Molecular and morphological characterization of marginal Vitis vinifera material in Vinhos Verdes DOC region
Abstract
In Vinhos Verdes DOC Region, production and labeling of wines with indication of “sub-region” is limited to the use of 15 different cultivars (Ministerial Order 668/2010). Nevertheless, in the beginning of the XXth century there was reference to around one hundred different names of grapevine cultivars in the restricted area of same municipalities of Vinhos Verdes Region.
A broad prospection throughout all grapevine material with different characteristics of Vinhos Verdes Region was carried out and all the samples were installed in a viticulture center: “Estação Vitivinícola Amândio Galhano” (EVAG) in the middle of Vinhos Verdes DOC Region.
A total of eight accessions were sampled and studied using the six microsatellite loci included in the OIV descriptors list (OIV 801 to 806 descriptors) that correspond to VVS2, VVMD5, VVMD7, VVMD27, ssrZAG62 and ssrZAG79 loci, plus ampelographic characters, including all qualitative and quantitative descriptors that belong to the “Primary descriptor priority list”.
The results of this study contribute to the characterization and valorization of minor Vinhos Verdes autochthonous cultivars. Moreover, elucidation of possible synonymies with other cultivars with similar names was achieved.
