Origin & Breeding History: 'PB4CN280' is the male fertile maintainer line of 'PA4CN180'. It is a non-transgenic double haploid line which was extracted in 2010 from the F1 generation of a cross produced at Bayer CropScience in Saskatoon, Canada in 2009. 'PB4CN280' was selected in 2013 and 2014 on the basis of per se performance of height, vigour, maturity, blackleg resistance, oil content, fatty acid profile and glucosinolate content.
Tests & Trials: The comparative trials conducted during the summers of 2014 and 2015 in Saskatoon, Saskatchewan 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 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.
