Six populations of two wheat hybrids, namely Sids 14 × Giza 171 and Sids 14 × Gemmeiza 11 were established during three successive seasons of 2017/2018, 2018/2019 and 2019/2020. The results showed that there are significant differences between the mean of six populations in the cross- crossing of wheat crosses for most the studied traits, it is possible to obtain sufficient amounts of genetic variation for these traits in the studied material. Theadditive gene effects were significant for all traits studied except for DH in cross 1 and NSP in cross 2. The highest significant effects of the dominant genes were found to be highly significant for most traits under study, except for the number of grains/spike in the hybrid 2. The additive × additive type of gene effects was positive and highly significant for plant height and weight of 100 grains in the two crosses, and 50% flowering to heading and grains yield/plant in cross 1. High expected genetic advance was recorded in the second generation (F2) for grain yield per plant in the two hybrids, The results showed that there is an improvement in the genotypes possible through early selection of the higher crop.
