Abstract: Diallel crosses involving genotypes K-65, LU26S, 6500, 5039 and 1671-1 should additive. Genetic variance with partial dominance was observed for all the characters studied except spike length where over dominance was observed. Epistatic effect was absent for all the characters. The genotype 1697-1 seems to be the best source of height reduction as it contained most recessive genes and its grain yield per plant was also high after K-65. These two lines could be used in the breeding programme to develop high yielding wheat varieties.
