Abstract:
Genetic diversity among 42 genotypes of groundnut was estimated for ten characters using Mahalanobis D² statistics. Tocher's approach was used to divide genotypes into groups. The genetic diversity analysis revealed the formation of eight clusters suggested the presence of considerable genetic diversity among the 42 genotypes. Inter-cluster distances were higher than intra-cluster distances for mostly cluster, indicated the existence of substantial diversity among the genotypes. Among 8 clusters, cluster II was the largest having fifteen genotypes followed by cluster III (11) and cluster I (9), while cluster V, VI and VIII were solitary. Cluster IV and V has the maximum divergence because they contain desirable mean values for different characters. While, harvest index (52.03%) contributed the highest for divergence followed by pod yield per plant (20.56%) and number of mature pod per plant (12.89%). So, selection for divergent parents based on these characters would be useful for developing potential hybrids.
