This study describes the genetic relationships among 24 Iranian grape cultivars using inter simple sequences repeat (ISSR) and morphological markers. Eleven ISSR primers generated 110 polymorphic bands which were used in the analysis. The lowest genetic similarity was observed between ‘Ghzl uzum Tabriz’ and two cultivars including ‘Goye maleki’ and ‘Maie mev’ (0.38) while the highest genetic similarity was found between ‘Ghzl uzum Tabriz’ and ‘Ghara shira’ (0.70). The grape cultivars were grouped into four clusters. In the morphological analysis, which included 14 traits, 9 were polymorphic. The genetic similarity coefficient ranged from -0.67 to 0.97 for this morphological analysis and the resultant dendrogram revealed three main clusters. ISSR markers could detect high polymorphism among the cultivars and the ISSR method was shown to be a suitable means of determining genetic diversity in future conservation and breeding programs.
