Abstract: The Rice germplasm provide with ample of genetic diversity and a treasury of valuable genes. It is a rich pool of important genes that plant breeders can exploit for crop improvement. Principal components with eigen values greater than 1 and variance level greater than 4 level is perceived to be the main PC. In this study, eight components exhibited Eigen values of >1 and showed cumulative variation of 75.22%. The first PC (15.83%) and second PC (15.33%) showed for cumulative variation 31.36%. The PC1 recorded 15.83%, although PC2, PC3, PC4, PC5, PC6, PC7 and PC8 displayed 15.33%, 12.64%, 9.03%, 7.4%, 5.91%, 4.61% and 4.27% variance respectively between the accessions for the characters in analysis. Genotypes Saraiphool, MTU 1010, Zinc rice-2, Chaptimathyala, Bora, Korma, R-RKM-1, Kalajeera, Jauphool, Tiltaturi and Parwatkala were found to be promising and found to be genetically divergent. Hence, these genotypes could be utilized in the hybridization programme to produce transgressive segregants.
