Ampelographic and genetic characterization of Croatian grapevine varieties

Before the Phylloxera (Daktulosphaira vitifoliae) crisis in Croatia more than 400 grape varieties were under cultivation. Today their number is drastically decreased. Recently, many efforts in the preservation of grapevine biodiversity were undertaken: detailed inventory of varieties in different wine-growing regions, establishing of national and regional collections and their systematic ampelographic and genetic characterisation. This paper shows results of multiannual ampelographic and genetic research concerning Croatian grapevines considered as autochthonous varieties. After identification, many synonyms and homonyms were detected and unique genotypes were selected. Basic data of them are shown: description (according to OIV descriptors) and genetic profiles (9 SSR loci), growing area and status of vulnerability. Also, genetic relationship ased on the shared allele distance is computed from SSR data. Results show certain level of similarity among varieties, and classify Croatia as important gene-pool in Europe. Some additional accessions which were detected and introduced into collections recently are still being investigated and characterized so that the here presented list of Croatian native grapevine cultivars is not final.
