Origin & Breeding History: 'CDC Sublime' (experimental designation IBC1264-1) originated from the cross between 6538 and 'CDC KR-2' with 3 subsequent backcrosses to 6538. Crosses were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan from 2013 to 2014. During the F1 to F4 generations, selections were made based on yield, seed weight, seed size, seed coat colour, cotyledon colour, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Seed from nine F4 sub-lines was bulked to establish breeder seed in 2019.

Tests & Trials: The comparative trials for 'CDC Sublime' were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2019 and 2021. The trials were conducted using a RCB design consisting of 2 replications per variety. 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 20 measurements per variety per year except for seed weight which was based on a minimum of 8 measurements per variety per year. Mean differences were significant at the 5% probability level based on LSD values.
