Origin & Breeding History: 'AAC Brown 120' (experimental designation B1630DH182) is a non-restorer parent in the process of F1 hybrid production. It was derived as a double haploid line created from the microspore culture of a hybrid that originated from a cross between the double haploid line 'B474DH100' and double haploid line 'O60DH151'. The final cross was conducted during 2013 at the Agriculture and Agri-Food Canada Research and Development Centre in Saskatoon, Saskatchewan, Canada. During the growing season of 2014, 'AAC Brown 120' was selected from the double haploid population based on agronomic evaluation for early vigour, maturity and quality traits (protein, oil and chlorophyll contents) in a two replicate nursery in Saskatoon.
Tests & Trials: The comparative trials for 'AAC Brown 120' were conducted during the 2022 and 2023 growing seasons at the Ag-Quest Research Farm in Saskatoon, Saskatchewan. Plots were arranged in a RCB design with 4 replicates per variety per year. Each 5 metre square plot consisted of six rows 5 metres in length with a row spacing of 20 centimetres. The planting density was 100 seeds per row. Measured characteristics were based on 30 measurements per variety except for silique characteristics which were based on 60 measurements. Mean differences were significant at the 5% confidence probability level based on a paired Student`s t-test.
