KEY ATTRIBUTES
• High marketable yields
• Excellent fresh culinary quality
• Skin color that does not fade in storage
• Low internal defects
• Early maturity
PARENTAGE
• ND1196-2R × ND2225-1R
MANAGEMENT
• 9- to 10-inch seed-piece spacing for
greater uniformity in tuber size
• Rapid, uniform emergence
• Sensitive to Metribuzin
• Fertilization: 160 to 180 units of
nitrogen; around 80 of phosphorus;
180 to 200 of potassium
• Harvest: Maintain good soil moisture
after vine kill to promote skin set.
Drying soil too much after vine kill
and then irrigating to facilitate harvest
might actually un-set the skins and
increase skinning issues.
STORAGE:
• Medium storage capability with
dormancy between 100 and 145 days
