Twenty-five scented rice genotypes were grouped into six different clusters. Cluster I consisted of six genotypes followed by cluster II consist of seven genotypes, clusters III consist of eight genotypes, cluster IV consist of one genotypes and cluster V consist of one genotypes and cluster VI consist of two genotypes. The highest intra cluster distance for yield traits was found in cluster VI (301.94). The lowest values for intra cluster distances was recorded for cluster IV and V (0.00).The maximum inter cluster distance (D2-values) was found between cluster IV and I (4463.46), followed by cluster II and cluster I (3265.73). Length of main panicle had very low contribution (0.33%) towards total divergence whereas number of seeds per panicle had very high contribution (39.67%) toward total divergence and in quality traits kernel length after cooking had highest (37.33%) contribution.

Key words: Scented Rice, Intra Cluster Distances, Inter Cluster Distance, Divergence, quality traits.
