Variety Description
Varieties used for comparison: 'PPS02-364', 'PPS04-205' and '5440'
Summary: The cotyledon of 'PR4CN583' is narrower and shorter than that of '5440'. The leaf and petiole of 'PR4CN583' are longer than that of 'PPS02-364'. The leaf of 'PR4CN583' is narrower than that of '5440'. 'PR4CN583' flowers later than 'PPS02-364' and '5440'. The petal of 'PR4CN583' is narrower than those of 'PPS04-205' and '5440'. The silique of 'PR4CN583' is longer than that of 'PPS04-205'. The beak of 'PR4CN583' is shorter than that of 'PPS02-364' whereas the pedicel is longer than that of 'PPS02-364'. 'PR4CN583' matures later than the reference varieties.

Origin & Breeding History: 'PR4CN583' 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 at Bayer CropScience in Saskatoon, Saskatchewan, Canada in 2011 with the doubled haploid line being extracted in 2011. 'PR4CN583' was selected in 2014 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: The comparative trials conducted during the summers of 2014 and 2015 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.
