Twenty one crosses resulting from 7 x 7 diallel excluding reciprocals were studied to know the magnitude of heterosis over mid parent and better parent for seed yield and its components in mungbean. The highest heterosis to the extent of 26.1% over mid parent and 22.8% over better parent for seed yield per plant was observed in the cross BM 4 x TARM 18, which exhibited high heterosis (%) for either one or more yield components. The promising hybrids viz.,BM 4 x TARM 18, Vaibhav x TARM 18, AKM 8802 x BM 4 and Kopargaon x TARM 18 were identified, which have immense potential to exploit the hybrid vigour or to isolate desirable segregants.
