Origin & Breeding History: 'AAC Carver' (experimental designation MP1920) is the result of the cross 'CDC715S-4' / 'P98089063' made in the winter of 2003 in the greenhouse at the Agriculture and Agri-Food Canada Research Station in Morden, Manitoba. The breeding method was pedigree selection in combination with single seed descent. In 2009, one line, P0405-12 was selected for its high yield potential, good resistance to lodging and seed quality. In 2010, it was multiplied and purified in a seed increase strip planted in the field in Lacombe, Alberta. It was evaluated as MP1920 at various locations throughout western Canada during the 2011 and 2012 growing seasons in the Western Canada Field Pea Cooperative Registration Test B.
Tests & Trials: Tests and trials were conducted during the 2014 and 2015 growing seasons in Lacombe, Alberta. Plots were arranged in a RCB design with 4 replicates. The plot size was 5 metres by 1 metre with a 20 cm row spacing. The seeding rate was 85 germinating seeds per square metre. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
