The mode of inheritance and gene effect for plant height of 7x7 half diallel crosses of wheat varieties and lines was evaluated in F1 and F2 generation. The mode of inheritance, calculated for each combination separately, was different and depended on the cross combination. The absence of interallelic interaction between the genes determining the expression of plant height was concluded from the regression analysis. The regression line intercepts the Wr axis below the origin in F1 indicating overdominance over an average of all arrays. In F2 the regression line cuts the Wr axis above the origin indicating partial dominance
