Genetic divergence study was conducted by using 30 diverse genotypes of cabbage for 11 characters. Based on Mahalanobis D2 analyses using to tocher's method the genotypes were grouped into 3 clusters. For morphology and yield characters, intra-cluster average ranged from 2.241 to 5.304 the intra-cluster value was maximum in cluster II (3.057) and minimum in cluster III (2.241). The maximum inter-cluster distance was obtained between cluster I and II (5.304) while the minimum distance was found between clusters I and III (2.241).Cluster II showed superiority for certain morphological and horticultural traits. The cluster-wise mean performance suggested that genotypes Pusa Ageti, 1923, KK-3, KK-2 and RRM of cluster-II, in cabbage respectively, could be utilized effectively in hybridization programme for getting desirable segregants. In the present study five characters contributed 78.09% of divergence, namely, five characters contributed % of divergen viz, days to maturity (38.19%), number of non-wrapper leaves (12.05%), core length (11.31%), stalk length (9.01%) and leaf width (7.53%), of the total divergence.
