Origin & Breeding History: 'Boreal Beauty' (experimental code 21-12-11.4) originated from a controlled cross made in 2010 at the University of Saskatchewan Horticulture Research Plots, Saskatoon, Saskatchewan. The cross was made between the variety '6-16-30' and '6-25-52' from the Maxine Thompson breeding program. 'Boreal Beauty' was selected in 2014 for its blooming time; fruit productivity, size and flavour; and its bush attributes for mechanical harvesting.

Tests & Trials: The comparative trials for 'Boreal Beauty' were planted in 2016 and conducted during the 2020 and 2021 growing seasons at the University of Saskatchewan Horticulture Plots in Saskatoon, Saskatchewan. The trial initially consisted of 7 plants per variety, but there was some loss due to deer and rabbits. The plants were grown in 30 metre rows with 1 metre spacing between plants. The distance between rows within the trial was 3.5 metres. Guard rows were taller and 6 years older than the variety trial. Observations and measurements were taken from 7 plants, or parts of 7 plants, of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
