Origin & Breeding History: 'AAC Généreuse' (experimental designation LL0312-23) originated from the controlled cross between 'Carlsbad' and 'SJQ-70' made in 2003 by Dr. Shahrokh Khanizadeh at the Agriculture & Agri-Food Canada, Saint-Jean-sur-Richelieu, in Quebec. In 2008, the variety was selected for commercial evaluation. Selection criteria included yield, fruit size, disease resistance, shelf life and fruit colour as it compared to 'Kent' and 'Jewel'.

Tests & Trials: Trials for 'AAC Généreuse' were conducted in Lavaltrie, Quebec during the 2014 growing season. In the spring of 2013, a total of twenty plants were planted. Plants were spaced approximately 40 cm apart along 5 metre rows spaced 1.3 metres apart. Each variety consisted of approximately 250 plants when examined. Measured characteristics were based on 15 measurements.
