Palisade Russet: A Late Blight Resistant Potato Cultivar Having a Low Incidence of Sugar Ends and High Specific Gravity


Palisade Russet is a medium-late maturing, lightly russeted potato cultivar notable for its resistance to late blight (Phytophthora infestans) infection of foliage and tuber. Palisade Russet is suitable for processing with low tuber glucose concentrations observed following long-term storage at a temperature as low as 5.6°C with consistently acceptable fry color scores (USDA value ≤2.0) following storage at temperatures of 5.6 to 8.9°C. Reducing sugars are also maintained uniformly throughout the tuber, resulting in a low incidence of sugar ends in French fries relative to standard processing cultivars such as Russet Burbank and Ranger Russet. Palisade Russet has shown high specific gravities in western production regions of the U.S. which may limit its acceptance by the western processing industry. However, in potato production regions with inherently low specific gravities, Palisade Russet could have potential as a processing cultivar. In full-season trials conducted in Idaho, Oregon, and Washington over a 5 year period, the average total yield of Palisade Russet across all three states was very similar to yields observed for Ranger Russet and Russet Burbank. However, the U.S. No. 1 yield of Palisade Russet was 3% and 31% higher relative to Ranger Russet and Russet Burbank, respectively. In addition to late blight, Palisade Russet is also resistant to Verticillium wilt, black dot, and pink rot, and has a moderate level of resistance to net necrosis, PVY, and early blight of both the foliage and tuber. The disease resistances of Palisade Russet make it a good candidate for organic production, or for use by growers seeking reduced pesticide inputs. Palisade Russet displays a low incidence of second growth and growth cracks, especially relative to Russet Burbank, and is intermediate between Ranger Russet and Russet Burbank for incidence of hollow heart/brown center. Blackspot bruise expression for Palisade Russet is less pronounced than for either Ranger Russet or Russet Burbank, however it is slightly more susceptible to shatter bruise. Palisade Russet was released in 2011 by the USDA-ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington, and is a product of the Pacific Northwest Potato Variety (Tri-State) Development Program.


Palisade Russet es una variedad de madurez mediana a tardía, ligeramente tipo russet, notable por su resistencia a la infección del follaje y del tubérculo al tizón tardío (Phytophthora infestans). Palisade Russet es deseable para proceso con concentraciones bajas de glucosa en el tubérculo, observado después de almacenamiento a largo plazo a temperatura tan baja como 5.6°C con consistentemente aceptables calificaciones de color de freído (valor USDA ≤ 2.0) después de almacenamiento a temperaturas de 5.6 a 8.9°C. También se mantienen uniformemente los azucares reductores por todo el tubérculo, resultando en baja incidencia de azúcar en los extremos en papas a la francesa en relación con las variedades estándar de proceso, tales como Russet Burbank y Ranger Russet. Palisade Russet ha mostrado altas gravedades específicas en las regiones de producción del oeste de los E.U., lo cual puede limitar su aceptación por la industria de procesado del oeste. No obstante, en regiones de producción de papa con inherentes bajas gravedades específicas, Palisade Russet pudiera tener potencial como variedad de procesamiento. En ensayos de temporada completa en Idaho, Oregon y Washington en un período de cinco años, el promedio total de rendimiento de Palisade Russet a lo largo de los tres Estados fue muy similar a los observados para Ranger Russet y Russet Burbank. No obstante, el rendimiento de U.S. 1 de Palisade Russet fue 3% y 31% más alto en relación a Ranger Russet y Russet Burbank, respectivamente. Además del tizón tardío, Palisade Russet también es resistente a marchitez por Verticillium, mancha negra y pudrición rosa, y tiene un nivel de resistencia moderado a la necrosis, PVY y a tizón temprano, tanto en follaje como en tubérculo. Las resistencias a las enfermedades de Palisade Russet la hacen un buen candidato para producción orgánica, o para uso por productores que buscan la reducción de insumos por paguicidas. Palisade Russet muestra baja incidencia de crecimiento secundario y de cuarteaduras, especialmente en relación a Russet Burbank, y es intermedia entre Ranger Russet y Russet Burbank en incidencia de corazón hueco o centro café. La expresión de la mancha negra por daño mecánico para Palisade Russet es menos pronunciada que para cualquiera de Ranger Russet o Russet Burbank, no obstante, es ligeramente más susceptible a rompimientos por raspaduras. Palisade Russet se liberó en 2011 por USDA-ARS y las Estaciones Experimentales Agrícolas de Idaho, Oregon y Washington, y es un producto del Programa de Desarrollo de Variedades de Papa del Pacífico Noroeste (Tri-State).
