Assessing Virus Resistance in New York Grown Potato Varieties and Breeding Lines: Disease Resistance as an Integral Part of Pest Management

Abstract

In 2002, two viruses that are part of an emerging potato disease complex (tuber necrosis) were first described in the US. Viruses can be difficult to score visually, compromising seed certification programs. The focus of this proposal is: i) the collection of Potato Virus Y (PVY) field isolates representative of those compromising potato production, and ii) testing commercial varieties and breeding lines to assess their resistance phenotypes.
