Abstract: The experimental materials included 3 crosses from 6 parents of wheat. Generation mean analysis method was used to study gene effect of plant height, leaf number per plant and 1000 grain weight at different growing stages. Algebraic symbol and significance of the gene effect, and genetic model for each character showed distinct changes with its growing stage and its parents of the cross,which were considered as the result of actions of different gene loci at each stage and the genetic structure of the population derived from different parents. The addtive dominance model fited to the inheritance oF ₁000 gain weight, but epistatic effects were present in the inheritance of plant height and leaf number per plant.

Key words: Wheat, Growing stage, Gene effect
