Research Project: Identifying Novel Potato Germplasm with Resistance Against Cyst Nematode and Dickeya Pathogens

Location: Emerging Pests and Pathogens Research

Project Number: 8062-22000-022-23-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2021

Objective:
Screen a group of wild potato species to identify new potato germplasm that confer resistance to potato cyst nematodes (Globodera rostochiensis and G. pallida) and Dickeya blackleg and soft rot disease.

Approach:
1. Use pot or canister assay to screen wild potato species for resistance against G. rostochienisis Ro2 and G. pallida. 2. Use a tuber maceration assay to screen wild potato species for resistance against Dickeya.
