Variety Description

Variety used for comparison: 'Pink Yograceland' (Graceland Pink)

Summary: The margins of the lowest lateral sinus of the leaf are parallel for 'CIDZ0012' while they are diverging for 'Pink Yograceland'. The predominant shape of the leaf base is truncate for 'CIDZ0012' while it is obtuse for 'Pink Yograceland'. 'CIDZ0012' has a smaller flower head diameter with a shorter and more narrow ray floret than 'Pink Yograceland'. The colour of the outer side of the ray floret of 'CIDZ0012' is white with light blue violet overcolour and violet central bar on the distal three quarters whereas the outer side of the ray floret of 'Pink Yograceland' is white with light blue pink overcolour and light blue violet fading to white at base. 'CIDZ0012' has a larger disc diameter than 'Pink Yograceland'. Before anther dehiscence, the colour of the apex of the disc is blue pink for 'CIDZ0012' while it is yellow green for 'Pink Yograceland'. At anther dehiscence, the colour of the disc of 'CIDZ0012' is white with a light blue violet flush whereas the disc of 'Pink Yograceland' is yellow.

Origin & Breeding History: 'CIDZ0012' originated from a controlled cross-pollination conducted in February 2007, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved variety 'Yovisalia' as the female parent, and a proprietary line designated 'YB-B1665' as the male parent. The resultant seed was sown in a greenhouse in July 2007. 'CIDZ0012' was selected as a single plant from the progeny in December 2007 by the breeder, Wendy R. Bergman, in Alva, Florida, USA, based on its flower colour, plant growth habit, and production characteristics.

Tests & Trials: The trial for 'CIDZ0012' 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 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
