Location: Crop Diseases, Pests and Genetics Research
Project Number: 2034-21220-007-015-R
Project Type: Reimbursable Cooperative Agreement
Start Date: Jul 1, 2018
End Date: Dec 31, 2021
Objective:
This proposal seeks to determine the virulence (level of disease caused by a given individual) diversity of Xylella fastidiosa (Xf), the causal agent of Pierce's Disease (PD) of grapevine in California, as part of an integrated management program by enhancing host resistance to PD. This will be accomplished by evaluating disease incidence and severity on susceptible hosts of Xf isolates collected throughout California. This information will be used in breeding programs to identify durable sources of disease resistance.
Approach:
The objectives of the proposal will be met by 1) evaluating the virulence diversity of Xylella fastidiosa isolates from California and 2) evaluating known sources of PD resistance against diverse isolates of X. fastidiosa.
