Origin & Breeding History: 'PR3CN574' is a restorer line in the process of F1 hybrid production. It was derived as a doubled haploid line containing the Rf3 gene construct in homozygous state. The cross was made in Canada in 2009 with the doubled haploid line being extracted in 2010. 'PR3CN574' was selected in 2012 on the basis of fertility restoration of numerous male sterile lines and expression of tolerance to glufosinate-ammonium herbicide. Other selection parameters included height, vigour, maturity, blackleg resistance, clubroot tolerance, oil content, fatty acid profile, glucosinolate content and combining ability.

Tests & Trials: The comparative trials conducted during the summers of 2013 and 2014 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.
