Summary: Just before opening, the colour of the outer side of the flower bud is orange brown for 'CIDZ0034' whereas the flower bud of 'Red Yoirvine' is brown red with brown purple at the base. The disc of 'CIDZ0034' is anemone type while the disc of 'Red Yoirvine' is daisy type. 'CIDZ0034' has a larger flower head diameter, and a longer ray floret than 'Red Yoirvine'. The height of the flower head of 'CIDZ0034' is low while the flower head of 'Red Yoirvine' is very low. The attitude of the basal part of the ray floret of 'CIDZ0034' is moderately ascending while the base of the ray floret of 'Red Yoirvine' is horizontal to moderately descending. The ratio of length to width of the ray floret of 'CIDZ0034' is high while it is medium for 'Red Yoirvine'. The colour of the outer side of the ray floret of 'CIDZ0034' is yellow brown with brown red mottling whereas the outer side of the ray floret of 'Red Yoirvine' is light yellow brown with red pink mottling. The disc diameter relative to the diameter of the flower head is medium for 'CIDZ0034' while it is small for 'Red Yoirvine'.

DISC: diameter relative to head diameter is medium, light yellow brown (closest to RHS 160A) before anther dehiscence, brown red (redder than RHS 179A) with yellow (RHS 3A) at margin at anther dehiscence
DISC FLORET: funnel type, outer side is light yellow brown (RHS 160B) with brown red (RHS 182A, 181C) stripes, inner side is brown red (redder than RHS 179A) with yellow (RHS 3A) margin

Origin & Breeding History: 'CIDZ0034' originated from a controlled cross-pollination conducted in March 2008, in Bogota, Columbia, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-B2899' as the female parent, and a proprietary line designated 'YB-B2956' as the male parent. The resultant seed was sown in a greenhouse in October 2008. 'CIDZ0034' was selected as a single plant from the progeny in March 2009 by the breeder, Wendy R. Bergman, based on its flower colour, and plant growth habit.

Tests & Trials: The trial for 'CIDZ0034' 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 13, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
