Members of the primary gene pool of the chickpea, including 38 accessions of Cicer arietinum, six of C. reticulatum and four of C. echinospermum grown in India were investigated using 100 SSR markers to analyze their genetic structure, diversity and relationships. We found considerable diversity, with a mean of 4.8 alleles per locus (ranging from 2 to 11); polymorphic information content r...
