Origin & Breeding History: 'Stikine' originated from a cross conducted in 2004 in Courtenay, British Columbia at McGinnis Berry Corps Limited. The cross was made between the varieties 'Zusha' and 'Titania'. The new variety was selected based on resistance to rust, resistance to mildew, yield, flavour profile, frost tolerance and suitability for hand harvesting.

Tests & Trials: The comparative trial of 'Stikine' was conducted in Saanichton, British Columbia in 2015. The trial consisted of six plants per variety, planted in one row with approximately 60 cm between plants. Measured characteristics were based on 8 measurements per variety, with the exception of plant height and width where only 4 measurements were taken.
