Twenty rice genotypes which recorded resistant and moderately susceptible reaction against rice leaf folder were characterized by using SSR markers. Out of eleven primers of SSR markers tested, seven primers were found to be polymorphic in nature. A total of 123 amplified bands were seen with 78 % polymorphism with the primers RM 3691, RM 600, RM 14 and RM 228. And it was also observed that all the bands were in the range of 100 bp to 1000bp. A clear variation in the banding pattern was observed among the resistant and susceptible genotypes with the primer RM 3691. The Jaccard’s similarity values ranged from 0-89 % indicating the presence of wide range of genetic diversity. The dendrogram showed variable degree of relationship among the genotypes. The resistant and moderately susceptible genotypes were grouped into two different clusters indicating that they were significantly different at molecular level also. In cluster-I, INRC-3021 and W1263 were very closely related and in cluster-II, NLR 145 and Sri Satya were closely related with the similarity index of 86 and 89 %, respectively.
