General

  • Origin & Breeding: bred by Robert L. Plaisted, Cornell University, Ithaca, New York, from a cross made in 1986 between Steuben and bulk pollen from clones that were neotuberosum x tuberosum hybrids. Most of the clones were considered resistant to PVY and golden nematode Ro1.
  • Year registered in Canada: 2010
  • Registration number: 6783
  • Maturity: mid-season

Botanical Features

  • Plants: medium height, semi-erect; stems weakly pigmented; prominent waived single wings; nodes swollen.
  • Leaves: medium green, closed; midribs and petioles not pigmented.
    Terminal leaflets: ovate; tip cuspidate; base obtuse.
    Primary leaflets: three pairs; ovate; tip cuspidate; base cordate.
  • Flowers: medium frequency, corolla white on both surfaces, medium size; orange anthers; flower buds weakly pigmented; calyxes and peduncles light green.
  • Tubers: round to slightly oval; smooth white skin; shallow eyes, predominantly apical; white flesh.
  • Sprouts: spherical; red-violet; base moderately pubescent, strongly pigmented; tip weakly pubescent, weakly pigmented, closed habit.

Agricultural Features

Medium yielding variety of very attractive appearance; well shaped and uniform sized tubers; good resistance to internal defects such as hollow heart and internal necrosis. Long dormancy period; good storage capability. High specific gravity.

Remark: pre-cutting or warming seed is recommended.

  • Utilization: good for boiling and baking, acceptable chip color; slight darkening after boiling (similar to Superior).
  • Chief Markets: fresh market and chips.

Reaction to Diseases

Resistant: golden nematode (Globodera rostochiensis Ro1).
Highly resistant: PVX, PVY.
Moderately resistant: early blight, corky ringspot (Tobacco rattle virus symptoms), powdery scab.
Moderately susceptible: common scab.
Susceptible: late blight.
