Defender: A High-Yielding, Processing Potato Cultivar with Foliar and Tuber Resistance to Late Blight

The potato cultivar Defender is high-yielding, white-skinned, and notable for having foliar and tuber resistance to late blight infection caused byPhytophthora infestans (Mont.) de Bary. It was released in 2004 by the USDA-ARS and the agricultural experiment stations of Idaho, Oregon, and Washington. Defender is suitable for processing into french fries and other frozen potato products directly from the field or from storage. Defender also may be used for fresh markets in regions such as California, where cultivars with long tubers and white skin are traditionally grown. Resistances to late blight and other potato diseases make Defender an ideal candidate for organic potato production. Defender consistently produced greater total and U.S. No. 1 yields than ‘Russet Burbank’ in Idaho trials. In early harvest trials conducted in the western U.S., average total yields of Defender were 17% and 23% greater than yields for ‘Ranger Russet’ and ‘Shepody’, respectively. In full-season trials conducted in the western U.S., Defender averaged 10% and 15% higher yields than Ranger Russet and Russet Burbank, respectively. Specific gravity of Defender is consistently high, with values comparable to those of Ranger Russet; tuber ascorbic acid (Vitamin C) levels are also high. In addition to late blight, Defender also is resistant to tuber early blight (Alternaria solani, (Ellis & G. Martin), L.R. Jones & Grout), potato virus X, and net necrosis; it has moderate levels of resistance to Verticillium wilt (Verticillium dahliae, Kleb), pink rot, foliar early blight, corky ringspot, and Erwinia soft rot. Defender is susceptible to scab (common and powdery) and potato leafroll virus; it has moderate susceptibility to dry rot (Fusarium spp.) and potato virus Y. Susceptibilities to internal necrosis, tuber greening, and blackspot bruise also have been noted, but may be minimized through cultural and harvest practices.ResumenDefender es un cultivar de papa de alto rendimiento, piel blanca y excelente por su resistencia al tizón tardío causado porPhytophthora infestans (Mont.) de Bary, tanto a la infección foliar como a la de los tubérculos. Ha sido liberada el 2004 por USDA-ARS y las Estaciones Experimentales Agrícolas de Idaho, Oregon y Washington. Defender es apropiado para el procesamiento de papa frita y otros productos congelados de papa, directamente del campo o del almacén. Defender puede también ser usado en regiones como California, donde se cultivan tradicionalmente variedades de tubérculos alargados y piel blanca. La resistencia al tizón tardío y otras enfermedades de la papa hace de Defender un candidato ideal para la producción orgánica. Defender tuvo consistentemente un mayor rendimiento de tubérculos de grado “US No. 1” que Russet Burbank en pruebas en Idaho. En ensayos de cosecha temprana realizados en el oeste de EUA, el promedio de rendimiento total de Defender fue de 17 y 23% mayor que el de las variedades Ranger Russet y Shepody respectivamente. En ensayos de ciclo completo realizadas en el oeste, Defender tuvo rendimientos 10 y 15% mayores que Ranger Russet y Russet Burbank respectivamente. El peso específico de Defender es consistentemente alto, con valores comparables a los de Ranger Russet y los niveles de ácido ascórbico (Vitamina C) son también altos. Además de ser resistente al tizón tardío, Defender es también resistente al tizón temprano (Alternaria solani (Ellis & G. Martín) L. R. Jones & Grout), Virus X de la papa y necrosis en red. Tiene niveles moderados de resistencia a marchitez por Verticillium (Verticillium dahliae Kleb.), pudrición rosada, tizón foliar temprano, mancha corchosa en anillo y pudrición blanda causada por Erwinia. Defender es susceptible a la sarna (común y polvorienta) y al virus del enrollamiento; tiene moderada susceptibilidad a la pudrición seca (Fusarium spp.) y al virus Y de la papa. También se ha notado susceptibilidad a necrosis interna, verdeamiento del tubérculo y mancha negra, pero estas pueden minimizarse a través de prácticas culturales.

Umatilla Russet: A full season long Russet for processing and fresh market use

Umatilla Russet, a moderately late maturing variety especially suitable for frozen French fry processing but also acceptable for tablestock use (boiling, and baking), was jointly released by the Agricultural Experiment Stations of Oregon, Idaho, and Washington and the U.S. Department of Agriculture in 1998. Umatilla Russet was evaluated in irrigated trials in Oregon from 1988 to 1997, and in western regional trials from 1989 to 1991. Total yields were similar to those of Russet Burbank, but Umatilla Russet produced higher marketable yields. In three years of regional trials at up to 13 locations in seven western states, Umatilla Russet averaged 40.5 Mg/ha compared with 32.4 Mg/ha for Russet. Burbank. Umatilla Russet fry color and specific gravity are consistently equal to or better than for Russet Burbank. Umatilla Russet is less susceptible toVerticillium wilt than Russet Norkotah, less susceptible to net necrosis than Russet Burbank, and resistant to PVX. It is susceptible to PLRV and expresses foliar symptoms of PVY more clearly than Russet Norkotah. Umatilla Russet is less susceptible to tuber infection and decay caused byPhytophthora infestans than Ranger Russet and Russet Norkotah. Umatilla Russet is less susceptible to hollow heart, brown center, growth cracks, and sugar ends, but more susceptible to blackspot and shatter bruise than Russet Burbank

Alturas: A Multi-Purpose, Russet Potato Cultivar with High Yield and Tuber Specific Gravity

Abstract‘Alturas’, a late-maturing, high-yielding, russet potato cultivar with high tuber specific gravity, was released in 2002 by the USDA-ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington. Originally selected for dehydration processing, its cold-sweetening resistance also makes it suitable for processing out of storage into french fries and other frozen potato products. Culinary quality is high, with larger tubers suitable for fresh market if heavily russeted skin is not essential. Alturas consistently produced greater total and U.S. No. 1 yields than ‘Russet Burbank’ and ‘Ranger Russet’ in southern Idaho trials. Across other western trial sites, total yields of Alturas have on average been 29% and 14% greater than Russet Burbank and Ranger Russet, respectively. Alturas is resistant to Verticillium wilt (Verticillium dahliae) and early blight (Alternaria solani). Compared with Russet Burbank and Ranger Russet, Alturas is less susceptible to corky ringspot and foliar and tuber infection by late blight (Phytophthora infestans). It also is less susceptible to tuber net necrosis and Fusarium dry rot than Russet Burbank, and is more resistant to common scab (Streptomyces scabies) than Ranger Russet. However, Alturas is more susceptible to infection by PVY and PVX than Ranger Russet. Total nitrogen application recommendations for Alturas are approximately 40% less than those for Russet Burbank. Alturas requires 15% to 20% more water during the growing season than does Russet Bur-bank.

Bannock Russet: A Dual-Purpose, Russet Potato Cultivar With High U. S. No. 1 Yield and Multiple Disease Resistances

Bannock Russet, a late-maturing, long russet potato cultivar, was released in 1999 by the USDA-ARS and the experiment stations of Idaho, Oregon, and Washington. It is suitable for processing into french fries and other frozen products. Its attractive russeted skin and excellent culinary qualities also make it suitable for fresh market. Bannock Russet, in comparisons with Russet Burbank, has consistently produced greater U.S. No. 1 yields in trials conducted throughout southern Idaho. In other western trial sites, total yields of Bannock Russet have been comparable to or smaller than that of Russet Burbank, but its percentage of undersize and cull potatoes is consistently less. Bannock Russet is resistant to potato virus Y (PVY), Verticillium wilt, common scab, and leafroll net necrosis. It also has moderate resistance to early blight (foliar and tuber) andErwinia soft rot. With respect to other potato diseases/disorders, Bannock Russet’s level of susceptibility is similar to that of Russet Burbank; the exception being shatter bruise, with Bannock Russet displaying a greater susceptibility. Cultural management guidelines have been developed to minimize shatter bruise in Bannock Russet. Bannock Russet’s multiple disease resistances coupled with its low nitrogen requirement, make it a low-input cultivar that could significantly reduce growers’ production costs.ResumenBannock Russet, un cultivar de papa de maduración tardía, alargado y rojizo, fue liberado en 1999 por USDA-ARS y las estaciones experimentales de Idaho, Oregón y Washington. Es adecuado para el procesamiento de papas fritas a la francesa y otros productos congelados. Su atractiva piel rojiza y sus excelentes cualidades culinarias lo hacen igualmente adecuado para el mercado fresco. En los ensayos realizados en todo el sur de Idaho, en comparación con Russet Burbank, la variedad Bannock Russet sistemáticamente ha obtenido el primer lugar en rendimiento de los Estados Unidos. En otros campos de prueba del oeste, los rendimientos totales de Bannock Russet han sido equivalentes o más bajos que los de Russet Burbank, pero el porcentaje de papas con tamaño insuficiente y de desecho es notablemente menor. Bannock Russet es resistente al virus Y de la papa (PVY), a la verticilosis, sarna común y a la necrosis reticulada de enrollamiento de la papa. También posee resistencia moderada al tizón temprano (foliar y tubérculo) y a la pudrición blanda por Erwinia. Respecto a otras enfermedades o transtornos de la papa, el nivel de susceptibilidad es similar al de Russet Burbank, con excepción de que Bannock Russet es más proclive a que se produzcan magulladuras con rotura de la piel del tubérculo. Las pautas de manejo cultural han sido desarrolladas para reducir al mínimo dichas magulladuras en Bannock Russet. La múltiple resistencia a enfermedades de este cultivar se aúna a su bajo requerimiento de nitrógeno, que convierte a Bannock Russet en un cultivar de baja inversión que puede reducir significativamente los costos de productión de los agricultores.

Clearwater Russet: A Dual-Purpose Potato Cultivar with Cold Sweetening Resistance, High Protein Content, and Low Incidence of External Defects and Sugar Ends

Clearwater Russet is a medium-late maturing, russet-skinned, potato cultivar suitable for processing or fresh pack. It is notable for having a low incidence of external defects that contributes to its high U.S. No 1 yield relative to the dual-purpose industry standard, Russet Burbank. Clearwater Russet also maintains low glucose concentrations in its tubers during long-term storage making it an exceptional processing variety. With its low incidence of sugar ends and cold-induced sweetening resistance, Clearwater Russet can be stored at a temperature of 7.2°C for up to 250xa0days without the need for reconditioning; fry color from this storage regime is consistently ≤1.0 (USDA Fry Color Scale). This cultivar is also notable for its high tuber protein content, which was 33% greater than that of Russet Burbank. In full-season trials conducted over a 3-year period in California, Colorado, Idaho, Oregon, and Washington, Clearwater Russet had total yields slightly lower than Ranger Russet and Russet Burbank, but averaged 1% and 33% higher U.S. No. 1 yields, respectively, across all states. Average specific gravity of Clearwater Russet is comparable to Ranger Russet and significantly higher than Russet Burbank. Clearwater Russet is resistant to potato virus X (PVX) and tuber late blight and is moderately resistant to Verticillium wilt, common scab, and the common strain of potato virus Y (PVYO). Symptoms of infection with two necrotic strains of PVY were not observed in tubers of Clearwater Russet or Russet Burbank, but were observed in Ranger Russet. Blackspot bruise reaction for Clearwater Russet is less pronounced than for either Ranger Russet or Russet Burbank. The incidence of hollow heart in Clearwater Russet is intermediate between Ranger Russet and Russet Burbank. Internal brown spot has been noted as a problem for Clearwater Russet in the Columbia Basin of Oregon, but has not been observed as problematic in other growing regions. Clearwater Russet was released in 2008 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.ResumenClearwater Russet es una variedad de madurez de intermedia a tardía, de piel corchosa, tanto para proceso como para consumo en fresco. Es notable por tener una baja incidencia de defectos externos que contribuye a su alto rendimiento de US No. 1, en relación con el estándar de Russet Burbank de la industria para doble propósito. Clearwater Russet también mantiene bajas concentraciones de glucosa en sus tubérculos durante almacenamiento por largos períodos haciéndola una variedad excepcional para procesamiento. Con su baja incidencia de azúcares finales y su resistencia al endulzamiento inducido por frío, Clearwater Russet puede almacenarse a temperaturas de 7.2°C por hasta 250 días sin necesidad de reacondicionamiento; el color de freído con este régimen de almacenamiento es consistentemente ≤1.0 (Escala de Color de Freído USDA). Esta variedad también es notable por su alto contenido proteico del tubérculo, que fue 33% mayor que el de Russet Burbank. En ensayos de toda la temporada que se desarrollaron en un período de tres años en California, Colorado, Idaho, Oregon, y Washington, Clearwater Russet tuvo rendimientos totales ligeramente abajo que Ranger Russet y Russet Burbank, pero promedió 1% y 33% más altos rendimientos de US No. 1, respectivamente, en todos los estados. El promedio de la gravedad específica de Clearwater Russet es comparable al de Ranger Russet y significativamente mayor que el de Russet Burbank. Clearwater Russet es resistente al virus X de la papa (PVX) y al tizón tardío de tubérculo, y es moderadamente resistente al marchitamiento por Verticillium, a la roña común, y a la variante común de virus Y de la papa (PVY0). No se observaron síntomas de infección con dos variantes necróticas de PVY en tubérculos de Clearwater Russet o Russet Burbank, pero sí se vieron en Ranger Russet. La reacción de manchas oscuras por golpes para Clearwater Russet es menos pronunciada que para Ranger Russet o Russet Burbank. La incidencia de corazón hueco en Clearwater Russet es intermedia entre Ranger Russet y Russet Burbank. Se ha notado que la mancha café interna es un problema para Clearwater Russet en la rivera del Columbia de Oregon, pero no se ha visto como problemático en otras regiones de cultivo. Se liberó Clearwater Russet en 2008 por el USDA-ARS y por las estaciones experimentales de Idaho, Oregon, y Washington, y es un producto del Programa de Desarrollo de Variedades de Papa del Noroeste del Pacífico (Tri-State o tres estados).

Alpine Russet: A Potato Cultivar Having Long Tuber Dormancy Making it Suitable for Processing from Long-term Storage

Alpine Russet is a later maturing, oblong-long, lightly russeted potato cultivar, notable for having tuber dormancy comparable to Russet Burbank. Processing quality of Alpine Russet from long-term storage is superior to Russet Burbank, with low percent reducing sugars and uniform fry color due to a low percentage difference of sugars between the bud and stem ends. Alpine Russet yields were comparable to Russet Burbank in early harvest trials and were comparable or significantly larger in late harvest trials depending on the location. At two late season locations, Alpine Russet had the largest total and percent No. 1 yields and the largest percent mid-range No. 1 tubers compared to Ranger Russet and Russet Burbank. It has moderately high specific gravity and is resistant to most external and internal defects. Alpine Russet has been evaluated in public and industry trials throughout the Western U.S. for over 15xa0years.ResumenAlpine Russet es una variedad de papa de madures tardía, larga-oblonga, ligeramente como Russet, notable por tener una dormancia del tubérculo comparable a Russet Burbank. La calidad de procesamiento de Alpine Russet después de un almacenamiento prolongado es superior a Russet Burbank, con bajo porcentaje de azúcares reductores y color uniforme de freído debido a la baja diferencia en porcentaje de azúcares entre la yema apical y la base. Los rendimientos de Alpine Russet fueron comparables a Russet Burbank en ensayos de cosecha temprana y fueron comparables o significativamente mayores en ensayos de cosecha tardía, dependiendo del lugar. En dos lugares de ciclo tardío, Alpine Russet tuvo los mayores rendimientos totales y en porcentaje de No. 1, y el mayor porcentaje de tubérculos de amplitud media No. 1 comparada con Ranger Russet y Russet Burbank.
