A study conducted at Instructional cum Research Farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur Chhattisgarh, to estimate the genetic diversity on 23 Hybrid rice genotypes using 18 microsatellite (SSR) markers, out of which fourteen SSR markers were found to be most informative for distinguishing the parental lines. Three rice CMS lines and twenty-three restorer lines used as parents in this study. Fourteen markers that were selected for the parental polymorphism study were: RM 517, RM 307, RM 228, RM 335, RM 251, RM 484, RM 09, RM 288, RM 302, RM 410, RM 444, RM 506, RM 411 and RM 535. The results shown in the study that considerable amount of genetic variability was present in the experimental material. Molecular markers like microsatellites (SSR’s) markers should be used in the studies to have a better understanding of parental polymorphism in the genetic materials and thus helpful for the exploitation of heterosis.
