Morphological Diversity for Yield and Its Component Traits in Mungbean [Vigna radiata (L.) Wilczek]

The current experiment was held in Summer season, 2018 at rice upland 1, near rice bore well of Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India. The experiment was done by 36 Mungbean genotypes at rice upland 1, near rice bore well of Bihar Agricultural University, Sabour, Bhagalpur in 2018. The analysis of variance (ANOVA) disclosed highly significant differences for all the traits studied in the experiment among all the genotypes. The genetic diversity was estimated by D2 analysis. The 36 genotypes were grouped into 11 distinct clusters with cluster 4 to cluster 11 consisting of one genotype each. The maximum inter-cluster distance was found between cluster 11 and cluster 3 where maximum intracluster distance was found within cluster 2. The characters like Harvest index, the number of clusters per plant, seed yield per plant and days to maturity contribute maximum towards genetic divergence. The hybridization between the clusters 11 & 3 could give maximum heterosis and better desirable segregants.
