Abstract

NemaRus, a russet-skinned potato variety resistant to race A of the golden nematode (Globodera rostochiensis), is medium-late in maturity (110 days) and adapted primarily to the Northeastern United States and Northern Florida. Tubers are oblong to long with moderately shallow eyes, and medium-to-heavy russeted skin. The specific gravity of NemaRus is similar to the popular Western U.S.A. fresh market russet variety Centennial Russet. Flesh is creamy white. Glycoalkaloid content of NemaRus averages about 12.0 mg/100 g fresh tissue. NemaRus is field-immune to the common strains of potato virus X and to tuber net necrosis caused by late current-season infection by the potato leaf roll virus. It is resistant to race O ofPhytophthora infestans to tuber rot caused byFusarium sambucinum & F. coeruleum; tolerant to scab, Verticillium wilt, and the pinkeye bacterial disease complex. It is also highly resistant to internal tuber net necrosis associated with high temperatures during tuber initiation and enlargement. NemaRus yielded 24% more U.S. No. 1 tubers than BelRus in Maine and 22% more than Centennial Russet in Northern Florida.

Compendio

NemaRus, una variedad de papa de piel rojiza resistente a la raza A del nematodo dorado (Globodera rostochiensis), es semi-tardía en maduración (110 días) y principalmente adaptada al noreste de los Estados Unidos y al norte de Florida. Los tubérculos son oblongos a alargados con ojos moderadamente superficiales y con una piel mediana a fuertemente rojiza. La gravedad específica de NemaRus es similar a la de la popular variedad rojiza para consumo fresco del oeste norteamericano, Centennial Russet. La pulpa es blanco-cremosa. El contenido de glico-alcaloides de NemaRus promedia aproximadamente 12,0 mg/100 g de tejido fresco. NemaRus posee inmunidad de campo a las razas comunes del virus X de la papa y a la necrosis en red del tubérculo causada por la infección con el virus del enrollamiento de la hoja al final de la temporada. Es resistente a la raza O dePhytophthora infestans y a la pudricíon del tubérculo causada porFusarium sambucinum + F. coerculeum; tolerante a la sarna común, a la marchitez porVerticillium y al complejo de la enfermedad bacteriana ojo rosado. Es también muy resistente a la necrosis en red del interior de los tubérculos asociada con las altas temperaturas durante el inicio de la tuberización y crecimiento de los tubérculos. NemaRus rindió 24% más de tubérculos U.S. No. 1 que BelRus en Maine y 22% más que Centennial Russet en el norte de Florida.
