Variety used for comparison: 'Snowden'

Summary: The lightsprout of 'Sound' is large and broad cylindrical in shape while that of 'Snowden' is very small to small and spherical. The base of the lightsprout of 'Sound' has a very strong intensity of anthocyanin colouration with a high proportion of blue while that of 'Snowden' has an absent or very weak intensity of anthocyanin colouration with an absent or low proportion of blue. The base of the lightsprout of 'Sound' has a medium density of pubescence while that of 'Snowden' has sparse pubescence. The lightsprout of 'Sound' has a medium number of root tips while that of 'Snowden' has few root tips. The stem of 'Sound' has a low to medium extent of anthocyanin colouration along the entire stem while that of 'Snowden' has an absent or very low extent of anthocyanin colouration. The tuber of 'Sound' is oval to long-oval with very shallow to shallow eyes while that of 'Snowden' is round with deep to very deep eyes. The tuber of 'Sound' has yellow skin and medium yellow flesh while that of 'Snowden' has light beige skin and cream coloured flesh.

Origin & Breeding History: 'Sound' (experimental designation CMK2008-622-009) originated from the cross between 'Mondial' and 'CMK2003-707-003' conducted at the C. Meijer breeding station in Rilland, Netherlands in 2007. The new variety was selected and designated CMK2008-622-009 in 2009 based on tuber number, tuber shape, tuber flesh colour and disease resistance.

Tests & Trials: The comparative trial for 'Sound' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2023 growing season. The field trial consisted of a single 15.2 metre long row per variety. Rows were spaced 1.1 metres apart with each row containing 65 plants spaced 0.23 metres apart. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. 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.
