Grapevine (<i>Vitis vinifera</i> L.) varietal assortment and evolution in the Marche region (central Italy)

Italy is one of the richest countries in terms grapevine varietal assortment, and Marche region central has an ancient winegrowing tradition. Increasing interest autochthonous varieties prompted efforts to recover identify local minor germplasm also this region, search for pedigree relationships determine evolution assortment. In present study was done using nuclear chloroplast microsatellite markers SNP from Vitis18kSNP chip. Eighteen new genotypes were found, which seventeen belonged well-known, less known even unknown vines found be specific region. The rearranged highlighted complex intertwining between varieties. Second-degree derived. Some have increased number parent-offspring related members Garganega, Sangiovese, Crepolino/Visparola Sciaccarello, are already recognised as founders or recurrent parents many Italian cultivars. shown a key variety having played role parent grandparent, explained by presence genotype times. Surprisingly, Semidano, well-known Sardinian variety, clear grandparent three varieties, testifying its Incrocio Bruni 54 confirmed offspring Sauvignon Verdicchio, declared breeder. parentage Lacrima completed: spontaneous cross Nera Rada Aleatico.A dendrogram genetic similarity clearly resembled groups defined with reconstruction it gave indication excluded strictest links.
