Abstract: Assessment of genetic divergence using Mahalanobis D2 statistics was carried out among 46 rice genotypes including high yielding local and advanced breeding lines grown in Zn-deficient soil. The genotypes were grouped into seven clusters. Cluster I had the highest number of genotypes (Twenty one) followed by Cluster II (Nineteen) and Cluster V with two genotypes. Other cluster were found to be monogenotypic. Cluster IV showed highest intercluster distance from Cluster VI which was immediately followed by Cluster III and Cluster VII. Highest intracluster distance was observed in Cluster V and lowest in Cluster I. The desirable yield and its contributing traits were distributed mainly in Cluster III followed by Cluster VII and Cluster I. The genotypes within Cluster III, VII and I may be used as parents in hybridization programme to develop high yielding line ideal for Zn-deficient soil.
