Origin & Breeding History: 'AAC Beyond' (experimental designation P0938-4055) originated from the cross between 'Earlystar' and 'CDC1897-3' conducted in the winter of 2008-2009 at the Agriculture and Agri-Food Canada Lacombe Research and Development Centre in Lacombe, Alberta. The breeding method used was pedigree selection in combination with single seed descent for generation advancement. In 2014, an F6 line designated P0938-4055 was selected based on maturity, pod canopy and lodging resistance and further evaluated in a replicated preliminary yield test in Lacombe, Alberta in 2015. In 2016 P0938-4055 was tested in multiple locations in Western Canada, selected as a candidate for registration trials and in 2017 increased and purified in 2 x 15 metre strips in Lacombe, Alberta. 'AAC Beyond' was entered into the 2018-2019 Western Canada Field Pea Cooperative Registration Test-B and further tested in multiple locations in Western Canada.
Tests & Trials: The comparative tests and trials for 'AAC Beyond' were conducted at the Lacombe Research and Development Centre, Agriculture and Agri-Food Canada, Lacombe, Alberta, in 2020 and 2021. The trials consisted of 4 replicates in a RCB design. Each replicate consisted of 4 rows spaced 25 cm apart, with a row length of 5 metres and a planting density of 85 viable seeds per square metre. The measured characteristics were based on 20 measurements per variety per year except 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.
