Variety Description

Variety used for comparison: 'Yellow Yograceland' (Graceland Yellow)

Summary: The margins of the lowest lateral sinus of the leaf are parallel for 'CIDZ0005' while the margins of 'Yellow Yograceland' are diverging. The leaf margin of 'CIDZ0005' has many indentations whereas the leaf margin of 'Yellow Yograceland' has a moderate number of indentations. The flower head of 'CIDZ0005' is smaller in diameter with a greater number of ray florets than the flower head of 'Yellow Yograceland'. The ray floret length to width ratio is high for 'CIDZ0005' while it is medium for 'Yellow Yograceland'. The inner side of the ray floret of 'CIDZ0005' is yellow whereas it is lighter yellow with dark yellow streaks for 'Yellow Yograceland'. In comparison to the colour of the inner side of the ray floret, the colour of the outer side of the ray floret is similar for 'CIDZ0005' while it is markedly different for 'Yellow Yograceland'.

Origin & Breeding History: 'CIDZ0005' originated from a controlled cross-pollination conducted in February 2006, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-A7630' as the female parent, and a proprietary line designated 'YB-B0094' as the male parent. The resultant seed was sown in a greenhouse in July 2006. 'CIDZ0005' was selected as a single plant from the progeny in November 2006 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 'CIDZ0005' 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. 50 unrooted cuttings were stuck into 15 cm pots on August 18, 2012. There were 5 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 15, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
