Variety Description

Variety used for comparison: 'Yoolympia' (Olympia)

Summary: The leaf of 'CIDZ0008' is shorter than the leaf of 'Yoolympia'. 'CIDZ0008' has a shorter petiole relative to the leaf length than 'Yoolympia'. The flower head of 'CIDZ0008' is smaller in diameter with narrower ray florets than the flower head of 'Yoolympia'. The length to width ratio of the ray floret of 'CIDZ0008' is greater than that of 'Yoolympia'.

Description:

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

PETIOLE: attitude is moderately upwards, short 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 and truncate, absent or weak glossiness on upper side, medium green on upper side, medium number of indentations of margin, medium depth of indentations of margin

FLOWER BUD: outer side is white (RHS NN155B) just before opening
FLOWER HEAD: double, medium height in non-disbudded plants, dense ray florets
RAY FLORET: two types, predominant type is spatulate, secondary type is incurved, attitude of basal part is horizontal, long corolla tube, profile of corolla tube is triangular; longitudinal axis ranges from incurving to straight, having weak to medium strength incurving along less than distal quarter; longitudinal axis of ray floret from inner row has medium strength incurving along distal half, very high length to width ratio; pointed, emarginate and mamillate tips; inner side is white (RHS NN155D), colour of outer side is similar to colour of inner side, outer side is white (RHS NN155D), colour of inner side of ray floret from inner row is similar to colour of inner side of ray floret from outer row

Origin & Breeding History: 'CIDZ0008' originated from a controlled cross-pollination conducted in June 2006, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved the proprietary line designated 'YB-A6182' as the female parent, and the proprietary line designated 'YB-A5410' as the male parent. The resultant seed was sown in a greenhouse in October 2006. 'CIDZ0008' was selected as a single plant from the progeny in March 2007 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 'CIDZ0008' 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 of the reference variety on November 13, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
