Genetic analysis for six quantitative characters in five crosses of mungbean {Vigna radiata (L.) Wilczek} was carried out through generation mean analysis using five parameters model. The studies indicated predominance of additive effects for days to flowering, pods/cluster, pods/plant and 100seed weight in most of the crosses. The dominance effect was also noticed in most of the crosses for clusters/plant, pods/plant and seed yield/plant. Among the epistatic effects, significant additive x additive (i) interaction were observed in 3 crosses for clusters/plant and in two crosses for seed yield/plant, whereas significant dominance x dominance (l) interaction was observed for days to flowering, pods/cluster and pods/plant in one cross. As all the three types of gene effects are involved, the recurrent selection and diallel selective mating will be effected for the genetic improvement in mungbean.
