Origin & Breeding History: ‘PR23CN894' 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 between proprietary lines was made in Saskatoon, Saskatchewan, Canada in 2019 and the subsequent double haploid line extraction was made from the resulting F1 in 2019. ‘PR23CN894' was selected in 2023 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, clubroot resistance, seed pod shattering resistance, oil content, fatty acid profile, glucosinolate content and combining ability. Breeder seed production commenced in Saskatoon, Saskatchewan, Canada in 2023.
Tests & Trials: The comparative trials for ‘PR23CN894' were conducted during the 2023 and 2024 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 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.
