Abstract

Fifty-five accessions of cv. Refošk from a clonal selection vineyard in the Karst district (Slovenia) were screened by 6 SSR markers in order to assess their uniformity. Two of the accessions showed different patterns (Clone 7 and Clone 50), while 53 accessions revealed identical SSR allelic profiles. Four of the uniform and the two different accessions were compared to 11 Refošk types from adjacent regions (Slovenia (Koper), Croatia and Italy) using 23 SSR markers. The SSR analysis revealed 7 identical genotypes (4 uniform Karst clones, one Italian and two Koper types), while three Koper (Slovenia) and three Italian types, as well as Teran from Croatia, showed genetic polymorphisms on an intra-varietal level. Clone 7, Clone 50 and Sladki Teran (Croatia) showed highly diverse genetic patterns from other types and should be considered different varieties. Comparative analysis allowed reliable construction of the predominant Refošk type grown in Slovenia.
