Variety Description

Variety used for comparison: 'Yoharvard' (Harvard)

Summary: The plants of 'CIDZ0007' have darker green leaves and longer ray florets compared to the plants of 'Yoharvard'. The depth of the lowest lateral sinus of the leaf is medium to deep for 'CIDZ0007' while it is shallow to medium depth for 'Yoharvard'. The margins of the lowest lateral sinus of the leaf are mostly diverging for 'CIDZ0007' while they are mostly touching for 'Yoharvard'. The leaf margin of 'CIDZ0007' has a moderate number of medium depth incisions whereas the leaf margin of 'Yoharvard' has many, deep incisions. The profile at the widest point of the ray floret in cross-section is weakly convex for 'CIDZ0007' while it is moderately concave for 'Yoharvard'. The margin of the ray floret of 'CIDZ0007' is moderately revolute along the distal half while for 'Yoharvard', the margin of the ray floret is weakly involute along the basal quarter. The colour of the outer side of the ray floret of 'CIDZ0007' is brown purple with lighter tones whereas the ray floret of 'Yoharvard' is light yellow brown with strong, brown purple, mottled overcolour.

Origin & Breeding History: 'CIDZ0007' originated from a controlled cross-pollination conducted in June 2006, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-6483' as the female parent, and a proprietary line designated 'YB-A8021' as the male parent. The resultant seed was sown in a greenhouse in October 2006. 'CIDZ0007' was selected as a single plant from the progeny in March 2007 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 'CIDZ0007' 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. Plants of the candidate variety were disbudded. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate variety, and 9 plants, or parts of plants, of the reference variety on November 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
