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).
