The field experiment was conducted during kharif season (August–November), 2018 to evaluate the available red rice genotypes for genetic diversity using K-means cluster analysis for grain yield, its components and cooking quality traits at the College of Agriculture, V. C. Farm, Mandya. University of Agricultural Sciences, Bengaluru, Karnataka, India. Multivariate analysis was carried out in RCBD with 2 replications to understand the nature and magnitude of genetic divergence among sixty-four red rice genotypes. The analysis of variance showed that significant variance was observed among genotypes for all the traits studied. Based on K-means cluster analysis, optimum number of clusters formed were nine. Maximum number of genotypes grouped in cluster III (15) followed by cluster IV (12). Maximum intra-cluster distance was shown by cluster I (55.79) and cluster IX (53.50) indicating wide genetic variation …
