Abstract

The genetic diversity among 105 groundnut germplasm for 11 characters was measured by employing D2 statistic and these were grouped into 15 clusters. The average D2 values of inter cluster distances, showed maximum distance between Cluster V and XV (12283.79) followed by inter cluster distance (11278.47) between III and XV. The clusters were ranked based on the overall score across 11 traits. Accordingly, cluster X was superior which indicates the presence of most promising genotypes in them. Hundred pod weight and harvest index had maximum contribution of 43.64% and 21.76% respectively to the divergence of genotypes.
