Origin & Breeding History: ‘PB1CN282' is a male fertile maintainer line of ‘PA1CN182'. It is a non-transgenic selected line which was derived by crossing an inbred line containing the Ms8 gene to a donor line, which was then crossed to a recurring parent in a backcrossing scheme. The initial cross was conducted in Gent, Belgium in 2017. ‘PB1CN282' was selected in 2018 based on its expression of resistance to glyphosate herbicide, per se performance, height, vigour, maturity, blackleg resistance, clubroot resistance, seed pod shattering resistance, oil content, fatty acid profile and glucosinolate content. Breeder seed production commenced in Gent, Belgium in 2019.

Tests & Trials: The comparative trials for ‘PB1CN282' were conducted during the 2022 and 2023 growing seasons in Saskatoon, Saskatchewan. Trials were arranged in a RCB design with 3 replications per variety. The plots consisted of 3 rows that were 6 metres in length with spacing of 25 cm between rows and 50 cm between plots. The planting density resulted in a total of approximately 1300 plants per variety per year. The measured characteristics were based on 30 measurements except for silique characteristics which were based on 60 measurements. The means were based on a two-year average. Mean differences were significant at the 2% probability level based on LSD values.
