Variety Description

Variety used for comparison: 'Belana'

Summary: The lightsprout of 'Concordia' has many root tips and dense pubescence at the base whereas the lightsprout of 'Belana' has a medium number of root tips and sparse pubescence at the base. The plant of 'Concordia' is taller than the plant of 'Belana'. The leaf of 'Concordia' is medium to large whereas the leaf of 'Belana' is small to medium size. The extent of anthocyanin colouration of the midrib of the upper side of the leaf of 'Concordia' is low whereas the extent is absent or very low for 'Belana'. The leaflet margin of 'Concordia' has absent or very weak waviness whereas the leaflet margin of 'Belana' has weak to medium waviness. At the apical rosette, the leaflet blade of 'Concordia' is pubescent whereas the leaflet blade of 'Belana' is glabrous. The frequency of inflorescences per plant of 'Concordia' is low whereas the frequency is absent or very low for 'Belana'. In reaction to light, the tuber skin of 'Concordia' develops a medium intensity of anthocyanin colouration whereas the tuber skin of 'Belana' develops a weak intensity of anthocyanin colouration.

Description:

FLOWER BUD: medium extent of anthocyanin colouration
COROLLA: medium size, absent or very low extent and absent or very weak intensity of anthocyanin colouration on inner side, absent or low proportion of blue in anthocyanin colouration on inner side

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

Origin & Breeding History: The variety 'Concordia' originated from a cross made in 1999 between the selections designated 'BD 1019/2/95' as the female parent and '696/92 L' as the male parent in Böhlendorf (Mecklenburg-West Pomerania), Germany. In 2001, the variety was selected in Böhlendorf based on positive agronomic criteria.

Tests & Trials: The comparative trial for 'Concordia' was conducted during the growing season of 2014 in Drummond, New Brunswick. The trial consisted of a single row with 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 of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
