Variety Description
Varieties used for comparison: 'OAC Avatar' and 'OAC Eve'
Summary: When the cotyledons are completely unfolded, the hypocotyl of 'OAC Elevation' has a medium to strong intensity of anthocyanin colouration while anthocyanin colouration is absent on the hypoctyl of 'OAC Eve'. When 50% of the plants are flowering, the hairs on the middle third of the stem of 'OAC Elevation' are tawny while those of 'OAC Avatar' are light tawny. Leaf blistering for 'OAC Elevation' ranges between a weak to medium and medium degree while it is very weak for 'OAC Avatar'. The flower of 'OAC Elevation' is violet while that of 'OAC Eve' is white. When 95% of the pods are ripe, the pod of 'OAC Elevation' is shorter and wider than that of 'OAC Eve'. At maturity, the seed of 'OAC Elevation' is longer than that of 'OAC Avatar' and wider than that of 'OAC Eve'. The seed weight of 'OAC Elevation' is greater than that of the reference varieties. The plants of 'OAC Elevation' mature earlier than the plants of 'OAC Avatar' and later than those of 'OAC Eve'.

Origin & Breeding History: 'OAC Elevation' (experimental designation SeCan 16-11C-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 Elevation' 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.
