Abstract: In the last years, the release of an increasing number of new cultivars from different breeding programs is resulting in an important renewal of plant material worldwide. However, local varieties constitute a source of genetic traits of interest. Thus, it is important to conserve and study this genetic pool in order to preserve morphological and phenological characters. In this work, a set of 7 previously-described microsatellite markers (SSRs) has been selected in order to study the genetic diversity of 50 apricot cultivars, including both traditional and new cultivars from different breeding programs in different countries. The analysis of the diversity was carried out using software R. The study of the genetic variability of the different genotypes has resulted in the identification of three synonymies. In addition, the genetic relationships among the accessions studied have been represented in a dendrogram. The presence of 6 cladistic groups shows a tendency of the breeding program. This information could be useful to clarify which genotypes have been used as parentals in them. We identified genetic structure in the group of the genotypes by different population genetic analyses. There is no clear population differentiation, which is consistent with the use of common parental genotypes in the different breeding programs since they share some objectives.
