Interpretive Summary: Alturas, a late- maturing, high-yielding, russet potato cultivar with high tuber specific gravity, was released in 2002 by the USDA-ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington. Originally selected for dehydration processing, its resistance to the accumulation of sugars during long-term storage also makes it suitable for processing out of storage into French fries and other frozen potato products. In replicated yield trials at western trial sites, total yields of Alturas have on average been 29% and 14% greater than the standard cultivars Russet Burbank and Ranger Russet, respectively. Alturas is resistant to Verticillium wilt and early blight--diseases responsible for the symptoms of early dying in potato. Compared with Russet Burbank and Ranger Russet, Alturas is less susceptible to corky ringspot and foliar and tuber infection by late blight (Phytophthora infestans). It also is less susceptible to tuber net necrosis and Fusarium dry rot than Russet Burbank, and is more resistant to common scab (Streptomyces scabies) than Ranger Russet. However, Alturas is more susceptible to infection by PVY and PVX than Ranger Russet. Alturas requires 40% less nitrogen than Russet Burbank, but requires 15-20 % more water during the growing season. Patent Info: Retention of intellectual property rights: PVP will be applied for by the University of Idaho on behalf of the USDA-ARS; the USDA-ARS will be co-owner as well as the University of Idaho, Oregon State University, and Washington State University.

Technical Abstract: Alturas, a late- maturing, high-yielding, russet potato cultivar with high tuber specific gravity, was released in 2002 by the USDA-ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington. Originally selected for dehydration processing, its cold-sweetening resistance also makes it suitable for processing out of storage into French fries and other frozen potato products. Culinary quality is high, with larger tubers suitable for fresh market if heavily russeted skin is not essential. Alturas consistently produced greater total and U.S. No. 1 yields than Russet Burbank and Ranger Russet in southern Idaho trials. Across other western trial sites, total yields of Alturas have on average been 29% and 14% greater than Russet Burbank and Ranger Russet, respectively. Alturas is resistant to Verticillium wilt and early blight (Alternaria solani). Compared with Russet Burbank and Ranger Russet, Alturas is less susceptible to corky ringspot and foliar and tuber infection by late blight (Phytophthora infestans). It also is less susceptible to tuber net necrosis and Fusarium dry rot than Russet Burbank, and is more resistant to common scab (Streptomyces scabies) than Ranger Russet. However, Alturas is more susceptible to infection by PVY and PVX than Ranger Russet. Alturas requires 40% less nitrogen than Russet Burbank, but requires 15-20 % more water during the growing season.
