Dakota Trailblazer
Dakota Trailblazer (AOND95249-1Russ)
Parentage: A98163-3LS x A8914-4
Developers: The North Dakota Agricultural Experiment Station and North Dakota State
University
Plant Variety Protection: Application in progress
Strengths: High yield of uniform tubers; resistance to sugar ends, cold induced sweetening,
verticillium wilt, and good field resistance to foliar late blight.
Morphological Characteristics
Plant: Pretty, vigorous, medium to large vine with white flowers. Vine is erect and has medium-late maturity.
Tubers: Attractive tubers with medium dark russet skin and long and blocky tuber type; eyes are shallow and tubers have creamy white flesh.
Agronomic Characteristics
Vine Maturity: Medium-late.
Tubers: Long and blocky, with medium dark russet skin and creamy white flesh. Sets fewer tubers than Russet Burbank and sizes quickly. Begin monitoring tuber size in northern production areas by Aug. 1.
Yield Potential: High and produces a high percentage of U.S. No. 1 tubers.
Specific Gravity: High (greater than 1.090 average).
Culinary Quality: Dual-purpose, suitable for both frozen processing and tablestock. Produces mealy baked potatoes, french and steak fries, and wedges.
Diseases/Pests/Physiological Disorders: Resistance to verticillium wilt and sugar ends in field trials. Good field resistance to foliar late blight. Moderate resistance to pink rot. Hollow heart, blackspot bruise, and fusarium dry rot have occasionally been noted.
Storability: Stores well; low sugar accumulation in storage. Processes consistently from 45° F storage and perhaps colder. Dormancy is long.
Cultural Information: Tolerant of metribuzin applications. Requires about 75 lbs./acre less nitrogen than Russet Burbank. Due to high specific gravity, bruise management is important.
Weaknesses: Hollow heart has sometimes been observed. Some susceptibility to black spot bruise and fusarium dry rot.
Incentives for production: High yielding, dual-purpose russet, with excellent appearance and fry quality, low-input cultivar, with resistance to several diseases and abiotic stresses.
Seed Availability: Certified seed is available from producers in North Dakota, Minnesota and Colorado.
