A total of fifty five genotypes of gum cluster bean were evaluated for genetic divergence using Mahalanobis D2 technique in kharif season at two location. Maximum contribution of each character towards genetic divergence were showed by ten dry pod weight followed by seed to husk ratio, gum content in seed, number of seeds per dry pod, plant spread and length of dry pod contributed 99.00 % divergence. Using estimated D² values, 55 genotypes were grouped into 8 clusters using Tocher's method. In kharif condition (E1+E2), cluster IV was the largest involving 15 genotypes, whereas cluster III, VII, I, II and V involved 13, 09, 07, 06 and 03 genotypes respectively. The remaining clusters (VI and VIII) contained only one genotype each. The intra-cluster divergence ranged from 0 to 165.86. Cluster VII possessed the highest intra-cluster distance (D2=165.86), followed by cluster IV (D2=89.27), cluster V (D2=72.48), cluster III (D2=67.53), cluster II (D2=41.40) and cluster I (D2=32.59). The average inter-cluster distance was maximum between cluster V and VII (D²=407.30) followed by cluster VII and VIII (D²=385.80), cluster V and VIII (D²=372.06). Hence genotypes grouped under these clusters could be used for crossing if superior varieties are planned in the breeding development programme.
