Interpretive Summary:

Technical Abstract: The Tri-State Potato Variety Development Program released two potato cultivars in 2011: Palisade Russet and Teton Russet. Palisade Russet (PR) is notable for having resistance to foliar and tuber late blight. PR is also resistant to Verticillium wilt, black dot, and pink rot, and has a moderate resistance to net necrosis, potato virus Y, and early blight of both the foliage and tuber. The disease resistances of PR make it a good candidate for organic production. PR has shown high specific gravities in western US production regions which may limit its acceptance by the western processing industry. However, in potato production regions with inherently low specific gravities, PR would have potential as a processing cultivar, with percentages of fry sugar ends not exceeding 8% in multiple trial sites over years of evaluation--substantially lower percentages than processing cultivars currently being utilized by industry. Teton Russet (TR) is a dual-purpose variety with early bulking potential and a high yield of attractive tubers. TR is notable for its resistances to dry rot caused by F. sambucinum and to common scab, and has higher protein and vitamin C content than those of most standard varieties. TR has potential for the early fresh market, and could be a possible replacement for Russet Norkotah. Evaluations of processing quality indicate that TR can also produce premium quality fries, with lower concentrations of asparagine contributing to reduced acrylamide formation.
