Nature of gene action was investigated for various agronomic characters such as plant height, ear height, number of days taken to tasseling and number of days tasseling in a set of complete diallel crosses, involving six elite maize inbred lines (B 70, EX 228, FR 15, N 28, PA 91, SYP 5). The Vr-Wr graphs indicated over-dominance type of gene action for ear height and additive type of gene action for all other traits. It was revealed that inbred line FR 15 and SYP 5 possessed most dominant genes for plant height and ear height respectively. Similarly inbred line B70 contained most dominant genes for number of days taken to tasseling and number of days taken to silking. The three characters like plant height, number of days taken to tasseling and number of days taken to silking were under the additive genetic control and mass selection can be practiced for these characters, whereas ear height was non-additively controlled and selection for these populations must be practiced with great care to develop pure breeding line.
