Origin & Breeding History: 'Silte Pinka' originated from a cross conducted by the breeder J. Hanneke Jonkers, an employee of Goldsmith Seeds Europe, The Netherlands, as part of a planned pedigree breeding program in 2003. The cross was between the female parent 'IDY-14-9' and the male parent 'IDY-29-2' both unpatented proprietary lines. The resultant seed was sown in 2003. In the same year a single plant was selected by the breeder based on branching, plant growh habit, size of double flowers and time of flowering.

Tests & Trials: Trials for 'Silte Pinka' were conducted in a polyhouse during the summer of 2008 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 25, 2008. Observations and measurements were taken from 10 plants of each variety on June 23, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
