Origin & Breeding History: 'BIDZ0001' was bred and developed as part of a controlled breeding program by the breeder, Theodore C.M. van Kleinwee, an employee of Syngenta Seeds B.V. in Enkhuizen, Netherlands. It originated from an open pollinated cross conducted in June of 2006 between the female parent, a proprietary line designated 'FO158-1' with yellow flowers and an unknown male parent. The resultant seed was collected and sown in a greenhouse in March 2007 and in May, a single plant was selected based on its flower colour, plant growth habit, and production characteristics.
Tests & Trials: Trials for 'BIDZ0001' were conducted in a polyhouse during the spring of 2012 at BioFlora Inc., in St. Thomas, Ontario. There were 20 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 26, 2012. Observations and measurements were taken from 10 plants of the candidate variety on June 7, 2012 and on June 14, 2012 for the reference variety. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) colour Chart.
