Origin & Breeding History: 'PA8CN157' is a male sterile line which contains the Ms8 gene construct in the heterozygous state. It was derived by crossing an inbred line containing the Ms8 gene to a donor line, which was then used as a recurring parent in a backcrossing scheme. The initial cross and subsequent backcross were conducted in Gent, Belgium in 2016 and 2017, respectively. 'PA8CN157' was selected in 2017 on the basis of male sterility stability, its expression of tolerance to glufosinate-ammonium herbicide and to glyphosate herbicide and good combining ability with numerous restorer lines. Other selection parameters included vigour, maturity, blackleg resistance, clubroot tolerance, seed pod shattering resistance, oil content, fatty acid profile and glucosinolate content. Breeder seed production commenced in Saskatoon, Saskatchewan, Canada in 2017.
Tests & Trials: The comparative trials for 'PA8CN157' 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.
