RAPD patterns were studied using twenty photoperiod Sensluve accessions of rice for assessing genetic diversity among them. Out of 60 decamer random primers used, six primers (OPE 9, OPG 14, OPJ 14, OPK 12, OPN 18 and OPO 15) revealed polymorphic DNA banding pattern. All the genotypes were uniquely distinguished and were clustered into six distinct clusters based upon similarity index represented by the ratio of common bands and total number of bands for each pair of all the accessions. Maximum number of genotypes were found to occur in clusters Nand Veach having five genotypes followed by the cluster I which comprised four genotypes. The cluster II was monogenotypic.
