Interpretive Summary: Century Russet is a new russet skinned potato variety that has been released by the Tri-State Potato Variety Development Program in the Pacific Northwest and cooperating programs in Texas, Colorado, and California. The cross was made at Aberdeen, ID by USDA-ARS. The initial selection was made in Idaho, subsequent testing and the more advanced development work were done in Oregon. Large-scale seed production and evaluation for fresh market use were done in Oregon, Colorado, California, and Texas. Century Russet is suited for fresh market producing higher yields of well-shaped tubers than the standard varieties Russet Norkotah and Russet Burbank. It is not suitable for frozen French fry production because of lower solids content and darker fry color.
Technical Abstract: Century Russet, a high-yielding, late-maturing variety suitable for fresh tablestock use, was jointly released in 1995 by Agricultural Experiment Stations in Oregon, Idaho, Washington, Colorado, California and Texas and the USDA Agricultural Research Service. Extremely high yields have been observed for Century Russet in variety trials conducted in Oregon and throughout the western United States under a wide range of soil and climatic conditions. Century Russet produced 40 percent higher marketable yields than Russet Burbank and 67 percent higher marketable yields than Russet Norkotah in 11 regional trials conducted over a three-year period in seven western states. Uniform tuber shape, high yields of count carton sizes, and attractive tuber appearance make Century Russet well suited for the fresh market industry. It is not recommended for chipping or processing into frozen products because of low solids and dark fry color. Century Russet is highly resistant to Verticillium wilt and consistently develops less hollow heart, brown center, and other internal defects than Russet Burbank. It requires more time between vine kill and harvest than Russet Burbank for adequate tuber maturity and skin set. Bruised Century Russet tubers are susceptible to early blight and Fusarium infection.
