Research Project: Identifying Sources of Resistance to Wood-Canker Diseases in Grape Germplasm

Location: Crops Pathology and Genetics Research

Project Number: 5306-21220-006-06
Project Type: General Cooperative Agreement

Start Date: Sep 01, 2012
End Date: Jul 31, 2015

Objective:
Screen grape cultivars with the causal agents of Eutypa dieback, Esca, and Botryosphaeria Canker.

Approach:
Planting disease-resistant culitvars is a time-tested and sustainable approach to disease management. Based on field observations and published research on resistance to wood-canker diseases, we know that a range of resistance exists among commercial cultivars of almond and grape. We propose to improve screening assays for evaluating both commercial cultivars and USDA germplasm repositories for sources of disease resistance. Our approach is to screen plant materials from both commericial nurseries and the USDA-ARS National Clonal Germplasm Repository.
