Abstract
Water deficit conditions is considering one of the most important environmental constraints that reduce crop productivity to a large extent and hence the wheat crop. Therefore, the genetic improvement for increasing drought tolerance in wheat is one of the most important strategic challenges in this regard. Because of wheat is considering the artery of food not only for the human race, but also for all living things and this food has been known to man since the dawn of time.Five wheat cultivars and their F1 crosses with different reaction for water stress tolerance were estimated under normal and drought conditions to study the genetic behavior responsible for drought tolerance passed on some genetic parameters obtained from half diallel analysis through studying some yield attributes. Mean performances, heterosis over better-parent, general and specific combining ability effects and drought tolerance indices were the most genetic parameters calculated. The final results revealed that the entries; Sakha 94 and PGH-OR 12, Sakha 94 X Shandweel1, PGH-OR12 X Chah "s"/6/Maya/vul//Cmh 74 a. 630 /4*sxs.16342 and PGH-OR 12 X PFSW 343*2/Tukuru were the best genotypes for water stress tolerance and detected highly values of yield traits and revealed highly significant positively for the previous genetic measurements, respectively. The recent wheat accessions were exhibited highly water stress tolerance under the stress treatment compared to the control experiment through evaluationg all studied traits. The final results also indicated the great genetic value, which was transgressive segrgation of the seven wheat genotypes which gave excellent positive results for drought stress.
