UCD Professor/Geneticist to Retire June 29 June 02, 2021
University of California, Davis (UCD) professor and geneticist Dr. Andrew Walker will retire June 29 after more than 30 years on the Department of Viticulture and Enology faculty and as a winegrape breeder. Given the long-term nature of the grape breeding process, it s not surprising that some of Walker s more significant breeding projects came to fruition later in his career the release of five nematode resistant rootstocks in 2009, and the 2020 official release of five new winegrape varieties resistant to Pierce s Disease (PD). Reflecting the reality of his work, Walker titled one of his recent lectures, 30+ Years of Grape Breeding and Just Getting Started. With additional winegrape cultivars in development in the Walker Lab being bred for both PD resistance and powdery mildew resistance, important new grapevine materials will continue to become available well after he retires.
