Genetic diversity of 62 chickpea accessions was studied using 8 ISSR and 11 RAPD primers. In the study RAPD primers detected more polymorphism (98%) than the ISSR primers (80%). Genetic diversity index was high (0.73 for ISSR and 0.85 for RAPD) for each of these marker systems. Cluster analysis performed from both separate and combined data of RAPD and ISSR markers using SPSS software package. Jaccard’s similarity coefficient for 62 chickpea genotypes was 0.65. Cluster analyses based on combined data generated a dendrogram that separated genotypes into 11 clusters. Four clusters contained only one genotype showing the genetic uniqueness of these accessions. The studied chickpea collection has been proved to constitute a rich source of biodiversity as revealed by RAPD and ISSR markers. Crossing between distantly related genotypes is expected to yield more vigorous plants constituting much of the different traits contained in the two parental lines.
