| Abstract |
A partial diallel crosses mating design was made among six common wheat cultivars and lines during 2003/2004 and 2004/2005 at El-Giza Agric. Res. Station, ARC. Significant mean squares were obtained for genotypes in all the studied characters, parents except No. of spikes/plant, 100-kernel weight and grain yield/plant, crosses except No. of spikes/plant, No. of kernels/spike and grain yield/plant and parents vs. crosses except No. of spikes/plant and No. of kernels/spike. The mean squares associated with GCA and SCA were significant for most studied traits which indicated the presence of both additive and dominance types of gene effects. The ratio of GCA/SCA were more than unity in all traits except grain yield/plant indicated that additive and additive x additive gene effect was more important than dominance gene effect in the expression of these traits. The crosses P2 x P4, P1 x P4 gave significant values for heterosis relative to better parents for grain yield/plant recording 84.51% and 64.41%, respectively
