To estimate genetic diversity within and between 10 interfertile Cicer species (94 genotypes) from the primary, secondary tertiary gene pool, we analysed 5,257 DArT markers 651 KASPar SNP markers. Based on successful allele calling in 2,763 624 that are polymorphic genotypes pools were analyzed further. STRUCTURE analyses consistent with 3 cultivated populations, representing kabuli, desi pea-shaped seed types, substantial admixture among these groups, while two wild populations observed using AMOVA was used to partition variance hierarchical sets of landraces at both geographical level, 61% variation found species, 39% species. Molecular high (39%) compared present material (10%). Observed heterozygosity higher than for each linkage group. Our results support Fertile Crescent as center domestication diversification chickpea. The collection study covers all three regions historical chickpea cultivation, highest region. Shared alleles different suggest possibility flow or incomplete lineage sorting could indicate complicated patterns divergence fusion taxa past.
