Disease resistant grapes
IGA is actively involved in the breeding of commercial varieties. In collaboration with the University of Udine, one of IGA's institutional founders, we have selected and patented ten winegrape varieties, with increased resistance against downy mildew. The resistant winegrapes have been generated by conventional breeding via hybridization of noble winegrapes (Sauvignon, Merlot, Cabernet Sauvignon) with introgression lines that contain major R genes introduced from wild American and Asian grapes.
Vivai Cooperativi Rauscedo, a world-leading grape nursery, is commercially distributing graftings of these resistant winegrapes.
We are in the process of patenting three additional varieties, one of which with thiol content higher that any Sauvignon clone. Registration in the National Italian Catalogue is expected to be completed by 2016.
IGA commits itself to exploit conventional breeding and new breeding technologies to improve traditional winegrapes for a more sustainable viticulture. IGA's vision on grapevine breeding is reported in two papers.
