Heterosis for yield and its contributing characters in mungbean (Vigna radiata (L.) wilczek)

Twenty eight crosses resulting from 8 x 8 diallel excluding reciprocal were studied to know the magnitude of heterosis over better parent and standard variety for yield and its components in mungbean. The highest heterosis to the extent of 80.76% over standard variety and 72.39% over better parent for seed yield per plant was observed in the cross Narendra Mung-1 x PS-16 which exhibited high heterosis percentage for yield and yield components. The promising hybrids viz. Pusa Baisakhi x Pusa bold (vishal), Pusa Baisakhi x Pant M-3, Narendra Mung-1 x PS-16, Pusa Baisakhi x Pusa-105, Pusa Baisakhi x ML-613 were identified which have increased potential to exploit the hybrid vigour or to isolate the desirable segregants.
