Due to the necessity for traditional grape varieties to be chemically treated 6-16 times each year, there was a need to create more resistant varieties. The main goal was to combine the good resistance of American cultivars to fungi with the high quality of European cultivars. In 2016, after 15 years of research by the University of Udine and the IGA (Applied Genomic Institute – Italy) the first ten resistant vines were legally registered and authorized: Fleurtai, Soreli, Sauvignon Kretos, Sauvignon Nepis, Sauvignon Rytos, Cabernet Eidos, Cabernet Volos, Merlot Khorus, Merlot Kanthus, and Julius.
