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'.

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.
