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 of Phytophthora infestans to tuber rot caused by Fusarium 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.
