Ry_chc Confers Extreme Resistance to Potato virus Y in Potato.

ABSTRACT: The Potato virus Y (PVY) is responsible for huge economic losses for the potato industry worldwide and is the fifth most consequential plant virus globally. The main strategies for virus control are to limit aphid vectors, produce virus-free seed potatoes, and breed virus-resistant varieties. The breeding of PVY-resistant varieties is the safest and most effective method in terms of cost and environmental protection. Ry_chc, a gene that confers extreme resistance to PVY, is from S. chacoense, which is a wild diploid potato species that is widely used in many PVY-resistant breeding projects. In this study, Ry_chc was fine mapped and successfully cloned from S. chacoense accession 40-3. We demonstrated that Ry_chc encode
