Abstract:

An investigation was carried out across four environments to assess magnitude of heterosis and combining ability of 30 hybrids developed by crossing three females and ten male lines in line x tester fashion. Non-additive gene action played a major role in the inheritance of most of the traits (viz., days to 50 per cent flowering, days to maturity, plant height, number of primaries panicle-1, panicle weight, fodder yield plant-1, grain yield plant-1, leaf area index and harvest index) under study except panicle length, number of grains panicle-1 and 100 seed weight for which additive gene action was found to be important. Based on consistent performance over four environments, AKMS-30A, AKR-504, Rb-342-2 and AKR-354 were found to be best general combiners for grain yield and yield related traits. Among the hybrids, AKMS-30A X Rb-324-3, AKMS-70A X AKR-354, AKMS-70A X Rb- 342-2 and AKMS-30A X Rb-301-4-1 were found to be good specific combiners with highest standard heterosis and per se performance for grain yield plant-1 over the environments.
