Origin & Breeding History: The male asparagus hybrid 'Guelph Galaxy' (experimental number UG023) is produced by crossing a female clone and a supermale clone. The initial cross was made at the University of Guelph, Guelph, Ontario in 2006. The female parent was a plant selected from an open-pollinated asparagus variety. The supermale parent was a plant grown from seed extracted from andromonoecious berries found on a male asparagus hybrid. Selection criteria for 'Guelph Galaxy' included yield and spear quality.
Tests & Trials: The comparative trials for 'Guelph Galaxy' were conducted at the Simcoe Research Station, Simcoe, Ontario in 2021 and 2022. The trial was designed as a randomized complete block design with 3 replicates each of which contained 20 plants. Plants were spaced 30 cm apart with a distance between rows of 1.25 metres.
