Abstract

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.

Resumen

Yukon Nugget es una papa de especialidad de ciclo intermedio, con pulpa amarilla y ojos rojos evidentes. Esta variedad se desarrolló para suministrar a la industria de la papa una alternativa a Yukon Gold. El perfil general del tamaño del tubérculo de Yukon Nugget es más pequeño y uniforme que Yukon Gold, y típicamente produce un promedio de cuatro tubérculos más por planta que Yukon Gold. Los tubérculos de Yukon Nugget son ideales para hervir, cocinar, para el horno de microondas, y tiene cualidades culinarias y nutricionales generalmente similares a las de Yukon Gold. Yukon Nugget tiene resistencia extrema al Virus X de la papa debido a la presencia del alelo Rx1 de resistencia al PVX. También tiene resistencia moderada a la roña polvorienta y al tizón tardío en el tubérculo. Yukon Nugget tiene menos decoloración vascular y en el extremo del tallo, y menos corazón hueco que Yukon Gold. Yukon Nugget es similar a Yukon Gold en términos de susceptibilidad a varias enfermedades importantes de la papa, tales como el PVY, PLRV y al tizón tardío del follaje. Se liberó en el 2013 por las Estaciones Agrícolas Experimentales de Oregon, Idaho y Washington y el USDA-ARS, y es un producto del Programa de desarrollo de Variedades Triestatal del Pacifico Nor-Occidental.
