The experiment was performed at the Experimental Farm of Agronomy Department, Faculty of Agricultural, Al-Azhar University (Assiut Branch), Assiut, Egypt during the three successive seasons of 2016/2017,2017/2018 and 2018/2019. Seven parents of bread wheat (Triticum aestivum, L.) of a wide diversity for some agronomic traits were selected for the study, namely Sids1 Sids12, Sids13, Shndaweel1, Giza 171, Gemmeiza 11 and Sakha 93. The parents were crossed in 2016/2017 and 2017/2018 growing seasons in a half diallel fashion. The parent and crosses were evaluated in 2018/2019. Results indicated that mean squares of genotypes, general and specific combining abilities were significant (p≤0.01) for all traits, except number of kernels /spike. The ratio of GCA/SCA genetic components were less than unity indicating the greater amount of non- additive gene action determining the performance of all traits. The crosses (Sids 12 × Sakha 93), (Giza 171 × Sakha 93), (Gemmeiza 11 × Sakha 93), (Shandaweel 1 × Sakha 93) and (Sids 12 × Giza 171) recorded greatest mean values for grain yield /plant. Sids1 and Giza171 were considered as the best general combiners for grain yield /plant. The best crosses showed significant (p≤0.01) SCA and heterotic effects for grain yield /plant were Sids 1 × Sids 13, Sids 12 × Shandaweel 1, Shandaweel 1 × Sakha 93, Giza 171 × Gemmeiza 11 and Giza 171 × Sakha 93 so, they could consider promising hybrids in breeding programs for crop improvement.
