Origin & Breeding History: 'AR2006-1' originated through the hybridization of 'F89117' and 'ND6993-13' conducted in Fredericton, New Brunswick in 1996. Initial selections were carried out in 2000. Selection criteria included adaptation, tuber type and french fry quality.

Tests & Trials: The tests and trials for 'AR2006-1' were conducted at the Potato Research Centre, Agriculture and Agri-Food Canada, Fredericton, New Brunswick during the summer of 2008. The trials consisted of 2 replicates per variety, ranging from 20 to 25 plants per replicate, measuring approximately 11 metres in length. Measured characteristics were based on 10 measurements. Colour determinations were made using the RHS colour chart, 4th edition, 2001.
