Direct and indirect effects of the quantitative traits including four synchrony traits on the grain yield of wheat have been studied under two environments with close plantings. Tillers per plant had the highest direct effect on yield. This trait not only contributed indirectly but some other characters also influenced yield positively via this attribute. Weight per ear and synchrony of height were another important components which contributed directly and indirectly in the positive direction to the grain yield. Height and synchrony of grains per ear had negative direct effect on yield. In the light of these finding component breeding with greater emphasis on tillers per plant, grain weight/ear and sanchrony of height has been suggested.
