Description The present investigation was undertaken to study the 54 rice genotypes to estimate the diversity, among selected rice genotypes for yield and its component characters. The experiment was carried out during Kharif, 2020, in a randomized block design with three replications at the Indian Institute of Rice Research, Rajendranagar, Hyderabad voluntary center (Kampasagar), in Telangana State. The data was collected on characters viz and salt-tolerant score 0-9 scale. The 54 genotypes of rice were grouped into twelve clusters. Clusters with their genotypes are presented in. Cluster I had 15 genotypes, Cluster II had 13 genotypes, whereas Cluster III had 4 genotypes Cluster IV, V had 4 genotypes and cluster VI had 6 genotypes cluster VII had 1 genotype cluster VIII had three genotypes cluster Ⅸ, Ⅹ, Ⅺ had 1 genotypes cluster Ⅻ had 3 genotypes Highest inter-cluster distance was exhibited between clusters VIII and Ⅺ. and lowest cluster divergence found between the clusters Ⅳ and VII Greater the distance, wider the genetic diversity among the genotypes of those clusters. For high heterotic recombinants performing genotypes would be used as parents in the recombination breeding program.
