Variety Description
Varieties used for comparison: 'OAC Strive' and 'OAC Evolution'
Summary: When the cotyledons are completely unfolded, the hypocotyl of 'OAC Hastings' has a medium intensity of anthocyanin colouration while that of 'OAC Strive' has a weak intensity of anthocyanin colouration. When 50% of the plants are flowering, the terminal and lateral leaves of 'OAC Hastings' are longer than those of 'OAC Evolution'. When 95% of the pods are ripe, the pod of 'OAC Hastings' is longer than the pod of 'OAC Evolution' and wider than that of 'OAC Strive'. At maturity, the seed of 'OAC Hastings' is smaller than that of 'OAC Strive'. The one hundred seed weight of 'OAC Hastings' is less than that of 'OAC Strive'. The plants of 'OAC Hastings' mature later than the plants of 'OAC Strive'.

Origin & Breeding History: 'OAC Hastings' (experimental designation SeCan 16-12C-Tof) 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 varieties 'OAC 05-30' and 'Venus' conducted in 2010. The variety was advanced from the F1 to the F4 generation where a single plant was selected based on maturity and agronomic traits in 2012. The variety was designated SeCan 16-11C-Tof at the F8 generation in 2016 with breeder seed being established at the F4:10 generation in 2017.
Tests & Trials: The comparative trials of 'OAC Hastings' were conducted in St. Thomas, Ontario during the 2020 and 2022 growing seasons. The trial included three replicates per variety in an RCB design. Each plot was a 9.14 meter row consisting of approximately 180 plants spaced 5 cm apart resulting in approximately 500 plants per variety per year. Measured characteristics were based on 20 measurements per variety per year except for seed weight which was based on a minimum of 3 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
