Variety Description

Variety used for comparison: 'Yogolden Gate' (Golden Gate)

Summary: The plants of 'CIDZ0001' are larger than the plants of 'Yogolden Gate'. The plant growth habit is upright for 'CIDZ0001' while it is semi-upright for 'Yogolden Gate'. The flower head of 'CIDZ0001' has three types of ray florets; ligulate, incurved, and spatulate, whereas the flower head of 'Yogolden Gate' has only spatulate ray florets. Curvature of the longitudinal axis of the ray floret is moderately reflexing for 'CIDZ0001' while the ray floret of 'Yogolden Gate' is weakly incurving.


PLANT: pot chrysanthemum, bushy type, upright growth habit, sparse branching
STEM: green

PETIOLE: attitude is moderately upwards, medium length relative to leaf length
LEAF: medium length to width ratio, length of terminal lobe relative to leaf length is medium, lowest lateral sinus is shallow to medium depth, margins of lowest lateral sinus are diverging, predominant shape of base is obtuse, dark green on upper side, medium number of indentations of margin, medium depth of indentations of margin

FLOWER BUD: outer side is yellow (RHS 6C) just before opening
FLOWER HEAD: double, high height in non-disbudded plants, dense ray florets
RAY FLORET: more than two types, predominant type is ligulate, secondary type is incurved, tertiary type is spatulate, attitude of basal part is moderately descending, medium length corolla tube, moderately convex in cross-section at widest point, weakly revolute margins, longitudinal axis is moderately reflexed along distal quarter, longitudinal axis of ray floret from inner row is strongly incurved along distal half, high length to width ratio, mamillate tip, inner side is yellow (brighter than RHS 6A) with a darker yellow (RHS 9A) tip and veins, colour of outer side is similar to colour of inner side

Origin & Breeding History: 'CIDZ0001' originated from a controlled cross-pollination conducted in November 1999, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-6177' as the female parent, and a proprietary line designated 'YB-4206' as the male parent. The resultant seed was sown in a greenhouse in November 1999. 'CIDZ0001' was selected as a single plant from the progeny in July 2000 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 'CIDZ0001' 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 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
