Genetic Divergence, assessed in sixty genotype of Indian mustard using D2 statistic for fifteen developmental characters, showed grouping of the genotype into four clusters. Cluster I was the largest, consisting of fifty genotypes. Cluster II showed maximum genetic distance from cluster IV, suggesting wide diversity between them. Siliqua length, seed yield/plant, 1000-seed weight and number of days to maturity was the highest contributors to D2 values. Two clusters consisting of six genotypes have been judged as improvement programme on the basis of their intercluster distances and higher cluster mean values for the aforesaid four characters.
