Variety used for comparison: 'Annabelle'

Summary: The proportion of blue in the anthocyanin colouration of the lightsprout base of 'Delianne' is medium to high whereas it is absent or low in 'Annabelle'. The lightsprout tip of 'Delianne' has a closed habit whereas 'Annabelle' has an intermediate habit. 'Delianne' also has a medium number of root tips on the lightsprout and short lateral shoots whereas 'Annabelle' has a few root tips and long lateral shoots. The foliage structure of 'Delianne' is a leaf type (foliage closed, stems not, or hardly visible) whereas 'Annabelle' is a stem type (foliage open, stem clearly visible). The extent of the anthocyanin colouration at the base of the stem of 'Delianne' is very low whereas the extent is medium along the entire stem for 'Annabelle'. The frequency of coalescence of the terminal and lateral leaflets of 'Delianne' is absent or very low whereas it is high in 'Annabelle'. 'Delianne' has a shorter plant height than 'Annabelle'. 'Delianne' has a high frequency of inflorescences per plant that are medium in size whereas the frequency of inflorescences per plant is low and are small in 'Annabelle'.


LIGHT SPROUT: medium size, ovoid to conical shape, medium number of root tips, short lateral shoots

LIGHT SPROUT TIP: medium size in relation to base, closed habit, weak intensity of anthocyanin colouration, medium pubescence

PLANT: foliage structure is leaf type where foliage is closed and stems are not or hardly visible, semi-upright growth habit, medium maturity

STEM: extent of anthocyanin colouration is very low at the base only

LEAF: medium to large outline, intermediate openness, light to medium green colour, low extent and weak intensity of anthocyanin colouration on the midrib of the upper side
SECOND PAIR OF LATERAL LEAFLETS: large size, narrower than long width in relation to length
LEAFLETS: weak presence of secondary leaflets, absent or very low frequency of coalescence of terminal and lateral leaflets, absent to weak waviness of margin, medium depth of veins, dull to medium glossiness of upper side, no pubescence on blade at apical rosette

INFLORESCENCE: high frequency per plant, medium size, extent of anthocyanin colouration on peduncle is absent or very low
FLOWER BUD: low extent of anthocyanin colouration
COROLLA: medium size, absent or very low extent and absent or very weak intensity of anthocyanin colouration on the inner side, with absent or low proportion of blue

TUBER: long-oval to long shape, light to medium yellow flesh
TUBER EYES: shallow depth
TUBER SKIN: yellow, yellow at base of eye, absent to weak anthocyanin colouration in reaction to light

Origin & Breeding History: The origin of 'Delianne' is the result of the cross made in 1993 between 'Impala' as the female parent and 'Wilja' as the male parent in Emmeloord, The Netherlands. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.

Tests & Trials: Tests and trials for 'Delianne' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres. Plants were spaced 0.30 metres apart.
