Tests & Trials: The comparative trials for 'MINSYWHI07' were conducted in an outdoor irrigated container trial during the spring and summer 2023 in St. Thomas, Ontario. The trial included 10 plants of the candidate and reference variety. All plants were grown in 6.4 cm liners and planted into 7.6 litre containers in summer 2021. The plants were overwintered in an un-heated polyhouse. Observations and measurements were taken from 10 plants, or 10 parts of plants on August 24, 2023. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
