Research Project: Development and Release of Golden Nematode Resistant Potatoes

Location: Emerging Pests and Pathogens Research

Project Number: 8062-22000-022-027-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2020
End Date: Jul 31, 2025

Objective:
The objectives of this cooperative research project are to develop and release improved potato cultivars with resistance to multiple pathotypes of the golden nematode (Globodera rostochiensis), develop profiles of new resistant cultivars to aid grower acceptance, and provide disease-free tissue culture plantlets of resistant cultivars.

Approach:
1. Crosses of potato clones will be made to generate populations that are segregating for resistance to multiple pathotypes of the golden nematode and improved horticultural and marketing characteristics. 2. Potato clones will be evaluated for nematode resistance and selected for downstream evaluations. 3. Resistant potato clones will be subjected to an extensive evaluation scheme and selected for improved yield, desired marketing characteristics, and disease resistance. 4. Disease-free tissue culture stocks will be developed and distributed to commercial seed growers for final multiplication as necessary to meet grower demands.
