Jiwan Palta, Felix Navarro, Bryan Bowen

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in a red skin potato variety that retains color in storage and shows excellent internal and external quality.
OVERVIEWGrowers of red skin potatoes continue to search for a variety that retains skin structure and color for several months at 38 degrees Fahrenheit. Dark Red Norland, the standard variety at present, does not store well several months after harvest and loses color.
THE INVENTIONUW–Madison researchers have developed W8893-1R, a red potato variety with very smooth and uniform tubers, round-oval shape, shallow eyes and attractive coloring that maintains well in storage.

The new variety is available through the Wisconsin Crop Improvement Association.
  • Potato production for the fresh market
  • Superior storage characteristics
  • Smoother skin, shallower eyes and comparable yield to Dark Red Norland
STAGE OF DEVELOPMENTField tests have shown excellent tuber shape, size, color and storage ability at 38 degrees Fahrenheit through February.
