Estimates of gene effects based on analysis of generation means were obtained for four yield traits, namely, grains/spike, grain weighto F3 spikes, yield/plant and 100-grain weight in several crosses of breadwheat (Triticum aestivum L. em Thell). The contribution of additive gene effects (d) were important in the inheritance of number of grains/spike and 100-grain weight, whereas the dominance gene effects (h) contributed significantly for grain weight of 3 spikes and yield/plant. Among the epistatic effects, additive x additive interactions was of considerable importance for all the characters.
