AGRICULTURAL FEATURES

Medium yielding variety; wide adaptability as first early tablestock. Tubers size early to very early across the Canadian Prairies; vines maturity is midseason to late; smooth conformation if harvested early but if left to plant maturity, tubers frequently become oversized and rough with growth cracks or hollow heart. Weak to medium storability; low to medium specific gravity.

REMARK: should be used as an early variety; top killing is recommended to prevent oversized tubers.

  • Utilization: no after cooking discolouration; fair to good for boiling.
  • Chief Market: early fresh market in Western Canada

REACTION TO DISEASES
