The tuber skin of 'AR2006-1' is yellow whereas it is light beige on 'Shepody' and light brown russet on 'Coastal Russet' and 'Russet Burbank'. The texture of the tuber skin of 'AR2006-1' is netted whereas it is smooth on 'Shepody' and 'Kennebec' and russetted on 'Coastal Russet' and 'Russet Burbank'. The pubescence on the light sprout base of 'AR2006-1' is absent or very sparse whereas it is dense on 'Shepody' and medium on 'Coastal Russet', 'Russet Burbank' and 'Kennebec'. The tip of the light sprout of 'AR2006-1' is smaller than the base whereas the tip is equal in size to the base on 'Shepody', 'Coastal Russet' and 'Russet Burbank'. The intensity of anthocyanin colouration on the light sprout tip of 'AR2006-1' is weak whereas it is absent to very weak on all of the reference varieties. Pubescence on the light sprout tip of 'AR2006-1' is sparse whereas it is medium on 'Shepody' and strong on 'Coastal Russet' and 'Russet Burbank'.

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.
