Origin & Breeding History: ‘NS7627MC' is a restorer inbred line developed by Pioneer Hi-Bred International, Inc. using a pedigree method of plant breeding. The variety originated from a complex cross between four proprietary inbred lines initiated in 2007 in Georgetown, Ontario, Canada. The F1 progeny was crossed with another proprietary inbred line in 2008 and a final cross of the resulting F1 progeny was conducted with another proprietary line in 2009. Filial lines were evaluated in nurseries in Ontario in 2009 and 2010. In 2011, one F6 line designated as ‘NS7627MC' was selected based on pod density, branching, pod number and size, lodging resistance, time of flowering, time of maturity and seed quality such as oil, protein and glucosinolate content. Breeder seed was established at the F6 generation in 2017.

Tests & Trials: The comparative trials for ‘NS7627MC' 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 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.
