Origin & Breeding History: 'PR9CN411' is a restorer inbred line used in F1 hybrid production, that contains the Rf3 gene construct in homozygous state. 'PR9CN411' is a doubled haploid line that was produced in Canada in 2007. It was selected in 2008 on the basis of fertility restoration of numerous male sterile lines and expression of tolerance to glufosinate ammonium herbicide. Other selection criteria included height, vigour, maturity, blackleg resistance, oil content, fatty acid profile, glucosinolate content and combining ability.

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.
