Origin & Breeding History: ‘4PSBG05R' is a restorer line developed by Pioneer Hi-Bred International, Inc. using a pedigree method of plant breeding. The variety originated from a cross between two proprietary inbred lines conducted in 2013 in Carman, Manitoba, Canada. The F5 and F6 lines were evaluated in a Manitoba field nursery in 2014 and 2015. In 2017, one F6 line designated as ‘4PSBG05R' was selected based on plant vigour, time of flowering and pod development, glucosinolate levels, saturated fats, and oil content. Breeder seed production commenced in 2021.

Tests & Trials: The comparative trials for ‘4PSBG05R' were conducted during the 2022 and 2023 growing seasons in Saskatoon, Saskatchewan. The trial included 3 replicates. The candidate and reference variety were sown side by side in the first replicate whereas varieties in the second and third replicate were completely randomized. The plots consisted of 2 rows that were 3 metres in length with spacing of 50 cm between rows. The planting density of 26 seeds per metre resulted in a total of 468 plants per variety per year. The measured characteristics were based on 30 measurements per variety per year except for silique characteristics which were based on 60 measurements per variety per year. Mean differences were significant at the 2% probability level based on LSD values.
