  • © 2016, The Potato Association of America. Yukon Nugget is a mid-season specialty potato with yellow flesh, yellow skin and distinct red eyes. Yukon Nugget was developed to provide the potato industry with an alternative to Yukon Gold. The overall tuber size profile of Yukon Nugget is smaller and more uniform than Yukon Gold and it typically produces an average of four more tubers per plant than Yukon Gold. Yukon Nugget tubers are ideal for boiling, baking, and microwaving, and have culinary and nutritional qualities generally similar to Yukon Gold. Yukon Nugget has extreme resistance to Potato Virus X due to presence of PVX resistance allele Rx1. It also has moderate resistance to powdery scab and tuber late blight. Yukon Nugget has less vascular and stem end discoloration and less hollow heart than Yukon Gold. Yukon Nugget is similar to Yukon Gold in terms of susceptibility to several major potato diseases, such as PVY, PLRV, and foliage late blight. It was released in 2013 by the Agricultural Experiment Stations of Oregon, Idaho and Washington and the USDA-ARS, and is a product of the Pacific Northwest (Tri-State) Potato Variety Development Program.
