Abstract
Lemhi Russet, a new oblong, russet-skinned potato variety, was released by the U.S. Department of Agriculture and the Agricultural Experiment Stations of Idaho, Oregon, California, Washington, and North Dakota on September 23, 1980. The tubers of Lemhi Russet have been blockier, larger, 6% higher in solids, 50% lower in reducing sugars, and 25% higher in vitamin C than those of Russet Burbank. Lemhi Russet has averaged 34% more U.S. No. 1 tubers than Russet Burbank in 6 years of trials in five states. It was superior to Norgold Russet in yield and specific gravity in early harvest trials. In pilot plant and laboratory trials, Lemhi Russet made excellent french fries, baked well with a mealy texture, but sloughed when boiled. Lemhi Russet has a high degree of resistance to scab and net necrosis, but is susceptible to potato viruses S, X, Y, and to the leafroll virus. It is also susceptible to bruising and blackspot.
Resumen
Una nueva variedad, Lemhi Russet, de forma oblonga y piel tipo russet, ha sido liberada por el Departamento de Agricultura de los Estados Unidos y por las Estaciones Experimentales de Idaho, Oregon, California, Washington, y Dakota del Norte en septiembre 23 de 1980. Los tubérculos de esta nueva variedad son más grandes, 6% más alto en sólidos, 50% más bajo en azúcares reductores y 22% más alto en vitamina C que Russet Burbank. Esta variedad ha promediado 34% más de tubérculos de primera bajo los standards de Estados Unidos que Russet Burbank durante seis años de ensayos en cinco estaciones. Fue superior a Norgold Russet en rendimiento y gravedad específica en ensayos tempranos. En pruebas de laboratorio y planta piloto, Lemhi Russet demostró excelencia para papas fritas, horneado y textura harinosa, pero se deshace al hervido. Tiene gran resistencia a la sarna y necrosis en red, pero es susceptible a los virus S, X, Y y al enrrollamiento de la hoja. También es susceptible a daños mecánicos y mancha negra.
