Abstract: A two year field study on the genetic divergence among 60 traditional rice (Oryza sativa L.) germplasms promising for red and laterite tract of West Bengal, India and two released varieties was conducted using Mahalanobis D2 statistics. The 62 genotypes were grouped into eight clusters where, cluster I was largest containing 38 genotypes followed by cluster II with 9 genotypes. Based on the inter cluster distance, the entries viz. Pankey, 60-Chali, Dudheswar, Sitabhog, Kalonunia, MTU-7029, Netaisail, Bhutmuri (Kelias) were selected which could be intercrossed to obtain high heterotic effect and also to recover desirable transgressive segregants.
