Sixty genotypes of mungbean (Vigna radiata L. Wilczek) were evaluated for 13 characters to assess genetic variability, heritability, correlation, genetic advance and genetic diversity. Total dry matter, plant height, number of pods per plant and yield per plant exhibited high variability and heritability coupled with genetic advance indicating the influence of additive gene action. Correlation studies indicated that the total dry matter, number of pods per plant, number of clusters per plant, number of branches per plant and days to 50% flowering were positive and significantly associated with seed yield. Total dry matter and number of pods per plant had direct positive effect on seed yield while plant height had negative effect. The results of multivariate analysis indicated the presence of considerable genetic divergence among the genotypes studied. The genotypes were grouped into eight clusters. Days to maturity, 100-seed weight, number of pods per plant and total dry matter contributed maximum towards diversity. Crosses can be effective between the genotypes of cluster V and VII followed by cluster I and VII where the maximum inter-cluster distance was exhibited for getting desirable segregants.
