| Abstract | ||
| Inheritance of yield, combining ability and inbreeding depression were investigated in durum wheat of F2 half diallel crossing among the 7 varieties Vis: Leeds, Waha, Azeghar1, Um-Rabie3, Brashua, Cyprus1 and Korfila. Genotypes, general and specific combining ability mean square were highly significant. The durum wheat yield was under the dominance gene effect. The parents Leeds and Um-Rabie3 were considered suitable according to their yield capacities and general combining ability effects. The two hybrids (Leeds x Brashua) and (Waha x Brashua) had significantly higher yield (2.943 and 2.955 ton per hectare respectively) as compared with others, and also possessed significant positive specific combining ability effects, highly significant positive inbreeding depression values and deviation from local variety Um-Rabei5, therefore they were considered to be promising hybrids. | ||
