Potato Association of America. "Red Ruby was selected from the progeny of a cross between Bison x MN11.76-1. It was tested as MN13035 and released by the University of Minnesota Agricultural Experiment Station and Department of Horticultural Science in 1994. Red Ruby is a mid-season red variety for the fresh market. It yields well and has excellent color. Tubers are round to blocky and dark red. The skin is smooth but sometimes slightly netted."
