Research Project: Immunity to Potato Cyst Nematodes

Location: Emerging Pests and Pathogens Research

Project Number: 8062-22000-023-007-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jul 1, 2022
End Date: Jun 30, 2023

The goal of this project is to identify clones from a group of wild potato accessions that confer resistance against potato cyst nematodes and determine if the resistance observed in the confirmed resistant clones may be mediated by a resistance (R) gene(s). The identification of new resistant germplasm would allow quick transfer of resistance genes to current potato cultivars, thereby providing effective tools for the control or eradication of potato cyst nematodes in the U.S.

Objective 1: We have established plant growing conditions that allow a good production of tubers from wild potato species. Once tubers are collected, pot bioassay test will be conducted in the Dandurand lab (U. of Idaho) and the Wang lab (Cornell University, NY) using standard protocols that are routinely performed in both labs. In the bioassay test, ‘Russet Burbank’ and ‘Desiree’ (susceptible cultivars) as well as ‘Innovator’ (resistant cultivar) will be included as controls and a final cyst count will be used to determine the level of resistance for each clone.
