Origin & Breeding History: 'PR2CN524' 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 2007 with the doubled haploid line being extracted in 2009. 'PR2CN524' was selected in 2011 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, oil content, fatty acid profile, glucosinolate content and combining ability.
Tests & Trials: Trials conducted in the summers of 2012 and 2013 in Saskatoon, Saskatchewan were set up in a RCB Design with 3 replications per variety. Plots each year consisted of 3 rows 6 metres in length with a spacing of 25 cm between rows and 50 cm between plots. There were 30 measurements of the cotyledon, leaf, flower and plant height characteristics and 60 measurements of the silique characteristics. Means are based on a two year average. Differences are significant at the 2% probability level based on LSD values.
