SSR based Molecular diversity associated with Peanut bud necrosis disease (PBND) resistance were detected in a set of 15 groundnut genotypes using 9 putative SSR primers. Out of 45 bands amplified from 9 primers, 29 were found polymorphic (64.4%).The Polymorphic information content (PIC) ranged from 0.0 (PM-15) to 0.49 (PMC-588). Cluster analysis grouped the genotypes into two main clusters with 0.12% similarity. Among all genotypes highest similarity (0.80) was found between TMV-2 and R-2001-2. But, the grouping was based on the origin of genotype rather than resistant alleles.
