King Harry, field trialed as NY131
Parentage: N142-72 x Pike
Released: 2006
Breeder/Agency: Walter De Jong, Ward Tingley, Robert Plaisted/Cornell University

Commentary: King Harry is the result of a decades-long collaboration between the potato breeding program and the department of entomology at Cornell University. It is a hybrid of the wild species Solanum berthaultii and S. tuberosum with short, Type A, sticky leaf hairs (glandular trichomes) which explode a sticky goo miring and impeding small insect pests and thus imparting a natural deterrance to these insect pests. King Harry was named by Jim Gerritson of Wood Praire Farm, Bridgewater, ME. In 2007, this variety received the Green Thumb Award from the Mail-order Growing Association. King Harry is a much improved version of its predecessor Prince Hairy.

 
Production Characteristics:
  • Maturity: Early-mid season, similar to Superior. Full season yield will be 96% of Atlantic
  • Yield: Medium. Marketable yield 313 cwt/acre in 18 field trials over 8 years
  • Specific Gravity: Avg. 1.079; range is 1.052 in NC to 1.086 in ME
  • Tuber set: Heavy. Plant at 8 - 10 inch spacing
  • Nitrogen: For mineral soils: 125 to 150 lbs/acre. For muck soils: 100 lbs/acre
  • Diseases: Very susceptible to common scab. Resists aphids, leafhoppers, flea beetles and potato tuber moths. Deters Colorado potato beetles. Resistant to Ro1 of Golden nematode, PVY and pink rot (Phytophthora erythrosceptica). Few internal and external defects. Large tubers may exhibit hollow heart
  • Storage/dormancy: Stores well; a good keeper. Dormancy is one week longer than Atlantic
  • Market: Round white tablestock, directed toward those growers focused on GMO-free, pesticide-free and organic/natural techniques
