Variety Description

Varieties used for comparison: 'Shepody', 'Coastal Russet' and 'Russet Burbank'

Summary: The shape of the lateral leaflets of 'AR2006-2' are broadly ovate whereas they are medium ovate in 'Shepody' and 'Coastal Russet' and narrowly ovate in 'Russet Burbank'. The shape of the base of the lateral leaflet of 'AR2006-2' is asymmetrical cordate whereas it is truncate in 'Shepody' and 'Russet Burbank' and lobed in 'Coastal Russet'. The tuber skin of 'AR2006-2' is yellow whereas it is light beige on 'Shepody' and light brown russet on 'Coastal Russet' and 'Russet Burbank'. The tuber skin texture of 'AR2006-2' is rough whereas it is smooth on 'Shepody' and russetted on 'Coastal Russet' and 'Russet Burbank'. The tuber flesh of 'AR2006-2' is light yellow whereas it is white on all of the reference varieties. The pubescence at the base of the light sprout of 'AR2006-2' is absent or very sparse whereas it is dense on 'Shepody' and 'Russet Burbank' and medium on 'Coastal Russet' and 'Russet Burbank'.

Origin & Breeding History: 'AR2006-2' originated through the hybridization of 'Coastal Russet' and 'G11505-02' conducted in Fredericton, New Brunswick in 1998. Initial selections were carried out in 2000. Selection criteria included adaptation, tuber type and french fry quality.

Tests & Trials: The tests and trials for 'AR2006-2' 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.
