Abstract: A broad prospection of grapevine plants was carried out in northwest Spain and north of Portugal during the period from 2002 to 2009. It included zones located in Galicia as well as in the provinces of León, Zamora and Salamanca in Spain and the region delimited by the right side of the Douro river and the spanish border in Portugal. A total of 669 accessions were sampled, studied and identified, both by using the six microsatellite loci included in the OIV descriptors list, plus ampelographic characters. As a result of the study a total of 53 different grapevine varieties were identified. Most of them correspond to minor varieties that are present in the zone. In many cases the same variety was detected in both countries, although denominated with different names that are synonymous. The molecular markers that were analyzed are those included in the OIV 801 to 806 descriptors, and correspond to the following loci: VVS2, VVMD5, VVMD7, VVMD27, ssrVrZAG62 and ssrVrZAG79. Allele sizes of the studied varieties are recorded. Relationships among these varieties seem to be possible. Recommended priority names for the studied varieties both in Spain and in Portugal are listed, in order to avoid misidentifications and reduce the incidence of homonymies.
