Combining Ability Analysis in Mungbean (Vigna Radiata (L.) Wilczek)

Combining ability analysis of 28 F₂’s of a diallel cross (excluding reciprocals) and their parents showed that both additive and non-additive components of variation were important in the inheritance of grain yield/plant and 100-seed weight. For plant height, pods/plant and seeds/plant, only the additive component was important. The parent EC 30072 was adjudged as a good general combiner for grain yield/plant, whereas VBN 1 and PMB 27 were adjudged as good general combiners for 100-seed weight. Six cross combinations viz., VRMGG Local/VBN 1, VRMGG 1/EC 30072, VRMGG 1/PMB 27, EC 30072/LGG 410, M 123/LGG 450 and VBN 1/PMB 27 recorded high specific combining ability and could be exploited for further breeding programmes.
