SEED: medium sized, spherical flattened, weak glaucosity, yellow ground colour of testa, opaque testa
HILUM: imperfect yellow, funicle same colour as testa
Origin & Breeding History: ‘OAC Kamran' (experimental designation ‘SeCan 17-16C-SCN') was developed at the University of Guelph in Guelph, Ontario using a single seed descent breeding method. The variety originated from a cross between the parent ‘S23-T5' and parent ‘DH530' conducted in 2012. The variety was advanced from the F1 to the F4 generation where a single plant was selected based on maturity and agronomic traits in 2013. The variety was designated ‘SeCan 17-16C-SCN' and tested in multiple trials from 2017 to 2019 in Ontario and Quebec.
Tests & Trials: The comparative trials of ‘OAC Kamran' were conducted in St. Thomas, Ontario during the 2022 and 2023 growing seasons. The trial included 3 replicates per variety arranged in an RCB design. Each plot consisted of a 9.14 meter row with approximately 300 plants per variety per year. 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.
