Magna Greacia has always been considered to be the oldest Italian wine-growing region, rich of autochthonous varieties, some of them well-known and appreciated around the world. The study of genetic variability of 140 cultivars from Basilicata, Calabria, Campania, Puglia, Sicilia regions and Greece, by 18,000 SNP (Single Nucleotide Polymorphism) molecular markers, highlighted that they are strongly related each other by parentage relationships, resulting into a complex pedigree. Aglianico, Montonico Bianco e Sangiovese are the varieties with the highest number of relationships. This result states that the use of elite cultivars in breeding programs occurred, shaping the grapevine ampelographic platform of Southern Italy.
