Research Project: Immunity to Potato Cyst Nematodes

Location: Horticultural Crops Research

Project Number: 2072-22000-043-25-I
Project Type: Interagency Reimbursable Agreement

Start Date: Jul 1, 2017
End Date: Sep 30, 2018

1. Development of russet and processing types of potato that possess strong resistance/immunity to Potato Cyst Nematod (PCN). 2. Exploration of wild potato species for broad-spectrum resistance to Globodera.

New populations of potato representing unique individuals with the potential to be new varieties having PCN resistance will be generated following directed hybridizations in the greenhouse between PCN-resistant breeding clones and varieties (round, non-russet skinned) and long, russet-skinned breeding clones and varieties. Wild potato accessions showing a hypersensitive response (HR) phenotype in the infiltrated leaves will be further evaluated for nematode resistance for G. rostochiensis, G. pallida, and G. ellingtonae, respectively, using established protocols.
