Abstract: Forty seven rice bean genotypes were analyzed for genetic divergence which resulted in nine clusters having maximum inter-cluster distance between clusters III and IX and least between clusters V and VIII. Maximum intra-cluster distance was exhibited by cluster II followed by cluster I. Putative lines selected were from cluster II (JRB 08-6, JRB 08-6-1 and JRB 07-4) for days to flower initiation, dry matter yield per plant, dry matter yield per plant per day, crude protein yield per plant and crude protein yield per plant per day; cluster VI (JRO 15-6, KRB 86-1 and JRB 07-35-3) for green fodder yield per plant, number of leaves per plant, plant height, days to 50 per cent flowering, number of branches per plant, green fodder yield per plant per day and leaf : stem ratio, and cluster IV (JRO 15-1, JRO 15-4 and JRO 15-3) for leaf area, stem diameter, root length, fresh root weight and dry root weight. These lines can be used as patents in different hybridization programmes to obtain maximum variation for further selection.
