Variety used for comparison: 'Yobarbie' (Barbie)

Summary: The colour of the stem of 'CIFZ0010' is green tinged with purple or brown whereas the stem of 'Yobarbie' is only green. 'CIFZ0010' has a wider leaf than 'Yobarbie'. The predominant shape of the base of the leaf is obtuse for 'CIFZ0010' whereas the base of the leaf of 'Yobarbie' is cordate. Just before opening, the colour on the outer side of the flower bud of 'CIFZ0010' is dark purple red whereas the outer side of the flower bud of 'Yobarbie' is blue pink. The flower head type of 'CIFZ0010' is daisy-eyed double whereas the flower head type of 'Yobarbie' is double. On non-disbudded plants, the flower head of 'CIFZ0010' is larger in diameter with a longer and narrower ray floret than the flower head of 'Yobarbie'. The profile of the ray floret in cross section at the widest point is flat to weakly convex for 'CIFZ0010' whereas the ray floret in cross section is strongly concave for 'Yobarbie'. When comparing the colour of the inner side of the ray floret to the colour of the outer side of the ray floret, the two colours are similar for 'CIFZ0010' whereas the two colours are markedly different for 'Yobarbie'. When grown without precise day length control, the natural flowering period of the plants of 'CIFZ0010' begins sooner than the natural flowering period of the plants of 'Yobarbie'.

Origin & Breeding History: 'CIFZ0010' was discovered and developed as part of a controlled breeding program at Syngenta Flowers Inc., in Gilroy, California, USA. It originated from a naturally occurring whole plant mutation of a line designated '07-M322'. It was discovered in March 2010 by the breeder, Mark A. Smith, in Gilroy, California, USA. 'CIFZ0010' selection was based on its flower colour and plant growth habit.

Tests & Trials: The trial of 'CIFZ0010' 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 chrysanthemum pans on June 25, 2013. Observations and measurements were taken from 10 plants, or parts of plants on October 3, 2013 for the candidate variety and on October 9, 2013 for the reference variety. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
