Description:

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

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

FLOWER BUD: just before opening outer side is brown purple (RHS 184B-C) with tones of light yellow brown (RHS 160B)
FLOWER HEAD: double, low to medium height in non-disbudded plants, medium density of ray florets
RAY FLORET: two types, predominant type is ligulate, secondary type is incurved, very short corolla tube, flat in cross-section at widest point, no rolling of margins, longitudinal axis is straight, petaloid staminodes present, medium to high length to width ratio, emarginate and mamillate tip, inner side is dark purple red (darker than RHS 46A), colour of outer side is markedly different from colour of inner side, outer side is light yellow brown (RHS 160C) and light yellow (RHS 5D) with dark pink red (RHS N34C, 48A) overcolour, in comparison to ray floret from inner row the colour of inner and outer sides is similar

Origin & Breeding History: 'CIDZ0032' originated from a controlled cross-pollination conducted in January 1998, in Gilroy, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-6351' as the female parent, and a proprietary line designated 'YB-6606' as the male parent. The resultant seed was sown in a greenhouse in July 1998. 'CIDZ0032' was selected as a single plant from the progeny in December 1998 by the breeder, Wendy R. Bergman, based on its flower colour, and plant growth habit.

Tests & Trials: The trial for 'CIDZ0032' 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.
