GENERAL

• Origin & Breeding: bred by the Agriculture Canada Research Station from the cross (F61101 x F60034) in Fredericton, New Brunswick (Canada) in 1966.
• Registration in Canada: deregistered
• Maturity: very late

BOTANICAL FEATURES

• Plants: very large, upright; stems not pigmented; wings not prominent; nodes not swollen.
• Leaves: grey-green, semi-open, pubescent; midribs pubescent and not pigmented; petioles glabrous and not pigmented.
  Terminal leaflets: broadly ovate; tip acute; base cordate and symmetrical.
  Primary leaflets: four to five pairs; short petiolule; narrowly ovate; tip acute; base cordate and symmetrical.
• Flowers: late and abundant bloom; white corolla; yellow-orange anthers; flower buds not pigmented.
• Tubers: oblong; smooth yellow skin; shallow eyes; light yellow flesh.
• Sprouts: spherical, green, no pubescence.

AGRICULTURAL FEATURES

High yielding variety; early tuber set; extremely high resistance to late blight; susceptible to hollow heart. Good storability; very long dormancy period; medium-high specific gravity.

Remark: under eastern Canadian conditions, heavy roots and tubers often clinging to stolons make harvesting more difficult than with most cultivars.

• Utilization: good to excellent for boiling, baking, chipping and french frying.
• Chief Markets: seed export, processing.

REACTION TO DISEASES

Very high resistance: late blight.
Moderately resistant: PVY, leafroll, rhizoctonia.
Moderately susceptible: common scab.
Susceptible: fusarium dry rot, phoma.
