Markies is a marketable, high-yielding variety with yellow skin and light yellow flesh, suitable for both fingerling potatoes and crisp (chip) production.

  • It features uniform-shaped tubers with shallow eyes and long oval shapes.
  • Thanks to its floury texture and excellent dry matter content, it absorbs minimal oil during frying, making it ideal for crisps and fries.
  • Markies has a very low sugar content.
  • It is susceptible to spraing.
  • Markies is a globally cultivated variety.

Harvest and Dormancy

Harvest: It is recommended to wait at least three weeks after vine kill before harvesting. Markies is sensitive to mechanical damage.

Growing Recommendations

  • Certified seed potatoes should be used.
  • Seed potatoes should not be cut.
  • For seed size 35–45 mm: in-row spacing should be 14–17 cm.
  • For seed size 45–55 mm: in-row spacing should be 17–18 cm.
  • For seed size 55–60 mm: in-row spacing should be 18–23 cm.
  • All planting equipment should be properly disinfected.
  • Seed tubers should be treated with appropriate seed treatment products.
  • Crop rotation practices should be followed.
