Abstract: Genetic diversity of 62 genotypes of irrigated rice originating from BRRI, IRRI and China were studied through Mahalanobis D²statistic. The genotypes were grouped into five clusters. The cluster II and IV contained the highest number of genotypes (16) and the cluster I contained the lowest (7). The highest intra cluster distance was noticed for the cluster I and the lowest for cluster III. The highest inter cluster distance was observed between cluster I and cluster IV followed by cluster I and cluster V, cluster I and cluster III, cluster III and cluster IV and lowest between cluster IV and cluster V. The highest cluster means for yield and other three yield contributing characters are obtained from cluster I, six highest and two second highest means for yield contributing characters are found in cluster III but the lowest cluster mean for yield. Therefore more emphasis should be given on cluster I for selecting genotypes as parents for crossing with the genotypes of cluster III, which may produce new recombinants with desired traits.
