Variety Description

Variety used for comparison: 'White Yomistique' (Mistique White)

Summary: The plants of 'CIDZ0017' are taller with a shorter leaf (including petiole), and a greater number of ray florets per flower head than the plants of 'White Yomistique'. The length of the terminal lobe of the leaf relative to the leaf length is medium for 'CIDZ0017' while it is long for 'White Yomistique'. The density of the ray florets of the flower head of CIDZ0017' is medium while the density of the ray florets of 'While Yomistique' is sparse.


PLANT: fleurette type pot chrysanthemum, bushy type, upright growth habit, medium density of branching, response group 2 (6 weeks) when grown with precise day length control
STEM: green

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

FLOWER BUD: outer side is white (RHS NN155B) just before opening
FLOWER HEAD: semi-double, daisy type, low height in non-disbudded plants, three rows of ray florets, medium density of ray florets
RAY FLORET: ranging from 35 to 55 per flower head, ligulate type, attitude of basal part is moderately ascending to horizontal, smooth upper surface, short corolla tube, flat profile in cross-section at widest point, no rolling of margins, longitudinal axis is straight, medium length to width ratio, dentate and mamillate tips, inner side is white (whiter than RHS NN155D), colour of outer side is similar to colour of inner side
DISC: medium size diameter relative to flower head diameter, profile in cross-section is indented, green without dark spot at centre before anther dehiscence, medium yellow at anther dehiscence

Origin & Breeding History: 'CIDZ0017' originated from a controlled cross-pollination conducted in February 2004, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved the proprietary line designated 'YB-A7754' as the female parent, and the proprietary line designated 'YB-A7224' as the male parent. The resultant seed was sown in a greenhouse in July 2004. 'CIDZ0017' was selected as a single plant from the progeny in November 2004 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 'CIDZ0017' 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. 60 unrooted cuttings were stuck into 15 cm pots on August 18, 2012. There were 3 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 13, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
