Summary: The cotyledon of 'PB8CN252' is wider and longer than that of 'PPS01-140 B-Line' and wider than that of 'PB1CN231'. The leaf of 'PB8CN252' has a few lobes whereas the leaf of 'PPS01-140 B-Line' and '5440' have a medium number of lobes. 'PB8CN252' has a shorter petiole than that of 'PPS01-140 B-Line' and '5440'. 'PB8CN252' flowers later than 'PB1CN231'. 'PB8CN252' has a shorter silique than that of 'PPS01-140 B-Line'. 'PB8CN252' matures later than 'PPS01-140 B-Line'. The seed coat of 'PB8CN252' is black whereas it is brown for 'PB1CN231'.

DISEASE REACTION: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and Clubroot (Plasmodiophora brassicae)
Origin & Breeding History: 'PB8CN252' is the male fertile maintainer line of 'PA8CN152'. It is a non-transgenic selected line which was derived by crossing an inbred line to a donor line, which was then crossed to a recurring parent in a backcrossing scheme. The initial cross was made at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2012. 'PB8CN252' was selected in 2017 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.
Tests & Trials: The comparative trials for 'PB8CN252' were conducted during the 2018 and 2019 growing seasons in Saskatoon, Saskatchewan. They were set up in a RCB Design with 3 replications per variety. Each year, the plots consisted of 3 rows that were 6 metres in length with a spacing of 25 cm between rows and 50 cm between plots. The planting density resulted in a total of approximately 1300 plants per variety. The measured characteristics were based on 30 measurements of the cotyledon, leaf, flower and plant height and 60 measurements of the silique. The means were based on a two year average. Mean differences were significant at the 2% probability level based on LSD values.
