This month the Smorgasbord takes a look at Pomerelle Russet, an early-maturing fresh variety showing promise—at least in early trials—out of short- or mid-term storage for the fry processing market. However, its primary use appears to be as a high-quality, early fresh variety. We appreciate our friends at the Potato Variety Management Institute for this information on Pomerelle Russet.

 

Traits

  • Moderately high early-season yields
  • Attractive, smooth, oblong-long tubers with brown-russeted skin
  • Moderately long tuber dormancy, about 30 days shorter than Burbank
  • Maintains acceptable fry color 180 to 200 days in storage at 48 degrees
  • Moderate specific gravity

 

Strengths

  • High percentage of U.S. No. 1s
  • Greater resistance to soft rot, corky ringspot, potato mop-top virus and tuber infections from late blight relative to Burbank and Norkotah
  • Resistances to internal and external defects
  • Lower total glycoalkaloid concentrations and higher protein and vitamin C concentrations than Ranger and Burbank
  • Resistance to sugar ends
  • High protein and vitamin C concentrations
  • Less susceptible to growth cracks, second growth, shatter bruise and hollow heart than Burbank; similar to Ranger and Norkotah
  • Dry rot resistance similar to Norkotah; more resistant than Burbank
  • Significantly lower susceptibility to Fusarium dry rot in storage than Burbank

 

Weaknesses

  • Slightly lower yields than industry standard varieties
  • Susceptible to early dying, PVY, potato leafroll virus and foliar late blight

 

Pomerelle Russet has performed very well in eastern Canada and an exclusive licensing agreement has been made with a company in that region for marketing and production. Information on seed availability for Pomerelle Russet is available from the Potato Variety Management Institute at www.pvmi.org.
