Origin & Breeding History: The variety 'Prince of Orange' originated from a cross made in 2003 between 'Susanne' as the female parent and 'Laura' as the male parent at the HZPC Research & Development Centre in Metslawier, The Netherlands. The variety was selected from the F1 progeny in 2005. Selection criteria included internal and external quality, yield and resistance against different diseases and pests. The testing was conducted in The Netherlands and at different locations abroad.

Tests & Trials: The comparative trial for 'Prince of Orange' 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.
