Abstract:

Genetic divergence of 40 soybean genotypes was studied for eleven quantitative traits using Mahalanobis’s D2 statistics during Kharif-2019 in Randomized Block Design with three replications. Analysis of Variance showed significant differences for all characters under study at 1% and 5% Level of Significance. High estimates of GCV and PCV were observed for number of pods per plant followed by seed yield per plant. High heritability coupled with high genetic advance was recorded for plant height followed by test weight. Based on the relative magnitude of D2 values, the genotypes were grouped into nine clusters. Cluster III constituted maximum number of genotypes with 19 genotypes followed by cluster I. Maximum intra-cluster distance was found in cluster III followed by cluster II. Maximum inter-cluster distance (D2) was observed between cluster III and V. Test weight contributed maximum towards genetic divergence. Based on inter cluster distances and Per se performance, the genotypes TNAU 20051, MAUS 128 and KB 17 with test weight traits should be given top priority during selection of the genetically divergent parents in future breeding program.
