Abstract

Grapevines denominated 'Refošk', 'Refosco', 'Teran' and 'Terrano have been cultivated in the area of western Slovenia, north-western Croatia and north-eastern Italy for centuries. Despite historical documents reporting the longstanding tradition of grapevine cultivation and winemaking, the denomination and origin of these varieties is still questionable. The aims of this work were to study the genetic identity and relationship of the grapevine accessions denominated 'Refošk', 'Refosco', 'Teran' and 'Teranno' that have been traditionally cultivated in Slovenia, Croatia and Italy. For this purpose, 9 SSR loci were analysed to fingerprint 53 accessions with denominations or similar true-to-type morphologies of 'Refošk' and 'Teran'. The grapevine variety 'Refošk' cultivated in Slovenia and most accessions denominated 'Teran' in Croatia showed identical genotypes in all analysed SSR markers, and can therefore be used as synonyms. Five accessions showed identical genotypes to 'Refosco dal peduncolo rosso' variety, however five other genotyped accessions suggested individual profiles, and can be characterized as clonal mutants of true-to-type 'Refošk'/'Teran'. Accessions 'Sladki Teran' and 'Ref5/31' shared 56 % and 61 % of the alleles with true-to-type profiles of 'Refošk'/'Teran' and their parentage analysis strongly suggested a full-siblings relationship. Obtained results contribute to the understanding of the genetic diversity of grapevine varieties cultivated in this part of Europe.
