  • Six nuclear microsatellite loci (VVMD 5, VVMD 7, VVMD 27, VrZAG 62, VrZAG 79 and VVS 2) were chosen to study the differentiation of 313 grapevine cultivars offi cially authorized for wine production in Portugal (Portaria nº 428/2000, Diário da República nº 163, 17th July 2000).

    These loci were found to be highly informative and therefore constitute a useful marker set for the discrimination of the targeted cultivars. This study allowed for the detection of 244 distinct genotypes as well as for the identifi cation of synonyms in 40 cultivars, where 2 to 6 (synonymous) cultivars represent seventeen genotypes. The remaining 29 cultivars are distributed in 11 distinct sets, where each set displays identical SSRs profi les. However, these should be considered as distinct cultivars considering that these differ in berry colour. Taken together, the results of this work will contribute to improve the management of the Portuguese Grapevine National Collection as well as give a good technical support for the update of the list of cultivars offi cially authorized for wine production in Portugal (Portaria nº 428/2000). Furthermore, it will also be a useful for the control of plant material in the future.

    The SSR database will be available at the web page of Instituto Nacional de Recursos Biológicos (INRB) www.inrb.pt
