Interpretive Summary:

Technical Abstract: Dakota Trailblazer, a new, full-season, dual-purpose cultivar was released in 2009 by the North Dakota Agricultural Experiment Station. It has medium russet skin, white to creamy flesh, and long and blocky tuber type. Dakota Trailblazer originated from the cross of A89163-3LS x A8914-4, parental selections of the USDA-ARS potato breeding program at Aberdeen, ID in 1995. It was evaluated as AOND95249-1Russ. The single-hill was selected at Dawson, ND in 2000; it was evaluated for eight years in North Dakota state-wide trials and at many North American locations. Yield potential is medium-high, with marketable yield and percent marketable superior to Russet Burbank. Specific gravity is significantly higher than Russet Burbank, averaging 1.091. In field trials Dakota Trailblazer has required about 67 kg/ha less N than Russet Burbank. It produces few tubers per hill and a 25.0-30.5 cm within-row spacing may maximize production of US No. 1 tubers. Advantages of Dakota Trailblazer include resistance to Verticillium wilt, sugar ends, and cold sweetening. It has moderate resistance to pink rot caused by Phytophthora erythroseptica Pethyb. and demonstrates field resistance to late blight. It is susceptible to Fusarium dry rot, and hollow heart and blackspot bruise are occasionally noted. Seed increases and commercial evaluation of Dakota Trailblazer have been conducted in North Dakota, Minnesota, and Colorado. Dakota Trailblazer is the first cultivar released from the North Dakota State University potato breeding program that is suitable for production of French fries.
