In the present study, forty-nine rice genotypes consisting of high yielding rice genotypes were raised at Regional Research Sub Station, Chakdah, during Kharif-2014 to evaluate and identify diverse genotypes for twenty yield and yield attributing characters using the D2 statistic. Among six clusters, cluster-II was the largest with 28 genotypes followed by cluster-I and cluster-III with 10 and 5 genotypes respectively and cluster-IV, V & VI each with two genotypes. Highest inter cluster generalized distance (1957.68) was between cluster- IV and cluster-V followed by cluster-III and IV (1954.27), cluster-I and IV (1779.21) and cluster-II and IV (1549.69) specifying that genotypes included in these clusters were genetically diverse and would give rise high heterotic response, while the lowest inter cluster was 587.86 found between cluster-I and cluster-V indicating close relationship among the genotypes included in these clusters. The intra cluster distance was maximum in cluster-III (684.04) followed by Cluster-II (646.28) and cluster-I (630.83) indicates hybridization of genotypes within this cluster may result in good cross combinations. Among the twenty traits studied, maximum contribution was made by harvest index and (27.466%) and seed yield per plant (26.105%), these characters may be given importance during hybridization programme.
