Abstract
Graphic and component analysis of five different genotypes of bread wheat (Triticum aestivum L) namely LU-26, Pak.81, Pb. 85, S-131 and S-1080, indicated the presence of additive genetic variance with partial dominance for peduncle length, spike length. spike lets per spike and number of grains per spike while complete dominance was reported for grain yield per plant. Wheat genotypes Pak. 81 and S131 showed relatively higher combining ability. From the preponderance of additive genetic control and absence of epistasis, it may be suggested that careful selection of desirable traits in early segregating generations would provide fruitful results.
