Research Project: Identifying Sources of Resistance to Wood-canker Diseases in Pistachio Germplasm

Location: Crops Pathology and Genetics Research

Project Number: 2032-21220-006-08-A
Project Type: Cooperative Agreement

Start Date: Sep 1, 2012
End Date: May 31, 2017

Screen pistachio cultivars with the causal agents of Panicle and Shoot Blight of Pistachio.

Planting disease-resistant cultivars 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. In pistachio, the entire acreage of which consists of a single, suceptible cultivar, newly-released cultivars offer an opportunity for identifying new sources of resistance. Our approach is to screen plant materials from both commercial nurseries and the USDA-ARS National Clonal Germplasm Repository.
