Variety Description

Variety used for comparison: 'Yobethany' (Bethany)

Summary: The indentations along the leaf margin are medium in number and of medium depth for 'CIFZ0025' whereas the indentations of 'Yobethany' are absent or very few in number and shallow. On non-disbudded plants, the flower head of 'CIFZ0025' is larger in diameter and taller with larger ray florets than the flower head of 'Yobethany'. The flower head of 'CIFZ0025' contains only ligulate type ray florets whereas the flower head of 'Yobethany' has both ligulate and spatulate type ray florets. The profile of the ray floret in cross section at the widest point is flat or weakly convex for 'CIFZ0025' whereas the profile of the ray floret is strongly concave with margins touching towards its base for 'Yobethany'. The ray floret of 'CIFZ0025' is incurved, reflexed and twisted along the longitudinal axis whereas the ray floret of 'Yobethany' is straight. The colour of the inner side of the ray floret of 'CIFZ0025' is yellow whereas the inner side of the ray floret of 'Yobethany' is darker yellow.

Origin & Breeding History: 'CIFZ0025' was discovered and developed as part of a controlled breeding program at Syngenta Flowers Inc., in Gilroy, California, USA. It originated from a whole plant mutation of a proprietary line designated 'G0495K4'. It was discovered in March 2011 by the breeder, Mark A. Smith, in Amanecer, Columbia, USA. 'CIFZ0025' selection was based on its flower colour. The first propagation of 'CIFZ0025' using asexual reproduction occurred in April 2011, in Gilroy, California, USA.

Tests & Trials: The trial of 'CIFZ0025' 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 26, 2013 except flower measurements, which were taken on October 3, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
