CIDZ0006

Chrysanthemum

Variety Description

Variety used for comparison: 'Yoeugene' (Eugene)

Summary: Just before opening, the flower bud of 'CIDZ0006' is white with yellowish white along the margins, and yellow at the base, while the flower bud of 'Yoeugene' is light yellow. The attitude of the basal part of the ray floret of 'CIDZ0006' is moderately ascending while it is horizontal for 'Yoeugene'. Upon opening, the distribution of the secondary colour on the inner side of the ray floret of 'CIDZ0006' is along the distal three quarters whereas the secondary colour is distributed throughout the ray floret of 'Yoeugene'. When fully opened, the distribution of the secondary colour on the inner side of the ray floret of 'CIDZ0006' is at the base while it is also at the base for 'Yoeugene', but as a smaller band of colour. The profile in cross-section of the disc of 'CIDZ0006' is indented and slightly domed whereas the disc of 'Yoeugene' is indented and strongly domed.

Description:

PLANT: pot chrysanthemum, bushy type, upright growth habit, medium density of branching
STEM: green

PETIOLE: attitude is moderately upwards, long 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 shallow to medium depth, margins of lowest lateral sinus are diverging and parallel, predominant shape of base is acute and obtuse, absent or weak glossiness on upper side, medium to dark green on upper side, medium to many indentations of margin, medium depth of indentations of margin

FLOWER BUD: just before opening outer side is white (RHS 155A) with yellowish white (RHS N155B) along margin and yellow (RHS 4A) at base
FLOWER HEAD: many per stem, semi-double, daisy type, medium height in non-disbudded plants, two to three rows of ray florets, medium density of ray florets
RAY FLORET: ranging from 23 to 32 per flower head, ligulate type, attitude of basal part is moderately ascending, two keels on upper surface, very short corolla tube, flat to weakly convex profile in cross-section at widest point, having both weakly revolute margins on middle half and no rolling of margins, longitudinal axis is very weakly incurved to straight along distal quarter, medium length to width ratio, pointed and mamillate tips, when newly opened main colour on inner side is light yellow (RHS 4D) with secondary colour of violet (RHS 75A) and blue pink (RHS N74D) over colour, when fully opened main colour of inner side is blue pink (RHS N74C) and violet (RHS 75A) with lighter violet (RHS 75C) undertones and with secondary colour of light yellow (RHS 4D) at base, secondary colour of inner side of newly opened ray floret is distributed as diffuse stripes and flush along distal three quarters, secondary colour of inner side of fully opened ray floret is distributed as diffuse stripes and flush at base, colour of outer side is markedly different from colour of inner side, outer side is light yellow (RHS 4D) and white (RHS N155D) with yellow to yellow green (RHS 4B-C) at base, colour of inner side of ray floret from inner row is similar to colour of inner side of ray floret from outer row
DISC: small to medium size diameter relative to flower head diameter, profile in cross-section is indented and slightly domed, green to yellowish without dark spot at centre before anther dehiscence, yellowish green at anther dehiscence

Origin & Breeding History: 'CIDZ0006' originated from a controlled cross-pollination conducted in April 2006, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved the proprietary line designated 'YB-A3383' as the female parent, and the proprietary line designated 'YB-A7784' as the male parent. The resultant seed was sown in a greenhouse in July 2006. 'CIDZ0006' 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 'CIDZ0006' 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.
