ORIGIN: Selected from a cross made in North Dakota between ND9526-4 Russ x ND9687-5 Russ and tested as ND534-4 Russ. Released by North Dakota in 1987.

CHARACTERISTICS: Russet Norkotah is an early to medium maturity cultivar grown primarily for the fresh market. Yields are medium and tuber specific gravity is low to medium. Plants are medium sized, slightly upright; stems are medium thick with non-pigmented nodes and internodes. Leaves are medium in size, open and slightly pubescent. Buds are slightly pigmented, corolla is white and anthers are yellow-orange. Tubers are long to oblong, smooth, russeted and have shallow, bright golden eyes. Tuber flesh is white, dormancy is medium and sprouts are white with some purple pigment at the tip.

STRENGTHS & WEAKNESSES: Russet Norkotah has a very attractive general appearance with a high percentage of U.S. No. 1 tubers. Tuber shape and type are very desirable for the count-carton market. The variety is not well suited for processing. It is adaptable to many of the growing areas.

Russet Norkotah is susceptible to most viruses and late blight. It is very susceptible to Verticillium wilt and early blight. It is reported to have some tolerance to common scab and silver scurf.
