Variety Description

Variety used for comparison: 'Kennebec'

Summary: The intensity of anthocyanin colouration of the base of the lightsprout of 'Evora' is medium whereas the intensity is weak for 'Kennebec'. The habit of the tip of the lightsprout of 'Evora' is intermediate between closed and open whereas the habit of the tip of 'Kennebec' is closed. The plants of 'Evora' are shorter than the plants of 'Kennebec'. The extent of anthocyanin colouration of the stem of 'Evora' is low whereas the extent is absent or very low for 'Kennebec'. The openness of the leaf of 'Evora' is intermediate between closed and open whereas the leaf of 'Kennebec' is open. The presence of secondary leaflets on the leaf of 'Evora' is medium whereas the presence of secondary leaflets is weak for 'Kennebec'. The extent of anthocyanin colouration on the upper side of the leaf midrib of 'Evora' is medium whereas the extent is absent or very low for 'Kennebec'. The anthocyanin colouration on the inner side of the corolla of 'Evora' is of medium to high extent and medium intensity whereas the anthocyanin colouration is absent for 'Kennebec'.

Description:

PLANT: foliage structure is intermediate type where foliage is half open and stems are partly visible, semi-upright growth habit, mid-season to late maturity

STEM: low extent of anthocyanin colouration along entire length

LEAF: outline is medium size, openness is intermediate between closed and open, light green on upper side, medium extent and weak intensity of anthocyanin colouration on upper side of midrib, medium presence of secondary leaflets, absent or very low frequency of coalescence of terminal and lateral leaflets
SECOND PAIR OF LATERAL LEAFLETS: medium size, leaflet is narrower than long
LEAFLET: strong waviness of margin, medium depth of veins, dull upper side, glabrous blade at apical rosette

INFLORESCENCE: medium frequency per plant, small
PEDUNCLE: medium extent of anthocyanin colouration
FLOWER BUD: medium extent of anthocyanin colouration
COROLLA: medium size
COROLLA (INNER SIDE): medium to high extent of anthocyanin colouration, medium intensity of anthocyanin colouration, absent or low proportion of blue in anthocyanin colouration

TUBER: short oval shape, white flesh
TUBER EYE: medium depth, yellow at base
TUBER SKIN: yellow, develops medium intensity of anthocyanin colouration in reaction to light

Origin & Breeding History: 'Evora' originated from a cross conducted at HZPC Research and Development in Metslawier, Netherlands, in 2000, between the varieties 'Lee 92-166', as the female parent, and 'Valor', as the male parent. The resulting seedlings were tested in the Netherlands and at different testing locations abroad. 'Evora' was selected in 2000 for its yield, internal and external quality, and resistance to different diseases and pests.

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