The USDA Temperate Tree Fruit and Vegetable Research Unit has three scientists working on potato germplasm improvement at the Prosser worksite, co-located with the Washington State University IAREC. This research team aims to develop improved germplasm for use by other breeding programs and to develop new breeding lines with improved disease and pest resistance, nutritional value and quality traits. The group has over 3000 sq ft of laboratory space, 5000 sq ft of greenhouse space and access to over 1000 acres of IAREC research farms.
