In order to identify grape varieties from Liguria (north-western Italy), 51 accessions (major, minor and neglected cultivars) were compared to those present in the grape collections of the neighbouring regions. Synonyms were confirmed by SSR markers (9 loci). Only 36 unique genetic profiles were found within grapes from Liguria, demonstrating the occurrence of synonyms with cultivars either from the same region or from other grape growing areas. Six evident misnames were found as well as homonyms. Four unexpected synonyms provided an opportunity to trace the likely origin and/or the movement of ancient cultivars, including ‘Vernaccia di San Gimignano’.
