Agricultural Features

Medium yielding variety; high tuber set resulting in many uniform shaped tubers of medium sized. Performs well on well drained heavy soils; very intolerant to drought. Good field tolerance to potato flea beetle; good resistance to hollow heart, internal necrosis and vascular discoloration; slightly susceptible to growth cracks. Good storability; short dormancy period; medium-high specific gravity.

REMARKS: since tubers set high in hill, it is recommended that a large hill be formed early with a final hilling after tubers are set to avoid sunburn.

  • Utilization: good for boiling, baking and french frying; excellent for chipping.
  • Chief Market: chipping
