Abstract
The aim of this study was to assess the variations among set a half diallel cross using eight varieties for drought characters, estimating combining ability and genetic components. For this objective, the investigation was carried out at the Experimental Farm of Etay El-baroud Agricultural Research Station during the two seasons of 2015/2016and 2016/2017, Eight diverse wheat varieties (Triticum aestivum, L.) and 28 F1's were planted in two experiments. The first experiment was normally irrigated 4 irrigations (Non stress) and the second one was irrigated one time after planting irrigation (Stress). General (GCA) and specific (SCA) combining ability mean squares were highly significant for all studied traits in both environments as well as the combined analysis. Such results indicated that both types of combining ability are important in the inheritance of these traits.It could be concluded that the parent P7 (Giza 171) seemed to be the best general combiner for grain yield/ plant and most of yield components.
N. kernel / spike in both exuberant and the combined only s , 1000 kernel weigh and harvest index in the drought treatment and the combined ability and grain yield in the normal irrigation. 
The best ŝij effects were detected for the crosses P6 (Misr1 )x P7 (Giza171), P7 x P8 (Giza168) and P1 (Gemmeiza) x P6 Misr 1 at both conditions and their combined for grain yield and some traits stadied.
