General

  • Origin & Breeding: bred from the cross (ND9526-4Russ x ND9687-5Russ) made in 1976 and selected by the North Dakota Agricultural Experiment Station, Fargo, ND, and the USDA Agricultural Research Service. Released in 1987.
  • Year registered in Canada: 1993
  • Registration number: 3831
  • Maturity: early to mid-season

Botanical Features

  • Plants: medium, slightly upright; stems medium thick; nodes not pigmented.
  • Leaves: medium, open, slightly pubescent.
    Terminal leaflets: medium, ovate; tip acuminate; base oblique, asymmetrical.
    Primary leaflets: medium, ovate, generally four pairs.
    Secondary and tertiary leaflets: numerous.
  • Flowers: medium, white corolla; anthers yellow orange; buds slightly pigmented.
  • Tubers: long to slightly oblong, smooth; heavy, dark tan, russeted and netted skin; shallow bright golden eyes, fairly numerous; many slightly curved eyebrows; white flesh.
  • Sprouts: white with some purple pigment at tip.

Agricultural Features

Medium yielding variety, attractive appearance, uniform tuber size and shape. Wide adaptability. Resistant to hollow heart. Low to medium specific gravity. Good storability. Medium dormancy period.

Tuber shape and type are very appropriate for the count-carton market. Not well suited for processing.

  • Utilization: good for baking; poor to moderate for boiling with some after cooking discoloration; poor for chipping.
  • Chief Market: count-carton trade as a baker.

Reaction to Disease

Resistant: Columbia root-knot nematode.
Good resistance: common scab, silver scurf.
Moderately resistant: leaf roll net necrosis, PVY.
Susceptible: most viruses, late blight, early blight, verticillium wilt, potato wart.

Note: this variety has the ability to carry potato virus Y (PVY) without expressing symptoms. In replicated trials, PVY infection of 25% of the plants did not significantly reduce yield, grade or specific gravity. A faint mosaic may be observed under optimum conditions.
