Origin & Breeding History: 'CRPTQ Joany' originated from a cross made between the female parent variety 'Satina' and the male parent variety 'NY 88' at Les Buissons Research Centre in Pointe-aux-Outardes, Quebec, Canada in 2009. In 2011, the variety was first selected in the field in Pointe-aux-Outardes, Quebec based on its appearance, agronomic qualities, specific gravity, disease resistance and the prevalence of internal and external defects.

Tests & Trials: The comparative trial for 'CRPTQ Joany' was conducted during the 2023 growing season in Pointe-aux-Outardes, Quebec. Plots were 14 metres by 19 metres totalling 266 squared metres and consisted of 60 plants per variety. Plants were grown in 4 replications with a row length of 5 metres, a row spacing of 1 metre and a plant interspacing of 0.3 metres.
