Research Project: Development of New Molecular Markers to Facilitate Selection for Pierce’s Disease Resistant Grapevines in California

Location: Crop Diseases, Pests and Genetics Research

Project Number: 2034-22000-012-09-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Oct 1, 2016
End Date: Jun 30, 2019

1. Screening and identification of Pierce’s disease (PD) resistant progeny in b43-17 and N18-6 hybrid populations. 2. Continue developing next generation biomarkers and linkage map for PD resistance in South East US grape populations.

1. Characterize disease severity and Xf titers in greenhouse experiments to identify breeding lines with the highest level of resistance possible. 2. Evaluate molecular markers for co-segregation with PD resistance.
