Research Project: The Role of Host Resistance of Potato, Rotation and Trap Crops in Controlling Soilborne Pests and Pathogens of Potato

Location: Temperate Tree Fruit and Vegetable Research

Project Number: 2092-21220-002-11-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 22, 2014
End Date: Aug 31, 2019

Objective:
Identify cultivable plant species and potato that exhibit host resistance for certain pests and pathogens common in the Pacific Northwest and achieve a measure of control or eradication without the use of chemicals.

Approach:
Test different plant species and potato germplasm for host range against a panel of pests and diseases of the Pacific Northwest. Hosts should demonstrate egg hatching induction, but lack of successful parasitism and reproduction for nematodes, lack of successful initial inoculation events and propagation in the case of fungi. Host reistance in potato will be studied for use of molecular markers and/or genomic sequence providing aids to selection in traditional breeding programs.
