Abstract: Seven genotypes of mungbean were studies in diallel with fixed effect model (method II). All the parents and crosses showed significant positive as well as negative general combining ability (GCA) and specific combining ability (SCA) effects for the traits. HUM-16 and IPM-410-3 with significant negative GCA estimates for days to maturity were good general combiner and possessed favourable genetic architecture for early maturity. The general combining ability results indicates that the parent LBG-460 is good general combiner for all the traits except seed yield per plant and harvest index. The cross combination, BM-4 x Pusa Vishal with high SCA effects for number of pods per plant, plant height and days to 50 % flowering, while the cross HUM-16 x RMG-1028 showed significant SCA effects for all the traits except for number of branches per plant. The study revealed non additive gene action involved in controlling all the characters namely, days to 50 % flowering, days to maturity, plant height, number of branches per plant, pods per plant, pod length, seeds per pod, protein content, yield per plant etc. These crosses could help in further development of transgressive segregants with superior combinations of alleles for yield and yield contributing traits.
