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.
