Origin & Breeding History: 'SP213' is the result of the cross of Allegany x E55-35 made in 1989 in Ithaca, New York, USA. An initial population of 45,000 seedling tubers were planted and evaluated in Alliston, Ontario in 1991. Clones were selected and planted as single hills in 1992 with subsequent selections planted as 5 hills in 1993 and then as 20 hills in 1994. Selection criteria included tuber quality, adaptation, yield, resistance and processing traits.

Tests & Trials: Trials were conducted in Alliston, Ontario in 2008. Plots consisted of 2 rows, with a row length of 6 meters, a plant spacing of 30 cm within the row and a row spacing of 1 meter. There were 30 plants per plot. There were two replicates.
