Origin & Breeding History: 'AAC Talbot' (experimental designations 'OX-174 B', 'SN10-0003-CE-10' and 'C4M17240 conv') was developed by the Agriculture & Agri-Food Canada Harrow Research and Development Centre in Harrow, Ontario, in collaboration with La Coop fédérée in Montreal, Quebec. In 2003, the initial cross was conducted between AC756 and IA2025 followed by a subsequent cross with RCAT0601SCN made in 2010 at the Harrow Research and Development Centre. The F1 and F2 plants were grown in the greenhouse and in the field, respectively, at Harrow in 2010 and advanced using the pedigree selection method. Beginning in 2013, the F7 generation was tested as 'C4M17240 conv' by La Coop fédérée at multiple locations and years for yield, maturity, protein and oil content until 2017. In the winter of 2017 and 2018, breeder seed of 'AAC Talbot' were produced in Chile.
Tests & Trials: The comparative trials for 'AAC Talbot' were conducted in 2019 and 2021 at the Agriculture & Agri-Food Canada Harrow Research and Development Centre in Harrow, Ontario. The trials consisted of five replicates per variety with 2 rows per replication. Plots were approximately 1.2 by 5 metres and were arranged in a RCB design. For each variety, the plant height was based on 20 measurements. Mean differences were significant at the 5% probably level based on LSD values.
