Origin & Breeding History: ‘AAC Hagen' (experimental designation P1222-2923) originated from a cross conducted between the varieties ‘Cooper' and ‘AAC Royce' at the Agriculture and Agri-Food Canada Lacombe Research and Development Centre in Lacombe, Alberta in 2012. The variety was developed using a pedigree selection method of breeding in combination with single seed descent. The variety was advanced to the F7 generation based on maturity, lodging resistance, yield and disease resistance. One F7 line, designated as P1222-2923, was assessed for yield in multiple locations in Western Canada in 2019 and entered in the Western Canada Field Pea Cooperative Registration Test from 2021 to 2023. Breeder seed was established from the F12 generation in 2024.
Tests & Trials: The comparative trials for ‘AAC Hagen' were conducted at the Agriculture and Agri-Food Canada Lacombe Research and Development Centre in Lacombe, Alberta during the 2024 and 2025 growing seasons. The trial consisted of 4 replicates per variety arranged in a RCB design. Each plot consisted of 4 rows, each row measuring 5 metres with 23 cm inter-row spacing. The planting density of 85 seeds per square metre resulted in approximately 1550 plants per variety per year. The measured characteristics were based on 20 measurements per year, except for seed weight which was based on 4 measurements per variety, per year. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
