This article appears in the January 2017 issue of Potato Grower.

This month, we’ll take a look at Modoc, a bright red-skinned fresh market variety developed by the Tri-State Breeding and Research Program and released in 2006. Modoc is grown relatively extensively in the Pacific Northwest, Colorado, North Dakota and Canada. A full list of seed growers can be found at www.pvmi.org.

 

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
