Yukon Nugget: a mid-season yellow skin, yellow flesh specialty potato with extreme resistance to potato virus X. American Journal of Potato Research. 93(6):602-608. Interpretive Summary: Potato cultivars currently available in commercial markets have many positive attributes, but typically have at least some limitations that if improved upon would benefit consumers and the industry. Yukon Nugget is a new mid-season specialty potato with yellow flesh that is a product of the Pacific Northwest Potato Variety (Tri-State) Development Program and developed by scientists at the USDA-ARS, Oregon State University, Washington State University and the University of Idaho to provide the potato industry an alternative to Yukon Gold. Yukon Nugget is smaller and more uniform than Yukon Gold and typically produces more tubers per plant than Yukon Gold. Yukon Nugget tubers are ideal for boiling, baking and microwaving and have exceptional taste and nutritional qualities. Yukon Nugget has extreme resistance to Potato Virus X, moderate resistance to powdery scab and tuber late blight and less discoloration and hollow heart than Yukon Gold. Collectively, Yukon Nugget has traits that appeal to consumers, protect grower profitability and decrease yield losses due to disease and quality issues. Technical Abstract: Yukon Nugget is a mid-season specialty potato with yellow flesh, yellow skin and distinct red eyes. Yukon Nugget was developed to provide potato industry an alternative to Yukon Gold. The overall tuber size profile of Yukon Nugget is smaller and more uniform than Yukon Gold and typically produces 4-5 more tubers per plant ithan Yukon Gold. Yukon Nugget tubers are ideal for boiling, baking and microwaving with exceptional taste and nutritional qualities. Yukon Nugget has extreme resistance to Potato Virus X based on the presence of PVX resistance allele Rx1 and has moderate resistance to powdery scab and tuber late blight. It has less vascular and stem end discoloration and less hollow heart than Yukon Gold. Yukon Nugget is susceptible to major potato diseases such as PVY, PLRV and foliage late blight as is Yukon Gold. 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 Potato Variety (Tri-State) Development Program. |
