Research Project: Identification of Germplasm with Resistance to Potato Cyst Nematodes

Location: Horticultural Crops Research

Project Number: 2072-22000-043-40-I
Project Type: Interagency Reimbursable Agreement

Start Date: Aug 1, 2019
End Date: Jun 30, 2021

1. Identify germplasm in Chile and Peru to screen for resistance to potato cyst nematodes. 2. Screen material for resistance to Globodera rostochiensis, G. pallida, and G. ellingtonae.

Work with Servicio Agricola y Ganadero (SAG) in Chile and the International Potato Center (CIP) in Peru, to select appropriate material for screening and to facilitate the shipment of this material to the U.S. for screening against potato cyst nemotodes (PCN). By working with two different countries that encompass both of the proposed origins of potato (Solanum tuberosum) the chance of finding material with resistance to one or all PCN is increased. Additionally, S. tuberosum ssp. andigena, which provided the source of the H1 gene, originates from the Andean region of Chile indicating that other untapped sources of resistance may exist in this diverse germplasm.
