Studies on heterosis for yield attributes in mungbean (Vigna radiata L. Wilczek)

The magnitude of heterosis over better parent and standard variety for yield attributes in mungbean were studies by twenty eight crosses resulting for 8 x 8 diallel excluding reciprocal. 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 either one or more 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 desirable segregants.
