Variety Description

Variety used for comparison: 'Milva'

Summary: The shape of the lightsprout of 'Georgina' is spherical whereas the shape of the lightsprout of 'Milva' is ovoid. The intensity of anthocyanin colouration of the base of the lightsprout is medium to strong for 'Georgina' whereas the intensity is very strong for 'Milva'. The proportion of blue in the anthocyanin colouration of the base of the lightsprout is medium for 'Georgina' whereas the proportion of blue is high for 'Milva'. The pubescence of the base of the lightsprout is dense for 'Georgina' whereas the pubescence is absent or very sparse for 'Milva'. The intensity of anthocyanin colouration of the tip of the lightsprout is absent or very weak for 'Georgina' whereas the intensity is strong for 'Milva'. The plants of 'Georgina' are taller than the plants of 'Milva'. The anthocyanin colouration of the stem is absent for 'Georgina' whereas the extent of anthocyanin colouration is low for 'Milva'. The size of the outline of the leaf of 'Georgina' is large whereas the leaf of 'Milva' is of medium size. The presence of secondary leaflets is medium to strong for 'Georgina' whereas the presence of secondary leaflets is weak for 'Milva'. In reaction to light, the tuber skin of 'Georgina' develops a medium to strong intensity of anthocyanin colouration whereas the tuber skin of 'Milva' develops an absent or very weak to weak intensity of anthocyanin colouration.

Origin & Breeding History: 'Georgina' originated from a cross conducted in 2001 between the selections designated 'L 96/225/309' and 'E 96/22/53'. It was selected in 2003 for its positive agronomic characteristics.

Tests & Trials: The comparative trial for 'Georgina' 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.
