Variety Description

Variety used for comparison: 'Yoharvard' (Harvard)

Summary: The plants of 'CIDZ0007' have darker green leaves and longer ray florets compared to the plants of 'Yoharvard'. The depth of the lowest lateral sinus of the leaf is medium to deep for 'CIDZ0007' while it is shallow to medium depth for 'Yoharvard'. The margins of the lowest lateral sinus of the leaf are mostly diverging for 'CIDZ0007' while they are mostly touching for 'Yoharvard'. The leaf margin of 'CIDZ0007' has a moderate number of medium depth incisions whereas the leaf margin of 'Yoharvard' has many, deep incisions. The profile at the widest point of the ray floret in cross-section is weakly convex for 'CIDZ0007' while it is moderately concave for 'Yoharvard'. The margin of the ray floret of 'CIDZ0007' is moderately revolute along the distal half while for 'Yoharvard', the margin of the ray floret is weakly involute along the basal quarter. The colour of the outer side of the ray floret of 'CIDZ0007' is brown purple with lighter tones whereas the ray floret of 'Yoharvard' is light yellow brown with strong, brown purple, mottled overcolour.

Description:

PLANT: pot chrysanthemum, bushy type, upright growth habit, sparse 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 to deep, margins of lowest lateral sinus are mostly diverging, predominant shape of base is truncate, weak to strong glossiness of upper side, 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 187C) just before opening
FLOWER HEAD: double, medium height in disbudded plants, medium to dense ray florets, ray florets from inner rows are dense
RAY FLORET: two types, predominant type is ligulate, secondary type is incurved, two keels on upper surface, short corolla tube, weakly convex in cross-section at widest point, margin is moderately revolute along distal half, longitudinal axis is weak to moderately reflexed along distal quarter, longitudinal axis of ray floret from inner row is moderately incurved along distal quarter, medium to high length to width ratio; pointed, emarginate and mamillate tip; inner side is dark purple red (brighter than RHS 46A), colour of outer side is markedly different from colour of inner side, outer side is brown red (RHS 184C) with lighter tones, in comparison to ray floret from inner row the colour of inner and outer sides is similar, outer side of ray floret from inner row is brown red (RHS 181B-C)

Origin & Breeding History: 'CIDZ0007' 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 a proprietary line designated 'YB-6483' as the female parent, and a proprietary line designated 'YB-A8021' as the male parent. The resultant seed was sown in a greenhouse in October 2006. 'CIDZ0007' 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 'CIDZ0007' 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. Plants of the candidate variety were disbudded. 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.
