Origin & Breeding History: ‘CDC Berilo' (experimental designation 9820-1-H2-3) originated from the cross between ‘8416S' and ‘7888M-1' conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2017 A single plant selection was made from the F2 generation with further selections made at the F3 generation. ‘CDC Berilo' was selected in 2020 at the F4 generation based on yield, seed weight, seed size, seed colour, cotyledon colour, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Breeder seed was established using 20 F9 sub-lines in 2025.

Tests & Trials: The comparative trials for ‘CDC Berilo' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the 2024 and 2025 growing seasons. The trials consisted of 3 replications per variety arranged in a RCB design. Each replicate consisted of 3 rows spaced 30 cm apart, with a row length of 3.66 metres and a planting density of 94 seeds per square metre. Measured characteristics were based on 30 measurements per variety per year, except for seed weight which was on 12 measurements per variety per year. Mean differences were significant at the 5% probability level based on a Student's t-test. The herbicide tolerance was evaluated by spraying plants at the 6 to 8 node stage with 0, 1, 2 and 4 times the recommended application rates for two separate imidazolinone herbicide treatment types. The first herbicide treatment was Solo ADV (at rates of 20, 40, and 80 grams active ingredient per hectare) and the second herbicide treatment was a combination of Odyssey (at rates of 30, 60, and 120 grams active ingredient per hectare) with Merge (0.5%, 1.0%, and 2.0% volume by volume), respectively. The Canadian Weed Science Society 0-100 Rating Scale for Herbicide Efficacy and Crop Phytotoxicity was used to assess the plant injury. The plant injury ratings for herbicide tolerance traits were assessed visually at 16 and 23 days after treatment with plant chlorosis, stunting, and overall biomass being compared against untreated control plants.
