Summary: 'FV12228-5' has a shorter plant with a more upright growth habit than 'Russet Burbank' and 'Shepody'. The nodes of the stem of 'FV12228-5' have a higher degree of swelling than the reference varieties. 'FV12228-5' has a darker green leaf colour than 'Russet Burbank'. The leaf silhouette of 'FV12228-5' is open while it is intermediate in 'Russet Burbank'. 'FV12228-5' has a terminal leaflet shape of narrowly ovate while it is elliptical in 'Russet Burbank' and broadly ovate in 'Shepody'. The flower colour of 'FV12228-5' is red-violet while it is white in 'Russet Burbank'. The anthocyanin colouration on the inner surface of the corolla of 'FV12228-5' is stronger than the reference varieties. 'FV12228-5' has a larger corolla than the reference varieties. The tuber of 'FV12228-5' is oblong with a light beige skin colour and a smooth to netted texture while it is elliptical with a reddish brown skin colour and a russetted texture for 'Russet Burbank'. 'FV12228-5' has a light sprout base with a strong to very strong anthocyanin colouration and a high proportion of blue in it while in the light sprout base of 'Russet Burbank' there is medium anthocyanin colouration with no blue colour in it and in 'Shepody' there is weak anthocyanin colouration with no blue colour in it. 'FV12228-5' has stronger anthocyanin colouration and more root tips of the light sprout tip than the reference varieties.

Origin & Breeding History: 'FV12228-5' is the result of the cross F88051 x Wischip that was made in 1995 at the Agriculture & Agri-Food Canada Potato Research Centre, Fredricton, New Brunswick. F88051 = F72022 x Russette and Wischip = Wis 55.232.58 x Wis 231. It was assigned to AAFC-Lethbridge where the first 2 years (1996-1997) of selection were carried out at the Benton Ridge Research Substation. Subsequent evaluation occurred in the Western Canadian Regional Potato Trials in 2001-2003, multi-harvest and long term storage trials in 2002-2003 at the Vauxhall Research Station. Selection criteria included tuber shape, tuber size, vine maturity, yield, incidence of tuber defects, fry colour and dry matter content (specific gravity).

Tests & Trials: Tests and trials occurred during the summer of 2007 in Vauxhall, Alberta. Plots consisted of a row 7.6 metres long with plants spaced 30 cm apart within the row. Rows were spaced 91 cm apart. There were 3 replicates arranged in an Randomized Complete Block design.
