Origin & Breeding History: 'Bomy Dabule' originated from a cross between the female parent 'Saphira' and the male parent '204-4'. The new variety was bred and developed by the breeder Jason Jandrew in August 2006, in Gilroy, California, USA. The resultant seed from the cross was sown in a greenhouse in January 2007. In May 2007, a single plant from the progeny was selected by the breeder based on flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Bomy Dabule' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on May 19, 2010. Observations and measurements were taken from 10 plants of each variety on July 9, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
