ABSTRACT
The present study was conducted to assess the general combining ability effects of parents and specific combining ability effects of hybrids for yield and yield related traits and explore their use in hybrid development. 45 F1s generated by 10 × 10 half diallel were evaluated. The ratio of sca / gca variance revealed that there was preponderance of additive gene action in the expression of yield and yield contributing characters viz,. ear length, number of grain rows per ear, 100-grain weight, grain yield per plant, harvest index under study. Parent P1 (Number of grain rows per ear), P6 and P7 were good general combiners for another yield and yield attributing characters. Hybrid P1 x P5 showed highest positive significant sca effects (48.60) along good per se performance (151.67 g/plant) and positive significant economic heterosis (26.39 %) for grain yield per plant. This hybrid also exhibited positive significant sca effects for 100-grain weight and harvest index. Another hybrid P6 x P7 showed good sca effect (35.07) along with highest economic heterosis (41.67 %) and maximum per se performance (170.00 g/ plant) for grain yield per plant.
Key words: Maize, half Diallel, Yield and yield contributing characters, general combining ability and specific combining ability
