ORIGIN: Century Russet was selected in Oregon from an Aberdeen (USDA) cross of A6789-7 x A6680-5. It was tested as A74212-1E and was released in 1995 by the Agricultural Experiment Stations of California, Colorado, Oregon, Idaho, Texas and Washington and the USDA.

CHARACTERISTICS: Century Russet has a late maturing vine although the tubers reach acceptable size early- to mid-season. It produces an exceptionally high yield of long, lightly russetted tubers. It is well suited for the fresh market.

Plants are large with a decumbent growth habit. Stems are unpigmented with inconspicuous wings and slightly swollen nodes. Leaves are medium sized, dark green with a bluish cast and have abundant pubescence. Flowers are abundant early in the season. Buds are green, corollas medium-sized and white, anthers large and yellow.

Tubers are long and cylindrical to slightly flattened. Skin is lightly and uniformly russeted. Eyes medium-shallow with a distinct eyebrow, moderate in number and evenly distributed. Dormancy is medium.

STRENGTHS & WEAKNESSES: Century Russet produces an exceptionally high yield in comparison to other russet type varieties. Tuber specific gravity is slightly lower than Russet Burbank. Tubers are resistant to most external and internal defects including second growth, growth cracks, stress malformations and hollow heart. It is immune to PVX and resistant to Verticillium wilt, common scab and foliar early blight. Century Russet is susceptible to leafroll-induced net necrosis. Tuber sugar content is too high for Century Russet to be utilized by the frozen processing industry, however, it is well suited for tablestock.
