Variety Description
Varieties used for comparison: 'OAC Lakeview' and 'OAC Durham'
Summary: When cotyledons are completely unfolded, anthocyanin accumulation in the hypocotyl is present for ‘OAC Shine' whereas it is absent for ‘OAC Durham. When 95% of the pods are ripe, the plants of ‘OAC Shine' are taller than those of ‘OAC Durham'. When 50% of the plants are flowering, the terminal and lateral leaves of ‘OAC Shine' are longer than those of ‘OAC Lakeview'. The flower of ‘OAC Shine' is violet whereas the flower of ‘OAC Durham' is white. When 95% of the pods are ripe, the pod of ‘OAC Shine' is longer than that of ‘OAC Lakeview'.
Description:
HYPOCOTYL: medium intensity of anthocyanin colouration
PLANT: indeterminate growth type, grey pubescence on middle third of main stem, begins flowering mid-season, matures mid-season
LEAF: medium green upper side
TERMINAL LEAFLET: ovoid, medium size
LATERAL LEAFLET: pointed ovate, medium size
FLOWER: violet
POD: light to medium brown
SEED: medium sized, spherical flattened, weak glaucosity, yellow ground colour of testa, opaque testa
HILUM: yellow, funicle same colour as testa
Origin & Breeding History: ‘OAC Shine' (experimental designation ‘SeCan 16-13C') 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 variety ‘Colby' 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 16-13C' and tested in multiple trials from 2016 to 2019 in Ontario.
Tests & Trials: The comparative trials of ‘OAC Shine' were conducted in St. Thomas, Ontario during the 2021 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, 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.
