Nematode-Resistant Grape Rootstocks
Global Plant Genetics represents specialist grape rootstock genetics developed to address key challenges in modern viticulture. Our focus is on nematode-resistant grape rootstocks that support vineyard performance in regions where soil health, pest pressure, and regulatory change are critical considerations.
As representative of grape rootstocks developed by the University of California, Davis, GPG manages the licensing and protection of GRN1 and GRN3 rootstocks across Europe. These rootstocks enable wine and table grape producers to establish vineyards in nematode-affected soils without soil sterilisation, while also providing Phylloxera resistance. In parallel, the GPG Grape team is pleased to bring five UC Davis Pierce’s Disease–resistant winegrape varieties to Europe – a groundbreaking release that includes three reds (Camminare Noir, Paseante Noir, and Errante Noir) and two whites (Ambulo Blanc and Caminante Blanc), combining durable disease resistance with high fruit and wine quality for growers operating in PD-prone regions.
