Heterosis in mungbean [Vigna radiata (L.) Wilczek].

Study of heterosis in 21 different hybrids of mungbean resulting from 7 x 7 diallel, excluding reciprocals indicated pronounced hybrid vigour for yield and most of the yield components. Heterosis to the extent of 63.45 and 61.69% over the mldparent and better parent respectively was recorded for grain yield per plant. Heterosis for yield was generally accompanied by heterosis for yield components. Seven hybrids were identified as promising for many desirable traits and they may be of much use in exploiting hybrid vigour in mungbean.
