| Abstract:
Based on the SSR analysis of more than 300 different grapevine cultivars and twenty different genotypes of Vitis silvestris we concluded that there is no clear differentiation between V. silvestris and V. vinifera possible. Moreover most alleles found in Vitis silvestris are still present in Vitis vinifera. Some varieties of today's use still show allele length typical for Vitis silvestris. Despite some characteristic alleles Vitis silvestris genotypes posses very heterozygous SSR profiles due to their huge population in former times. Inbreeding of V. vinifera resulted in varieties still appreciated for viticulture nowadays. We want to propose the origin of cv. Traminer from hybridization of two Vitis silvestris genotypes (type Gmelin) and therefore this variety represents a domestificated wildtype. Considering the frequent parentage of Traminer (and Traminer-like cultivars) we can estimate the importance of this variety for the development of many European cultivars. Furthermore there exists a very close relationship between Traminer and Pinot. Several Pinot related varieties as Chardonnay, Auxerrois, Melon and Aligote derived by hybridization of Pinot x Heunisch. Heunisch (Vinum hunicum) is the first name of a grapevine cultivar mentioned in ancient literature, which is cultivated still today. | |
