SSR MARKERS ANALYSIS OF THE SARDINIAN GRAPE GERMPLASM

Sardinia has an ancient history as a secondary grape domestication centre, having developed a wide variety of different Vitis cultivars that lasts nowadays. Our work focused on giving a molecular basis of identification, through SSR, over this large genetic pool as a conservation strategy to manage field collection at local level. A set of 146 accessions including local, national and international cultivars was adopted. The genotyping of the grape collection held in Sardinia revealed a relatively high genetic variation. Eleven groups of synonyms and unknown local accessions were identified. Information on duplicates and incorrect denomination is also provided.
