Identity, synonymies and homonynies of minor grapevine cultivars maintained in the portuguese ampelographic collection

Abstract

Nineteen SSR were used to genotype twenty eight accessions from Portugal, France, Greece, and Spain, preserved at the Portuguese National Ampelographic Collection (international code - PRT 051). Some of these accessions have never been genotyped and are minor, underused cultivars. Eight cases of synonymies and one case of homonymy were detected. The identification of synonyms in underused cultivars increases de possibility of obtaining adequate plant material for certification purposes and commercialization. The new unique genotypes identified in this work will be proposed for inclusion in the list of authorized cultivars for wine production in Portugal. No certified plant materials exist for these cultivars.
