摘要：The evolutionary history of Salix genus and the relationships among the species and accessions are controversial and not well understood. In this study, SRAP markers were used to establish the level of genetic relationships and polymorphism across eleven clones of two Salix species collected from 9 different regions of West Azarbaijan province. The SRAP analysis with 22 anchored primers generated 116 scorable loci, of which 84 were polymorphic (77%). Jaccard similarity coefficient ranged from 0.22 to 0.74. The Complete linkage cluster was performed and dendrogram drawn by help of NTSYS pc 2.02 software which revealed three main clusters. According to our results, there is a relatively high genetic distance across Salix clones in West Azarbaijan province of Iran. Furthermore, it could be inferred that SRAP markers are suitable tools for the evaluation of genetic diversity and relationships within the Salix genus.
