Abstract:

Identifying the genotypes with high further transfer ability especially in grain filling period, can be a proper factor for selection in drought stress condition. In this study, in order to evaluate the amount of photosynthetic substances gathering in the grain, 19 varieties of bread wheat in the form of random complete blocks design were studied with three replications in drought stress and normal conditions. The mean grain yield genotypes in normal and drought stress conditions were respectively 5151 and 2628 kg/h. The difference among the genotypes was significant in both of conditions from different evaluating traits points of views. In normal condition, the most and the least grain yield were respectively 6580 and 4275 kg h and in drought stress condition they were 4217 and 1650 kg/h. Correlation between the grain weight per spike was positive and significant with thousand-kernel weight in normal condition (r = 0.562). On the other hand an increase of substances weight in grain filling time causes a decrease in the amount of substances transfer to the productive part of the plant, and consequently it results in yield decrease in drought stress condition.
