General

  • Origin & Breeding: bred by F. Lauer at the University of Minnesota from the cross (Neb 16.55-1 x MN 1106.64-1) in St. Paul, Minnesota, in 1970. Released in 1984.
  • Year registered in Canada: 1997
  • Registration number: 4488
  • Maturity: mid-season

Botanical Features

  • Plants: medium large, compact, upright; stems medium size; nodes not pigmented; internodes short and green; wings prominent and strait.
  • Leaves: yellowish green, glossy, long, rigid, almost no pubescence.
    Terminal leaflets: lobed, slightly cupped, smooth, glossy; petioles and midribs not pigmented.
  • Flowers: inflorescence upright, symmetrical; small white corolla; yellow anther; green flower bud.
  • Tubers: oblong, smooth; white skin, may develop russeting under certain conditions; shallow eyes; white flesh.
  • Sprouts: white

Agricultural Features

High yielding variety. Medium specific gravity. Long dormancy period; very good storability. Early production of large tubers; very low incidence of hollow heart. Seems well adapted to both heavy dry land soils and peat soils. During trials, its performance has been mediocre on irrigated sands. If hollow heart or common scab is a problem, this cultivar could be a suitable alternative.

NOTE: this variety has an extreme sensitivity to metribuzin even when applied before emergence or at less than the recommended rate.

  • Utilization: acceptable for boiling and baking; excellent for french frying and flakes. Since it produces large tubers early, it may be useful in the early startup of french fry plants.
  • Chief Markets: processing for french fries early in the season, good potential for fresh market.

Reaction to Diseases

Resistant: common scab, hollow heart.
Susceptible: verticillium wilt, PVS, PVX, PVY, leaf roll, early blight, late blight.
