Variety Description

Variety used for comparison: 'Yowinnipeg' (Winnipeg)

Summary: The plants of 'CIDZ0002' are taller and have longer ray florets compared to the plants of 'Yowinnipeg'. Just before opening, the colour of the outer side of the flower bud is dark purple red for 'CIDZ0002' while it is light blue violet with violet tones for 'Yowinnipeg'. The curvature along the longitudinal axis of a ray floret from the inner row is strongly incurved for 'CIDZ0002' while the ray floret of 'Yowinnipeg' is weakly incurved. The colour of the inner side of the ray floret is dark brown to dark purple red for 'CIDZ0002' while it is blue pink with lighter blue pink margins for 'Yowinnipeg'.


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

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

FLOWER BUD: outer side is dark purple red (RHS N186D) just before opening
FLOWER HEAD: double, daisy type, sparse to medium density of outer ray florets, medium to dense inner ray florets
RAY FLORET: two types, predominant type is quilled, secondary type is spatulate, very long corolla tube, profile of tube is flattened, longitudinal axis is straight, longitudinal axis of ray floret from inner row is strongly incurved along distal quarter, very high length to width ratio, dentate tip, inner side is dark brown to dark purple red (RHS N186C-D), colour of outer side is markedly different from colour of inner side, outer side is violet (RHS 76C-D) with darker violet (RHS 75A) apex, in comparison to ray floret from inner row the colour of inner and outer sides is markedly different, outer side of ray floret from inner row is black (closest to RHS N186A)
DISC: small diameter relative to head diameter, profile in cross-section is flat, green with no dark spot at centre before anther dehiscence, light yellow (RHS 13A) at anther dehiscence

Origin & Breeding History: 'CIDZ0002' 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-6132' 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 2000. 'CIDZ0002' was selected as a single plant from the progeny in November 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 'CIDZ0002' 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 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.
