Variety Description

Variety used for comparison: 'Yoheidi' (Heidi)

Summary: Plants of 'CIFZ0013' are broader than plants of 'Yoheidi'. 'CIFZ0013' has a longer leaf than 'Yoheidi'. Relative to the leaf length, the petiole length is medium to long for 'CIFZ0013' whereas the petiole length is short to medium length for 'Yoheidi'. Relative to the leaf length, the length of the terminal leaf lobe is long for 'CIFZ0013' whereas the length of the terminal leaf lobe of 'Yoheidi' is short. The depth of the lowest lateral sinus is deep for 'CIFZ0013' whereas the lowest lateral sinus of 'Yoheidi' is shallow. The margin of the leaf of 'CIFZ0013' has a medium number of indentations whereas the leaf margin of 'Yoheidi' has no indentations. On non-disbudded plants, the density of ray florets of the flower head of 'CIFZ0013' is medium to dense whereas the ray florets of the flower head of 'Yoheidi' are very dense. When comparing a ray floret from the inner and outer row of the flower head of 'CIFZ0013', the profile along the longitudinal axis is different whereas a ray floret from the inner and outer row of the flower head of 'Yoheidi' has the same profile along the longitudinal axis. 'CIFZ0013' has a larger disc diameter than 'Yoheidi'.

Origin & Breeding History: 'CIFZ0013' was bred and developed as part of a controlled breeding program at Syngenta Flowers Inc., in Gilroy, California, USA. It originated from a cross made by the breeder, Mark A. Smith, in Amanecer, Columbia, USA, between the variety 'Yoelena' as the female parent, and the proprietary line designated 'G0248F6' as the male parent. The resultant seed was sown in a greenhouse in June 2008, in Alva, Florida, USA. 'CIFZ0013' was selected in October 2008 based on its flower colour and plant growth habit.

Tests & Trials: The trial of 'CIFZ0013' was conducted as an outdoor irrigated trial during the fall of 2013 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants of the candidate variety and 15 plants of the reference variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on June 25, 2013. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate and reference varieties on September 13, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
