Origin & Breeding History: 'Red Apple' originated from a cross conducted in 2000 between 'Fontenotte' and 'Romanze' as part of a breeding program by Piet H Smeenge in Emmeloord, Netherlands between. 'Red Apple' was selected in 2003 for its positive agronomic characteristics.
Tests & Trials: The comparative trial for 'Red Apple' 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.
