Variety Description

Variety used for comparison: 'Russet Burbank'

Summary: The lightsprout of 'AAC Splendor Russet' is conical shaped whereas it is ovoid for 'Russet Burbank'. The lightsprout tip of 'AAC Splendor Russet' has an open habit whereas 'Russet Burbank' has a closed habit. The pubescence of the lightsprout is medium at the base and tip for 'AAC Splendor Russet' whereas it is dense for 'Russet Burbank'. 'AAC Splendor Russet' has an upright growth habit whereas it is semi-upright for 'Russet Burbank'. The extent of anthocyanin colouration of the flower bud is absent for 'AAC Splendor Russet' whereas it is of medium extent for 'Russet Burbank'. The plants of 'AAC Splendor Russet' mature mid season while those of 'Russet Burbank' are late maturing.

Origin & Breeding History: 'AAC Splendor Russet' (experimental designations 'CV01236-3' and 'CO01236') originated from a cross made at the San Luis Valley Research Farm, Colorado State University, USA in 2001 between the female parent designated 'AO92128-4.2' and the male parent designated 'CO95007-1'. In 2002, true potato seed was sown in a greenhouse at Colorado State University and the resulting seedling tubers were planted in 2003 at the Vauxhall Research Substation of Agriculture and Agri-Food Canada in Vauxhall, Alberta. A clone designated 'CV01236-3' was selected in 2003, and progressed through 4-hill, 10-hill, and 50-hill generation stages of selection and evaluation at Vauxhall in 2004, 2005 and 2006, respectively. Selection criteria included vine maturity, shape and size of tuber, specific gravity, culinary quality, fry colour at harvest and out of long-term storage, incidence of tuber defects, and reaction to diseases including common scab, late blight, fusarium dry rot and verticillium wilt. 'CV01236-3' was further evaluated in the Western Canadian Regional Potato Trials from 2007 to 2008.

Tests & Trials: The comparative trial for 'AAC Splendor Russet' was conducted during the 2014 growing season at the Agriculture and Agri-Food Potato Research Centre in Fredericton, New Brunswick. The trial consisted of 2 replicates with 30 plants per variety in each replicate, grown in two 7.5 metre length rows spaced 90 centimetres apart. Plants were spaced 25 centimetres apart in the row. Measurements were taken from 10 plants, or parts of plants, of each variety.
