Origin & Breeding History: 'CIDZ0017' originated from a controlled cross-pollination conducted in February 2004, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved the proprietary line designated 'YB-A7754' as the female parent, and the proprietary line designated 'YB-A7224' as the male parent. The resultant seed was sown in a greenhouse in July 2004. 'CIDZ0017' was selected as a single plant from the progeny in November 2004 by the breeder, Wendy R. Bergman, in Alva, Florida, USA, based on its flower colour, plant growth habit, and production characteristics.

Tests & Trials: The trial for 'CIDZ0017' was conducted in the fall of 2012 at Meyers Fruit Farm in Niagara on the Lake, Ontario. Flowering trials were conducted under greenhouse conditions similar to those used in commercial Chrysanthemum production. 60 unrooted cuttings were stuck into 15 cm pots on August 18, 2012. There were 3 cuttings per pot and the pots were spaced 30 cm apart. The plants were pinched once prior to short day treatment. Observations and measurements were taken from 10 plants or parts of plants, of the candidate and reference varieties on November 13, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
