AbstractGenetic effects on grain yield (GY) were determined in four wheat crosses using mixed inheritance model. GY in cross 1 was controlled by Model E while it was under control of Model E-1 in other crosses. Additive effects of two major genes were observed in cross 1 while additive effects due to several polygene and negative additive effects related to the major genes were observed in controlling GY in the rest of the crosses. Transgressive segregates in the segregating populations of all the crosses indicated the presence of favorable and adverse genes in the parents for GY. Major genes heritability was higher than that of the polygene in the segregating populations of all the crosses with highest environmental influence. Additively controlled nature of the trait predicts that selection of desirable recombinants for higher GY may be delayed up to advance generations until favorable genes are accumulated in homozygous condition.
