Interpretive Summary: Sage Russet is a potato variety released in 2009 from the Northwest Potato Variety (Tri-State) Development Program. This variety is notable for having high yields with a very high percentage of marketable tubers in both early and full-season trials. Sage Russet also has good tuber appearance, excellent processing quality with resistance to cold-sweetening in storage, and high concentrations of both protein and Vitamin C in its tubers. It received very high merit ratings for both processing and fresh market usage in Western Regional trials from 2005-2007, and can be considered a dual-purpose variety.

Technical Abstract: Sage Russet was released in 2009 by Oregon State University, in cooperation with the USDA-ARS and the Agricultural Experiment Stations of Idaho and Washington. It is a product of the Northwest Potato Variety (Tri-State) Development Program. Sage Russet has a medium-early maturity and produces long, somewhat flattened tubers with medium russeting of the skin. Total yields of Sage Russet are similar to those of Russet Burbank, and Ranger Russet but are significantly higher than those of Russet Norkotah. Sage Russet has significantly higher U.S. No.1 yields than Russet Burbank, Russet Norkotah and Ranger Russet. It can be grown as an early or late crop with high yields and minimal internal defects. It achieved very high scores in processing and fresh market trials from 2005 through 2007 in Western Regional trials and can be considered for both processing and fresh markets. Sage Russet has medium to high fertility requirement with high nitrate use efficiency and medium storage capability. Chemical analyses have shown Sage Russet to have higher protein and vitamin C content than standard varieties. Sage Russet has moderate specific gravity, and produces lighter fry color than the industry standard controls. The color of fried strips following tuber storage at 4.4°C and 7.2°C is significantly lighter for Sage Russet than the control varieties. Relative strengths include high yield with a very high proportion of U.S. No. 1 tubers, good tuber appearance, excellent processing quality, and resistance to cold sweetening. Sage Russet has been found to be susceptible to Fusarium wilt and is prone to shatter bruise. Sage Russet is moderately resistant to early die, early blight, common scab, and is resistant to tuber late blight.
