The present investigation on genetic analysis involving 12 parents and 20 crosses in mung bean indicated that VC-1, TARM-18, TARM-1 and Vaibhav were the good general combiners based on the overall score across the traits in desirable direction. The cross combination ChinamungxVC-1 exhibited significant sca effects for traits viz., seed yield per plant, seed yield per plot, number of pod bearing cluster per plant, number of pods per plant, hundred weight and harvest index. Gene action study revealed that days to 50% flowering, days to maturity, number of pods per plant, hundred seed weight (g), total dry matter at harvest (g), harvest index (%), seed yield per plant (g) and seed yield per plot (g) in the present study were governed predominantly by additive genetic variation. Since all these characters were also under significant influence of epistatic variation, it appears that additive x additive epistatic variation may be playing a decisive role in the inheritance of these characters.
