Abstract:
The investigation was conducted with thirty-six mung bean genotypes under two seasons i.e., Kharif 2019 and zaid 2020 to identify the diverse genotypes for utilization in hybridization through genetic diversity analysis. Thirty-six genotypes were grouped into seven clusters. Cluster I and cluster II were polygenotypic and were the largest clusters each comprising of 18 and 25 genotypes in Kharif and summer respectively. During the Kharif season, Cluster II showed maximum intracluster D² value. Cluster I showed maximum intracluster D² value followed by cluster II for the summer season. The number of seeds per pod (43.33%) and biological yield per plant (g) (44.29%) contributed towards maximum genetic divergence. Entries from cluster II and cluster I were found to be superior and highly diverse, thus suitable as parents for hybridization. The potential genotypes based on the D² statistics under both seasons were found as SML 1831, PDM-139, TM-37 and Ganga-8.
