorized genotypes into five clusters. Based on the results of this study, it can be stated that by improving the traits of boll weights and number of bolls per plant, it is possible to achieve the desired grain yield in safflower genotypes.
