Abstract
The experimental field work was conducted at Gemmeiza and Sakha Agricultural Research Stations, (ARC), Egypt, in 2017/18, 2018/19 and 2019/20 seasons to study the genetic behavior of grain yield and yellow rust resistance in three bread wheat crosses. The Genetic materials included (P1, P2, F1, F2, BC1 and BC2) of Gemmeiza 11× Giza168 (cross 1), Sids12 × Shandaweel1 (cross 2) and Gemmeiza 12 × Shandaweel 1 (cross 3). Significant differences were observed among most genotypes for measured traits. Additive gene effects were negative and highly significant in the first and the third crosses for No. days to maturity and grain yield plant-1 and in the second cross for No. spikes plant-1. However, it was positive and highly significant in the second cross for 100-kernel weight, yellow rust resistance and grain yield plant-1. Narrow sense heritability was ranged from moderate to high values for plant height, yellow rust resistance and No. kernels spike-1 in all studied crosses. These results could be employed to improve both yield and rust resistance in Egyptian wheat breeding program.
