Variety used for comparison: 'Yocovington' (Covington)
Summary: The ray florets of 'CIDZ0003' have weakly involute rolling of the margin along the basal half compared to the ray florets of 'Yocovington' which have moderately revolute rolling of the margin along the distal half and only on one margin. The colour of the inner side of the ray floret of 'CIDZ0003' is yellow fading to lighter yellow towards the base with a darker yellow tip while for 'Yocovington', the colour is lighter yellow. The colour of the outer side of the ray floret compared to the colour of the inner side is markedly different for 'CIDZ0003' while they are similar for 'Yocovington'. The colour of the outer side is light yellow for 'CIDZ0003' whereas it is yellow green for 'Yocovington'.
PLANT: pot chrysanthemum, bushy type, upright to semi-upright growth habit, sparse to medium branching
PETIOLE: attitude is moderately upwards to horizontal, medium length relative to leaf length
LEAF: medium 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, 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 HEAD: double, low to medium height in non-disbudded plants, medium to dense ray florets
RAY FLORET: ligulate type, attitude of basal part is moderately ascending to horizontal, short corolla tube, weakly concave in cross-section at widest point, weakly involute margins, longitudinal axis ranges from very weakly incurved along distal quarter to straight, longitudinal axis of ray floret from inner row is moderately incurved along distal quarter, medium to high length to width ratio, mamillate tip, inner side is yellow (RHS 6A) fading to lighter yellow (RHS 6B) towards base with darker yellow (RHS 9A) tip, colour of outer side is markedly different from colour of inner side, outer side is light yellow (closest to RHS 8B), in comparison to ray floret from inner row the colour of inner and outer sides is similar
Origin & Breeding History: 'CIDZ0003' originated from a controlled cross-pollination conducted in May 2005, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-A7604' as the female parent, and a proprietary line designated 'YB-A5705' as the male parent. The resultant seed was sown in a greenhouse in October 2005. 'CIDZ0003' was selected as a single plant from the progeny in May 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 'CIDZ0003' 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 15, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
