Genetic Divergence and Correlation Analysis in Mungbean (Vigna Radiata L. Wilczek)

Sixty-four mungbean lines collected from different sources were evaluated for yield and yield contributing traits. Wide range of means was observed for all the traits. High heritability coupled with high genetic gain was observed for 100-seed weight, pods per plant, clusters per plant and plant height. All the genotypes irrespective of their place of collection were grouped into eight clusters each having 37, 09, 01, 07, 01 and 01 genotypes, respectively. Cluster II showed maximum genetic distance and cluster I showed maximum closeness to all other clusters. Grain yield showed significant positive correlation with pods per plant, clusters, per plant, pod length, seeds per pod and 100-seed weight, while significant negative association with days to 50% flowering. Results suggested that genotypes from the cluster I, II, IV, VI and VIII may yield better recombinations. The 100-seed weight contributed most towards genetic divergence. All the genotypes having bolder seed size grouped in cluster II.
