Variety Description

Varieties used for comparison: 'Vanilla' and 'Primabelle'

Summary: The lightsprout of ‘Sensation' is very small to small and spherical while that of ‘Primabelle' is large and broad cylindrical. The base of the lightsprout of ‘Sensation' has a medium intensity of anthocyanin colouration while that of ‘Primabelle' has a weak intensity of anthocyanin colouration. The base of the lightsprout of ‘Sensation' has an absent or low proportion of blue in the anthocyanin colouration while those of the reference varieties have a medium proportion of blue in the anthocyanin colouration. The base of the lightsprout of ‘Sensation' has sparse pubescence while that of ‘Vanilla' has dense pubescence. The lightsprout of ‘Sensation' has medium to many root tips while that of ‘Primabelle' has few to a medium number of root tips. The stem of ‘Sensation' has a low to medium extent of anthocyanin colouration halfway up the stem while the stem of ‘Vanilla' has a medium extent of anthocyanin colouration along the entire stem and that of ‘Primabelle' has an absent or very low extent of anthocyanin colouration. The plants of ‘Sensation' are shorter than those of ‘Vanilla'. The tuber of ‘Sensation' has medium yellow flesh while those of the reference varieties have light yellow flesh.

Origin & Breeding History: 'Sensation' (experimental designation TE06-02-01) originated from the cross between ‘TE 93-26-02' as the female parent and ‘TE 98-05-31' as the male parent conducted at the Handels Temmerman breeding station in Medemblik, Netherlands in 2006. One of the resulting progeny was selected and designated TE06-02-01 in 2007 based on tuber type and shape, tuber number and disease resistance.

Tests & Trials: The comparative trial for ‘Sensation' 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. 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.
