CHEMICAL REACTION: susceptible to glufosinate ammonium herbicides

DISEASE REACTIONS: moderately resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam); resistant to Clubroot (Plasmodiophora brassicae)

Origin & Breeding History: 'PB1CN285' is the male fertile maintainer line of 'PA1CN185'. It is a non-transgenic selected line which was derived by crossing a donor line containing the Ms8 gene to an inbred line, with the inbred line used as a recurring parent in a backcrossing scheme. The initial cross was conducted in Saskatoon, Saskatchewan, Canada in 2017. 'PB1CN285' was selected in 2019 on the basis of per se performance, vigour, maturity, blackleg resistance, clubroot resistance, seed pod shattering resistance, oil content, fatty acid profile and glucosinolate content. Breeder seed production commenced in Saskatoon, Saskatchewan, Canada in 2020.

Tests & Trials: The comparative trials for 'PB1CN285' were conducted during the 2021 and 2022 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 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.
