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

Heterosis for yield and its components over better parent and mid parent was studied among eight genotypes of Mungbean (Vignaradiata L.). Total 28 F1s were generated from above genotypes in diallel fashion. The highest heterosis to the extent of 34.25% over better parent and 37.06%over mid parent forseed yield per plantwas observed in the cross Meha x GJM-1004. Meha x GJM-1004, GJM1004 xGJM-1006, Meha xGJM-1008 and GJM-1007 xGM4 were identified as promising hybrids, having increased potential to exploit the hybrid vigour or to isolate the desirable segregants. In general, heterosis for seed yield in mungbean might be the result of combined heterotic effects of different yield contributing characters.
