Origin & Breeding History: 'Cal Depyel' was developed by the breeder, an employee of Goldsmith Seeds, California, U.S.A., as part of a planned pedigree breeding program. The new variety originated from the cross made in July 2002 between the female parent '471-1', a proprietary seedling with deep yellow coloured flowers, and the male parent '465-1', a proprietary seedling with deep yellow coloured flowers. The resultant seed was sown in January 2003 and in April 2003 a single plant was selected by the breeder based on flower colour, form and plant habit.

Tests & Trials: The tests and trials for 'Cal Depyel' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 20 plants of each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 25 cm baskets on April 20, 2006. Each basket contained 3 cuttings with a total of 7 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 10, 2006. All colour measurements were made using the RHS Colour Chart 2001.
