Abstract
A dialiel cross involving five bread wheat genotypes were evaluated to dete‘mine the genetic behavior of yield and its components in wheat under drought concitions. The resultant hybrids along with their parents were evaluated in two experiments The first experiment was irrigated once (stress). while the second one was irrigated four times (normal) The parents. P: (Sahel 1) . P; (Gemmeza 9) and P: (Sakha r31) expressed the highest GCA for number of kernels” spike, as R (Sahel t) and P; (Gemmeiza 9) for number of spikes .' plant. while P3 (Giza 164) was the highest for 100 kernels weight and grain yield i’ plant. Atso. P«(Sahel 1) had good potential for grain yieldiplant. The highest SCA values were detected for the cross Sahel 1 ‘ Sakha 94 for number of kernels” spike and 100 kernel weight, Giza 15-1 i’ Sakha 61 for number of spikes .i‘ plant and number of kernels spike. and Sahel 1 .‘ Gemmeiza 9 for number of spikes’plant and grain yield plant,
