Genetic divergence analysis in 60 genotypes of Indian mustard [Brassica juncea (L.) Czern & Coss.] by applying Mahalanobis’s D2 statistics indicated the presence of wider genetic diversity among the material for 14 characters. The genotypes were grouped into eight clusters by Tocher’s method. Cluster IV was the largest group with 18 genotypes, whereas cluster I was the second largest group consisting 16 genotypes followed in order by cluster VI (8 genotypes), cluster II (7 genotypes) and cluster III (6 genotypes). Two clusters, V and VIII comprised of two genotypes each cluster, while cluster VII comprised only one genotype (RH 406). The highest intra-cluster distance was observed for cluster VI (47.94). The highest inter-cluster distance was observed between cluster VIII and V (52.40). The maximum contribution to divergence was from seed yield per plant (11.76 %) in present investigation.
