Origin & Breeding History: 'CDC 6964' (experimental designation 6964-6) originated from the cross between 5372-43 and IBC1126-2 conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2014. A single plant selection was made from the F2 generation with further selections made at the F3 generation based on yield, seed weight, seed size which includes diameter and plumpness, seed coat colour, cotyledon colour, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Seed from fifty F9 sub-lines was bulked to establish breeder seed in 2021.

Tests & Trials: The comparative trials for 'CDC 6964' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan in 2021 and 2022. 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.
