Variety Description

Variety used for comparison: 'Russet Burbank'

Summary: The lightsprout of 'Teton Russet' is ovoid, medium sized and has a medium number of root tips whereas the lightsprout of 'Russet Burbank' is spherical, small to medium sized and has few root tips. The intensity of anthocyanin colouration at the base of the lightsprout is very strong for 'Teton Russet' with a high proportion of blue whereas the intensity is medium to strong with a proportion of blue as absent or low for 'Russet Burbank'. The lightsprout tip of 'Teton Russet' has an intermediate habit whereas it has a closed habit in 'Russet Burbank'. The intensity of anthocyanin colouration at the tip of the lightsprout is strong for 'Teton Russet' whereas the intensity is absent to weak for 'Russet Burbank'. 'Teton Russet' has high extent of anthocyanin colouration halfway up the stem whereas it is of medium extent along the entire stem for 'Russet Burbank'. The waviness of the leaflet margins for 'Teton Russet' is medium to strong whereas it is absent or very weak in 'Russet Burbank'. The leaflet blade at the apical rosette is glabrous for 'Teton Russet' whereas it is pubescent in 'Russet Burbank'. 'Teton Russet' has a shorter plant height than 'Russet Burbank'. The frequency of flowers per plant is absent or very low for 'Teton Russet' whereas it is low for 'Russet Burbank'. The plants of 'Teton Russet' mature early to mid-season whereas those of 'Russet Burbank' mature late to very late. The tubers of 'Teton Russet' have a long-oval to long shape with eyes at a shallow depth whereas the tubers of 'Russet Burbank' are long with eyes at a medium depth.

TUBER SKIN: reddish brown, absent to weak anthocyanin colouration in reaction to light

Origin & Breeding History: The variety 'Teton Russet' originated from a cross between 'Blazer Russet' as the female parent and 'Classic Russet' as the male parent, made at the University of Idaho's Aberdeen Research and Extension Center in 2000. The variety was selected as a seedling in the field in 2001 at the Tetonia Research and Extension Center in Idaho. Selection criteria were negative mass selection for agronomic characteristics and resistance to various diseases.

Tests & Trials: Trials for 'Teton Russet' were conducted during the 2013 growing season in Drummond, New Brunswick. Each variety plot consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.30 metres apart. The measured characteristics were based on 10 measurements per variety. Mean differences were significant at the 5% probability level based on a paired StudentÂ’s t-test.
