Origin & Breeding History: 'AR2007-3' (experimental designations 13805-03 and P02041) originated from the cross of 'AC Blue Pride' and 'Redsen' made in 1994 in St-Johns, Newfoundland and Labrador (selected in New Brunswick by Agnes Murphy). Selection criteria were clonal selection for adaptation, tuber type and niche chipping potential.
Tests & Trials: Trials for 'AR2007-3' were conducted at Potato Research Centre, Fredericton, New Brunswick, in 2009. There were two replicates of 30 plants with a plant spacing of 30 cm.
