Interpretive Summary: New, high-quality potato cultivars that increase sustainability and yields can help ensure food security, provide more options for consumers and protect grower profitability. Scientists with the USDA-ARS, Oregon State University, University of Idaho and Washington State University developed a new potato variety, Echo Russet, released by the Tri-State Breeding Program. Echo Russet has greater overall yields than Russet Norkotah and a higher yield of US No. 1 potatoes than standard varieties. Echo Russet has high merit scores for fresh and processing qualities. It has good quality traits, including a light fry color, low acrylamide, high specific gravity and few internal defects. It has resistance to many major diseases that contribute to its potential for organic farming and sustainable farming systems.

Technical Abstract: Echo Russet is a medium- to late-maturing selection with long, large, russeted tubers. Total yields are similar to those of Russet Burbank and Ranger Russet, however Echo Russet produced significantly greater yields than Russet Norkotah. Further, Echo Russet produced significantly higher US No. 1 yields when compared to standard varieties. Echo Russet has high protein, high specific gravity, light fry color, low acrylamide level, and few internal and external tuber defects. In three years of evaluations in Western Regional Potato Variety Trials, post-harvest merit scores for fresh and processing qualities were high for Echo Russet when compared to standard varieties. Echo Russet is resistant to Fusarium dry rot, Pectobacterium (syn. Erwinia) soft rot, and common scab. Echo Russet exhibits moderate resistance to Verticillium wilt, early blight, potato virus Y (PVY), potato leaf roll virus (PLRV), potato mop top virus (PMTV), and corky ring spot. The preponderance of resistances to major diseases gives Echo Russet great potential for organic production and sustainable farming systems.
