Summary: The cotyledon of 'PB7CN238' is wider than that of 'PB1CN231' and 'PPS01-140 B-Line' whereas it is narrower and shorter than that of '5440'. The leaf of 'PB7CN238' has many to very many lobes whereas 'PB1CN231' has a few lobes and those of 'PPS01-140 B-Line' and '5440' have a medium number of lobes. The leaf of 'PB7CN238' is narrower than that of '5440'. 'PB7CN238' has a shorter petiole than that of 'PPS01-140 B-Line' and '5440'. 'PB7CN238' flowers earlier than '5440'. The petal of 'PB7CN238' is wider than that of 'PB1CN231'. The silique attitude of 'PB7CN238' is horizontal whereas the silique attitude is erect for 'PB1CN231'. The silique of 'PB7CN238' is longer than the reference varieties. The silique of 'PB7CN238' has a longer beak than that of 'PPS01-140 B-Line'. 'PB7CN238' matures earlier than 'PB1CN231' and '5440'. The seed coat of 'PB7CN238' is black whereas it is brown for 'PB1CN231'.

Origin & Breeding History: 'PB7CN238' is the male fertile maintainer line of 'PA7CN138'. It is a non-transgenic double haploid line, which was extracted in 2011, from a cross conducted at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2010. 'PB7CN238' was selected in 2017 on the basis of per se performance, height, vigour, maturity, blackleg resistance, clubroot resistance, seed pod shattering resistance, oil content, fatty acid profile and glucosinolate content.
Tests & Trials: The comparative trials for 'PB7CN238' 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.
