Variety Description

Variety used for comparison: 'DH530'

Summary: When the cotyledons are completely unfolded, the hypocotyl of 'OAC Malory' has a medium intensity of anthocyanin colouration while that of 'DH530' has a weak intensity of anthocyanin colouration. When 50% of the plants are flowering, the hairs on the middle third of the stem of 'OAC Malory' are grey while those of 'DH530' are tawny. The leaf of 'OAC Malory' has a medium degree of blistering while that of 'DH530' has weak blistering. When 95% of the pods are ripe, the pod of 'OAC Malory' is light to medium brown while that of 'DH530' is dark brown. The pod of 'OAC Malory' is longer than that of 'DH530'. At maturity, the hilum of 'OAC Malory' is yellow while that of 'DH530' is imperfect yellow. The plants of 'OAC Malory' mature earlier than those of 'DH530'.

Origin & Breeding History: 'OAC Malory' (experimental designation SeCan 15-29C-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 varieties 'Colby' and 'DH410' 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 2011. The variety was designated SeCan 15-29C-SCN at the F8 generation in 2015 with breeder seed being established at the F4:10 generation in 2017.

Tests & Trials: The comparative trials of 'OAC Malory' 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. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
