Description Knowledge of the molecular genetic variation of the accessions of core collections will be important for their
efficient use in breeding programs, and for conservation purposes. The present study was undertaken for
genotyping the part of the USDA chickpea core collection (Hannan et al 1994) with 20 microsatellite or simple
sequence repeat (SSR) markers. In addition to understand the molecular diversity in the core collection, the
genetic relationship was studied. A total of 376 accessions from the USDA chickpea core collection were
genotyped. Twenty SSR markers revealed a total of 388 alleles among the 376 accessions. In the USDA core
collection, the shared allele frequency (SAF) varied from 7.5% to 47.5% with an average of 21.6%. In the present
study, the structure of the population was determined by using K=4 based on model-based (Bayesian) clustering
algorithm.
