Abstract:
In the present study, fifty seven rice genotypes were chosen for diversity analysis using principle component analysis. The whole experiment was executed at Research cum Instructional Farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, during Kharif 2020. Principal components with Eigen values greater than 1 and variance level greater than 6 level is perceived to be the main PC. In this study, six components were displayed eigen values of >1 and presented cumulative variation of 79.59%. The first PC (24.70%) and second PC (17.34%) showed for cumulative variation 42.04%. The PC1 recorded 24.70%, although PC2, PC3, PC4, PC5 and PC6 displayed 17.34%, 12.90%, 9.93%, 8.55% and 6.17% variance respectively between the accessions for the characters in analysis. Genotypes IC125755, IC463062, IC121886, IC518800, IC377829, MTU-1010, DRR-42, Dagad Desi, Annada, IC593995, IC378553, IC74800X, IC203364, IC458046X, IC514243 and IC115726 were found to be promising and genetically divergent. As a result, these genotypes might be used in the hybridization programme to develop transgressive segregants.
