Origin & Breeding History: 'CDC Sunset' (experimental designation 2510-2) originated from a cross conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan. The initial cross occurred in 2010 between 'CDC Cory' and 'GPE094'. The resulting F1 was then crossed to 'CDC Consul'. A single plant selection was made at the F2 generation. The variety was advanced with subsequent selections made through the F3 to F8 generations based on yield, seed weight, seed size, seed coat colour, days to flower, days to maturity, plant height and disease resistance. In 2020, 32 F9 sub-lines were used to establish breeder seed.

Tests & Trials: The comparative trials for 'CDC Sunset' were conducted by the Crop Development Centre, University of Saskatchewan, at Elrose, Saskatchewan in 2021 and 2022. The trials were arranged in 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 40 seeds per square metre. Measured characteristics were based on 20 measurements per variety per year except for seed weight which was based on 8 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based LSD values. Herbicide tolerances were supported by data provided by the University of Saskatchewan using the methodology as published in Tar`an B. et al. 2014 Theor. Appl. Genet. 127: 1583-1591.
