Origin & Breeding History: The origin of 'Red Lady' is the result of the cross made in 1994 between YP-86-150 and 'Velox' at the breeding station in Windeby, Schleswig-Holstein, Germany. The selection criteria included leaf type, maturity, tuber quality and yield.

Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
