RAY FLORET: ligulate type, attitude of basal part is moderately ascending to horizontal, two keels on upper surface, short corolla tube, flat in cross-section at widest point, rolling of margins ranges from flat to weakly revolute along middle half, longitudinal axis is straight, longitudinal axis of ray floret from inner row is weakly incurved along distal quarter, medium length to width ratio, dentate and emarginate tip, inner side is light yellow (RHS 8B), colour of outer side is similar to colour of inner side, outer side is light yellow (RHS 8C), in comparison to ray floret from inner row the colour of inner and outer sides is similar

Origin & Breeding History: 'CIFZ0024' originated from a naturally occurring whole plant mutation of a proprietary, unnamed sport of the variety 'Jacqueline'. It was discovered and selected on March 9, 2009 by the breeder, Mark A. Smith, in Alva, Florida, USA. Selection of 'CIFZ0024' was based on its plant growth habit, natural season response time, and flower size and type.

Tests & Trials: The trial for 'CIFZ0024' was conducted as an outdoor irrigated trial during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants of the candidate variety and 12 plants of the reference variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on June 11, 2012. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate and reference varieties on September 24, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
