Research Project: Developing PVX, PVY, and Potato Cyst Nematode Resistance Using Molecular Markers to Identify Resistant Material in Breeding Programs

Location: Small Grains and Potato Germplasm Research

Project Number: 5366-21000-032-03-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 14, 2011
End Date: Sep 30, 2013

Develop Potato Virus Y (PVY) and nematode resistance by 1) screening advanced breeding clones and released varieties with molecular markers for Potato Virus X (PVX) and Potato Cyst Nematode (PCN) (Globodera pallida); 2) bioassay characterization of resistant clones/varieties for PVX, PVY, and PCN; 3) make crosses from resistant parents.

Multiple entries from North America potato breeding programs will be screened for PVX and PCN resistance using molecular markers and bioassay data. Bioassays of putative PVX, PVY, and PCN resistant clones will be done at the USDA, Agriculture Research Service (ARS) in Aberdeen, Idaho for PVX and PVY, and at Moscow, University of Idaho for PCN resistance. Resistant clones/varieties will be used in a crossing block to generate a virus and nematode resistant population for further screenings/evaluation.
