Variety Description

Varieties used for comparison: 'PPS02-364', 'PPS04-205' and '5440'

Summary: The cotyledon of 'PR9CN767' is shorter than the cotyledon of '5440' and narrower than those of the reference varieties. 'PR9CN767' has a longer leaf and petiole than 'PPS02-364'. The plants of 'PR9CN767' flower later than the plants of the reference varieties. The petal of 'PR9CN767' is longer than that of 'PPS04-205'. The silique of 'PR9CN767' is shorter than that of 'PPS02-364'. At maturity, the plants of 'PR9CN767' are taller than the plants of 'PPS04-205'.

CHEMICAL REACTION: resistant to glufosinate ammonium herbicides

DISEASE REACTIONS: resistant to Blackleg (Leptosphaeria maculans asexual stage: Phoma lingam) and tolerant to Clubroot (Plasmodiophora brassicae)

Origin & Breeding History: 'PR9CN767' is a restorer line in the process of F1 hybrid production. It was derived as a double haploid line containing the Rf3 gene in a homozygous state. The cross was made at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2016 and the subsequent double haploid line extraction was made at BASF Canada Inc. in Saskatoon, Saskatchewan, Canada in 2017. 'PR9CN767' was selected in 2018 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, seed pod shatter resistance, oil content, fatty acid profile, glucosinolate content and combining ability. Breeder seed production commenced in Saskatoon, Saskatchewan, Canada in 2019.

Tests & Trials: The comparative trials for 'PR9CN767' were conducted during the 2019 and 2021 growing seasons in Saskatoon, Saskatchewan. Trials were arranged in a RCB design with 3 replications per variety. The plots consisted of 3 rows that were 6 metres in length with spacing of 25 cm between rows and 50 cm between plots. The planting density resulted in a total of approximately 1300 plants per variety per year. The measured characteristics were based on 30 measurements except for the silique characteristics which were based on 60 measurements. The means were based on a two year average. Mean differences were significant at the 2% probability level based on LSD values.
