Three molecular markers, including start codon targeted (SCoT) polymorphism, directed amplification of minisatellite-region DNA polymerase chain reaction (DAMD-PCR), and inter simple sequence repeat (ISSR) markers, were compared in terms of their informativeness and efficiency for analysis of genetic relationships among 38 accessions of eight annual Cicer species. The results were as follows: (1) the highest level of detected polymorphism was observed for all three marker types; (2) the rate of diversity for the three marker techniques was approximately equal, and the correlation coefficients of similarity were statistically significant for all three marker systems; (3) the three molecular markers showed relatively similar phylogenetic grouping for examined species. Diversity analysis showed that Cicer reticulatum is the closest wild species to the cultivated chickpea, and this finding supports the hypothesis that C. reticulatum is the most probable progenitor of the cultivated species. C. bijugum, C. judaicum, and C. pinnatifidum were clustered together, and in other clusters C. yamashitae and C. cuneatum were grouped close together. To our knowledge, this is the first detailed comparison of performance among two targeted DNA region molecular markers (SCoT and DAMD-PCR) and the ISSR technique on a set of samples of Cicer. The results provide guidance for future efficient use of these molecular methods in genetic analysis of Cicer.
