Six isolates of chickpea collar rot fungus of Sclerotium rolfsii were collected from different locations of Maharashtra were investigated for genetic diversity under present experiment. We employed five SSR of MB- series to construct a genotype-specific DNA fragment profile of field isolates of this fungus. The PCR amplified product of each primer was resolved on 10 % Polyacrylamide gel electrophoresis. The 5 SSR primers screened produced a total of 60 reproducible and scorable amplicons. The size of amplicons produced ranged from 115bp to 800bp. The percentage polymorphism generated by the SSR markers was 77.6% among all the 6 isolates of Sclerotium rolfsii. The result from the UPGMA based dendrogram generated for Sclerotium rolfsii isolates revealed that they were divided into two main clusters, Cluster-A and B which were further subdivided into sub-clusters. The isolates in the two clusters have an overall Jaccard's similarity coefficient of 35%. The similarity coefficient range varied from 0.27 to 0.83. The SSR markers suggest that there is genetic differentiation among the population.
