Variety used for comparison: 'Anuschka'
Summary: The proportion of blue in the anthocyanin colouration of the base of the lightsprout is high for 'Mariette' whereas the proportion of blue is absent or very low for 'Anuschka'. The plants of 'Mariette' are shorter than the plants of 'Anuschka'. The openness of the leaf of 'Mariette' is intermediate between closed and open whereas the leaf of 'Anuschka' is open. The extent of anthocyanin colouration on the upper side of the leaf midrib of 'Mariette' is low to medium whereas the extent is high for 'Anuschka'. The frequency of coalescence of the terminal and lateral leaflets of 'Mariette' is low whereas the frequency of coalescence is medium for 'Anuschka'. The anthocyanin colouration on the inner side of the corolla of 'Mariette' is of absent or very low extent and absent or very weak intensity whereas the anthocyanin colouration is of medium extent and weak intensity for 'Anuschka'. The shape of the tuber of 'Mariette' is short oval whereas the shape of the tuber of 'Anuschka' is oval to long oval.

TUBER EYE: shallow to medium depth, yellow at base
TUBER SKIN: yellow, develops medium to strong intensity of anthocyanin colouration in reaction to light
Origin & Breeding History: 'Mariette' originated from a cross conducted in 2001 between the selections designated 'L 80/93/33' and 'L 96/496/499'. It was selected in 2003 for its positive agronomic characteristics.
Tests & Trials: The comparative trial for 'Mariette' was conducted during the growing season of 2015 in Drummond, New Brunswick. The trial consisted of a single, 18.5 metre long row containing 60 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
