Origin & Breeding History: 'CDC SB-3' (experimental designation IBC697) was developed from the cross 'CDC SB-2' /// 'CDC SB-2' // 'CDC SB-2' / 'IBC145' carried out in 2010 at the Crop Development Centre at the University of Saskatchewan, Saskatoon, Saskatchewan. Selections were made in the F1 to F4 generations, where 9 sub-lines were used to establish the breeder seed. Throughout the generations, selections were based on yield, seed weight, seed size (including diameter and plumpness), seed coat colour, cotyledon colour, days to flowering, days to maturity, resistance to lodging, plant height, herbicide tolerance and disease resistance. 'CDC SB-3' was entered in and evaluated as IBC697 in the Pulse and Special Crops Cooperative Registration Tests in 2012 and 2013.

Tests & Trials: The tests and trials for 'CDC SB-3' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the summers of 2014 and 2015. 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 95 seeds per square metre. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
