Inventory and descriptions of wild grapevine (Vitis vinifera subsp. sylvestris) from Slovenia, Croatia and Bosnia and Herzegovina
The current study inventoried remaining populations of wild grapevine [Vitis vinifera subsp. sylvestris (Gmel.) Hegi] in territories of south-east Europe encompassing Croatia, Slovenia and Bosnia and Herzegovina. Morphological and genetic traits of wild grapevine specimens were evaluated. The inventory started in 2015, confirming several historical populations in eastern Adriatic regions. In addition, some new ones not recorded until now were discovered. During prospection, wild grapevines were found at six geographically distant locations in this territory. Each observed individual was considered to meet truly morphological criteria (dioecism and leaf morphology) for sylvestris. Eighty-two sylvestris individuals belonging to six populations and 23 cultivated grapevines have been analyzed at 20 nuclear simple sequence repeat (SSR) loci to detect genetic diversity. Principal coordinate analysis and model-based cluster analysis differentiated among wild and cultivated grapevines, highlighting clearly two different groups. The results demonstrated the high genetic diversity of wild grapevine, and the existence of hidden alleles that could be of interest for breeding programs. The study provides necessary information for conservation management and further characterization of wild grapevine.
