Variety used for comparison: 'Belana'

Summary: The lightsprout of 'Antonia' has many root tips whereas the lightsprout of 'Belana' has few root tips. The extent of the anthocyanin colouration is low to medium along the entire stem for 'Antonia' whereas the extent is low and halfway up the stem for 'Belana'. The extent of the anthocyanin colouration is medium to high and the intensity is weak to medium on the upper side of the midrib of the leaf for 'Antonia' whereas the extent is absent or very low and the intensity is absent or very weak for 'Belana'. 'Antonia' has a pubescent leaflet blade at the apical rosette whereas it is glabrous for 'Belana'. The frequency of flowers per plant is medium on 'Antonia' whereas it is absent or very low on plants of 'Belana'. On the inner side of the flower corolla, the extent of anthocyanin colouration is high and the intensity is medium for 'Antonia' whereas the extent of the anthocyanin colouration is absent or very weak and the intensity is absent or very low for 'Belana'. The plants of 'Antonia' mature late whereas those of 'Belana' mature mid-season.

Origin & Breeding History: The variety 'Antonia' originated from a cross between P 92/388 as the female parent and 165/22/65 B as the male parent made in 2000 in Petersgroden near Bockshorn (Lower Saxony), Germany. The variety was selected based on positive agronomic criteria.

Tests & Trials: Trials for 'Antonia' were conducted during the 2013 growing season in Drummond, New Brunswick. Each variety plot 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 between rows. Plants were spaced 0.30 metres apart.
