Variety Description

Variety used for comparison: 'Elmo'

Summary: The lightsprout of 'Autumn Rose' is small to medium in size and ovoid in shape while that of 'Elmo' is large and broad cylindrical. The base of the lightsprout of 'Autumn Rose' has a very strong intensity of anthocyanin colouration and sparse pubescence while that of 'Elmo' has a medium to strong intensity of anthocyanin colouration and dense pubescence. The tip of the lightsprout of 'Autumn Rose' is medium in size relative to the base while that of 'Elmo' is small relative to the base. The tip of the lightsprout of 'Autumn Rose' has an intermediate habit, an absent or very weak to weak intensity of anthocyanin colouration and a medium density of pubescence while that of 'Elmo' has a closed habit, a strong intensity of anthocyanin colouration and dense pubescence. The stem of 'Autumn Rose' has a high extent of anthocyanin colouration while that of 'Elmo' has a low extent of anthocyanin colouration. The plants of 'Autumn Rose' are taller than those of 'Elmo'.

Origin & Breeding History: 'Autumn Rose' (experimental designation KW10-384) originated from a cross conducted between BRS 94-164, as the female parent, and 'Cecile', as the male parent, in the Aardappelkweekbedrijf S. Brunia breeding program in Kraggenburg, Netherlands in 2010. Seed from the cross was grown in a greenhouse in 2011 with the resulting tubers planted in the field in Kraggenburg, Netherlands in 2012. KW10-384 was selected in 2013 based on time of maturity, yield, disease resistance, storability and cooking quality.

Tests & Trials: The comparative trial for 'Autumn Rose' was conducted by Global Agri Services Inc. during the 2021 growing season in Central Blissville, New Brunswick. The field trial consisted of a single, 20 metre long row per variety. Each row contained 65 plants spaced 0.3 metres apart with inter-row spacing of 1.1 metres. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean difference was significant at the 5% probability level based on a paired Student's t-test. Lightsprout characteristics were assessed on 10 tubers harvested from the comparative trial and observed approximately 2.5 to 3 months after sprouting was promoted by exposing the tubers to an external agent.
