Variety Description

Variety used for comparison: 'Anouk'

Summary: The lightsprout of ‘Jacky' has a medium number of root tips while that of ‘Anouk' has few root tips. The base of the lightsprout of ‘Jacky' has a medium intensity of anthocyanin colouration and medium density of pubescence while that of ‘Anouk' has an absent or very weak intensity of anthocyanin colouration and very sparse to sparse pubescence. The terminal and lateral leaflets of ‘Jacky' have a medium frequency of coalescence while those of ‘Anouk' have an absent or very low frequency of coalescence. The corolla of ‘Jacky' has a medium extent of medium intensity anthocyanin colouration while that of ‘Anouk' has an absent or very low extent of absent or very weak intensity anthocyanin colouration.

Origin & Breeding History: 'Jacky' (experimental designation SW 09-0557) originated from the cross between ‘Anouk' as the female parent and 'Athlete' as the male parent, conducted at the Lantmännen Seed B. V. breeding station in Emmeloord, Netherlands in 2008. One of the resulting progeny was designated SW 09-0557 in 2010 based on tuber shape, tuber number, tuber appearance, and disease resistance.

Tests & Trials: The comparative trial for 'Jacky' was conducted by Global Agri Services Inc. in Central Blissville, New Brunswick during the 2024 growing season. The field trial consisted of a single 14.86 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.
