Origin & Breeding History: 'AR2007-2' (experimental designations 13740-18 and F02032) originated from the cross of 'F91031' and 'ND860-2' made in 2000 in Fredericton, New Brunswick. Selection criteria were clonal selection for adaptation, tuber type and cold temperature chipping quality.
Tests & Trials: Trials for 'AR2007-2' 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.
