Origin & Breeding History: 'AR2009-10' (experimental designations F05078 and 15068-20) originated from the cross of 'F91031' and 'Congo' made in 2003 in Fredericton, New-Brunswick. Selection criteria were clonal selection for adaptation, tuber type, pigmented flesh and niche French fry potential.

Tests & Trials: Trials for 'AR2009-10' were conducted at the Potato Research Centre, Fredericton, New-Brunswick, in 2010. There were two replicates of 30 plants with a plant spacing of 25cm.
