- Year registered in Canada: 1993
- Registration number: 3823
- Maturity: late.
Botanical Features
- Plants: medium to tall, semi-erect; stems weakly pigmented; single wavy and very prominent wings; slightly swollen nodes, not pigmented.
- Leaves: medium green, open; midribs weakly pigmented.
Terminal leaflets: narrowly ovate; tip acuminate; base obtuse and symmetrical; weakly wavy margins.
Primary leaflets: four pairs; narrowly ovate; tip acuminate; base obtuse and asymmetrical. - Flowers: numerous, medium red-violet corolla; lemon yellow anther; flower bud strongly pigmented.

Agricultural Features
Medium to high yielding variety; very resistant to heat necrosis and hollow heart; very susceptible to blackspot bruises; moderately susceptible to growth cracks. Good storability; short dormancy period; high specific gravity.
Resistant to metribuzin herbicide. Requires a long period after wine dessication to achieve good skin set. When intended for french fries, store at 7 to 8 °C and maintain high humidity; should not be stored beyond late February for processing as french fries. Seed potatoes should be stored at 2 to 3 °C to prevent excessive aging and sprouting.
- Utilization: no boiling sloughing and no after cooking discoloration; good for baking and early french frying.
- Chief Markets: fresh market, french fries.
Reaction to Diseases
Good resistance: verticillium wilt, PVY, PVX.
Moderately resistant: early blight, common scab, leafroll, fusarium dry rot.
Highly susceptible: late blight, Root-knot nematode.
