Tee, I believe it was Georgia Jet. It has been trialed in Cottage Grove, Or at Territorial Seed Company, which isn't far from us. We bought the slips from them.
Here is curing instructions:
Cure sweet potatoes by holding them for about 10 days at 80-85°F and high relative humidity (85-90 percent). In the absence of better facilities, they can be cured near a furnace to provide warmth. If the temperature near your furnace is between 65-75°F, the curing period should last 2-3 weeks. To maintain the required high humidity (85-90 percent relative humidity), stack storage crates or boxes and cover them with paper or heavy cloth. Packing in perforated plastic bags will also keep humidity high, yet the perforations will allow excess moisture to escape.
Once the sweet potatoes are cured, move them to a dark location where a temperature of about 55-60°F can be maintained during storage. Sweet potatoes are subject to chilling injury, so keep them out of the refrigerator. Outdoor pits are not recommended for storage because the dampness encourages decay. Good results can be obtained by wrapping cured sweet potatoes in newspaper and storing them in a cool closet.
