Blazer Russet is an early maturing, dual-purpose russet with excellent processing qualities developed by the Tri-State Breeding and Research program and PVP-applied for in 2006. Russet was recently accepted by McDonald’s for production of the fast-food chain’s french fries. The variety is currently grown primarily in Maine and eastern Canada. A full list of Blazer Russet seed growers can be found at www.pvmi.org.

A7816 × Norking Russet

 

Key Attributes

  • Early yield and grade, good alternative to Shepody
  • Outstanding culinary qualities
  • Resistant to external defects
  • Attractive appearance for fresh pack
  • Resistance to black spot bruise similar to Russet Burbank, better than Ranger Russet

 

Management

  • Optimal seed piece spacing for 36-inch rows is 9 to 11 inches with a planting depth 5 to 6 inches. Blazer Russet has an intermediate number of uniformly distributed eyes. Seed piece size should range from 2 to 3 ounces.
  • Requires 90 to 100 percent of nitrogen required for Russet Burbank (200 to 220 pounds per acre in southeastern Idaho). However, a higher proportion of the seasonal nitrogen requirement should be applied early in the growing season to support its earlier tuber development. Typically, one‐half to two‐thirds of the total nitrogen requirement should be applied by row closure, with subsequent in‐season applications made via sprinkler irrigation based on petiole nitrate concentrations. 
  • Seasonal irrigation requirements  similar to those for Russet Burbank
  • Resistant to water stress-related tuber defects. Available soil moisture should be maintained within the range of 65 to 80 percent 

 

Storage

  • Tuber dormancy 40 to 50 days shorter than Russet Burbank
  • In the absence of tuber dry rot problems, can be stored up to nine months for processing or fresh market uses. 
  • Good resistance to metribuzin when applied at labeled rates
