Potato

Variety Description

Varieties used for comparison: 'Cecile' and 'Eileen'

Summary: The lightsprout of 'Carminelle' is ovoid in shape whereas that of 'Cecile' is broad cylindrical. The base of the lightsprout for 'Carminelle' has an absent or low proportion of blue in the anthocyanin colouration whereas that of 'Eileen' has a medium proportion of blue in the anthocyanin colouration. The lightsprout tip of 'Carminelle' has a closed habit whereas that of 'Cecile' has an intermediate habit. The lightsprout tip of 'Carminelle' has an absent or very weak to weak intensity of anthocyanin colouration whereas that of the reference varieties have a medium intensity. The plants of 'Carminelle' are shorter than the plants of the reference varieties.

Origin & Breeding History: 'Carminelle' originated from a cross between 'Cecile', as the female parent, and 'Cherie', as the male parent, conducted in 2003 at the HZPC Research B.V. in Metslawier, Netherlands. 'Carminelle' was selected from the resulting F1 in 2004, based on yield, internal and external tuber quality, and disease resistance.

Tests & Trials: The comparative trial for 'Carminelle' was conducted by Global Agri Services Inc. during the 2019 growing season in Drummond, New Brunswick. The trial consisted of a single, 21 metre long row per variety. Each row contained 70 plants spaced 0.3 metres apart with an inter-row spacing of 0.9 metres. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean differences were significant at the 5% probability level based on a paired Student's t-test.
