Origin & Breeding History: 'PB9CN201' is a male fertile maintainer line of 'PA9CN101'. 'PB9CN201' is a doubled haploid line that was produced in Canada in 2003. It was selected in 2006 and 2007 on the basis of height, vigour, maturity, blackleg resistance, oil content, fatty acid profile and glucosinolate content.

Tests & Trials: Trials were conducted in Saskatoon, Saskatchewan during the summers of 2009 and 2010. In 2009, the trial was set up with 3 replicates arranged in a RCB design. In 2010, the trial setup was 3 replicates arranged in Lattice design. Each year the plots consisted of 3 rows with a row length of 6 metres and a row spacing of 50 cm.
