Ampelographic and DNA Characterization of Local Grapevine Accessions of the Tuscia Area (Latium, Italy)

Abstract

The presence of local vines in the Tuscia area (Latium region, Italy) was documented by historical sources. Ampelographic and molecular characterization (35 morphological descriptors and 16 microsatellite loci) was carried out on accessions belonging to the most frequently mentioned local vines. SSR markers have enabled us to distinguish cases of local synonymy and microsatellite profiles have permitted comparison with previously reported profiles indicating synonymy and divergence with vines in other collections. Ampelographic traits showed that some accessions of the same genotype differ in minor characteristics that can have a role in clonal evaluation.
