Abstract

Combining ability analysis of 28 F1’s of a diallel cross (excluding reciprocals) and their parents showed both additive and non-additive components of variation for the inheritance of grain yield/plant and 100 seed weight. For plant height, clusters/plant, pods/ plant and seeds/pod, only the additive component was observed. The parent KU 300 was adjudged as a good general combiner for grain yield/plant, whereas, TU 94-2 and P 165 were adjudged as good general combiners for 100 seed weight. Six cross combinations viz., 2 KU 53/TU 94-2, 99 V 48/KU 300, 99 V 48/P 165, KU 300/LBG 645, PV 94-2/LBG 623 and TU 94-2/P 165 recorded high specific combining ability and they could be exploited for further breeding programmes.
