Origin & Breeding History: 'Orlena' originated from a cross conducted in 2000 between 'Emergo' and 'Laura' at HZPC Holland B.V., in Metslawier, Netherlands. 'Orlena' was selected in 2001for its yield, internal and external quality, and resistance against diseases and pests.

Tests & Trials: The comparative trial for 'Orlena' was conducted by Global Agri Services Inc. during the growing season of 2016 in Drummond, New Brunswick. The trial consisted of a single, 19.5 metre long row containing 65 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, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
