Abstract:
The genetic diversity among thirty six chickpea genotypes was assessed by morphological and molecular studies. The Mahalanobis D² statistic grouped 36 genotypes into six clusters with the largest cluster comprising 20 genotypes. 100 seed weight contributed the most to genetic divergence. Out of 31 SSR markers used in the study, 28 were found to be polymorphic. A total of 107 alleles were detected across 36 chickpea genotypes with an average of 3.4 alleles per locus. Polymorphic information content ranged from 0.52 to 0.84. DICE similarity coefficient classified the genotypes into 4 clusters of which cluster I was the largest with 14 genotypes. The genetic similarity coefficient ranged from 0.03 to 0.78.
