Abstract: The experiment was conducted with Twenty-five rice genotypes during Kharif 2022 in a Randomized Block Design with three replicationsat Research and Educational farm, Department of Agriculture Botany, College of Agriculture, Dapoli to study the genetic divergence for yield and quality traits. Genetic divergence calculated by Mahalanobis’s D2 statistic grouped twenty-five rice genotypes into six clusters. Out of six clusters, cluster II was the largest (9 genotypes) followed by cluster III (5 genotypes), cluster IV (5 genotypes), cluster I (4 genotypes), while remaining two clusters had one genotype each. The high intra-cluster value was recorded in cluster IV followed by cluster II, cluster III, cluster I, thus indicating that the genotypes constituted in high intra-cluster value clusters might have different genetic constitution. The inter-cluster values were maximum in cluster V and VI followed by cluster III and VI, cluster I and V, cluster II and VI indicating significant difference between these clusters. Hence, the genotypes included in these clusters may be used in hybridization programmes.
