Sažetak
The classic wine varieties are all Vitis vinifera L., which is native to Europe and Western Asia. However, the exact origin of Zinfandel, one of the most important red wine cultivars of the United States, has been a mystery to Americans ever since its arrival on the continent. Genetic results obtained by SSR molecular markers presented here support the hypothesis of a Croatian origin of Zinfandel, as well as a high degree of relatedness between Zinfandel and autochthonous Croatian cultivars. Based on allele frequency analyses of Greek, Italian and Croatian Vitis vinifera L. gene pools, and discovered cultivar relationships, the Croatian gene pool is the most likely source of Zinfandel. The parentage of cultivars Pošip bijeli and Plavac mali, supported by ampelographic analysis, has been confirmed at 25 SSR loci. The observed gene diversity of 77.7% reveals a substantial level of genetic variation in the Croatian population of cultivars and points to the significance of preservation of more than 100 unique genotypes found in Croatia today.
