Studies were carried out on the inheritance pattern of the important yield parameters viz., tillers per plant, spike length, grains per spike, 1000 grains weight, harvest index and yield per plant of 8 bread wheat varieties. The component analysis indicated that the additive component was significant for all the traits except tillers per plant and yield per plant. The dominance component was significant for spike length, tillers per plant and yield per plant. Regression analysis revealed additive type of gene action for grains per spike, 1000 grains weight and harvest index and over dominant type of gene action for rest of the traits. Correlation analysis of dominant genes with the phenotype of the parents revealed recessive gene control for tillers per plant and spike length, while dominant gene control was indicated for rest of the traits studied.
