Origin & Breeding History: 'PR6CN666' is a restorer line in the process of F1 hybrid production. It was derived by crossing an inbred line containing the Rf3 gene in homozygous state to a donor line, which was then crossed to a recurring parent in a backcrossing scheme. The initial cross was made at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2012. 'PR6CN666' was selected in 2016 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, improved resistance to seed pod shattering, oil content, fatty acid profile, glucosinolate content and combining ability.
Tests & Trials: The comparative trials for 'PR6CN666' were conducted during the 2016 and 2017 growing seasons in Saskatoon, Saskatchewan. They 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.
