This Smorgasbord takes a look at Highland Russet, which, after seeing a lull in popularity since its introduction in 2006, is seeing a bit of a resurgence, particularly in Canada. A drought-tolerant, light-skinned, mid- to late-season variety used in both the fresh and processing markets, Highland Russet seed acreage in Canada has more than doubled over the past three years.

Strengths

  • High yields with high percentage of U.S. No. 1s
  • Moderately high specific gravity
  • Resistant to second growth, hollow heart and most internal defects
  • Large tubers with excellent conformation and uniformity

Management

  • Nitrogen requirements similar to Russet Burbank
  • Significantly more resistant to water stress-related tuber defects than Russet Burbank
  • Plant water uptake decreases appreciably in late August, so irrigation application rates need to be adjusted according to soil moisture measurements.
  • Vines should be killed two to three weeks before harvest to allow for proper skin maturation and chemical maturity.

Disease Ratings

  • Common scab: moderately resistant
  • PVYO: moderately resistant 
  • Tuber late blight: moderately resistant
  • Verticillium: moderately susceptible
  • Net necrosis: moderately susceptible
  • Soft rot: moderately susceptible
  • Early blight: moderately susceptible
  • PVYN: susceptible
  • Corky ringspot: susceptible
  • Foliar late blight: susceptible
