COMBINING ABILITY ANALYSIS IN VARIETAL CROSSES OF MAIZE
Main Article Content
Abstract
Eight varieties of maize were evaluated following diallel mating design for determining their utility as parents in the development of hybrids and/or high yielding composites. For days to SOO/. tasselling and silking. and·l000-grain weight, variety (Vi) effects; for plant and ear heights, ear length and diameter, both Vi and specific heterosis (Sij) effects; and for grain yield, sll effects were the most important contributors to the total entries sum of squares. Average heterosis di) and variety heterosis (hi) effects were not so important for any trail. Cross between cvs. Navin and Population 26 showed significant and positive Sij effects for grain yield, plant height, ear height and ear length. These two varieties represented a good choice to initiate interpopulation improvement.
