Description

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘CIDZ0026’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘CIDZ0026’.

‘CIDZ0026’ is a product of a planned breeding program. The new cultivar has pure white inflorescence color, a very green disc that develops a dark dot in the middle when plants are grown under high light and low temperatures, very uniform growth habit, and a 7½ week flowering response.

‘CIDZ0026’ originated from a hybridization made in February 2008 in a greenhouse in Bogota, Colombia. The female parent was an unpatented, proprietary plant designated ‘YB-A9617’. ‘YB-A9617’ has smaller white inflorescences, smaller plant size, and a slower flowering response than ‘CIDZ0026’.

The male parent of ‘CIDZ0026’ was an unpatented, proprietary plant identified as ‘YB-B2756’. ‘YB-B2756’ has larger, more ivory colored inflorescences and has a slower flowering response that ‘CIDZ0026’.

The resultant seed was sown in a shade structure in July 2008 in Fort Myers, Fla. ‘CIDZ0026’ was selected as one flowering plant within the progeny of the stated cross in December 2008, grown in pots under a shade structure in Fort Myers, Fla.

The first act of asexual reproduction of ‘CIDZ0026’ was accomplished when vegetative cuttings were propagated from the initial selection in March 2009 in a greenhouse in Fort Myers, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in March 2009, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CIDZ0026’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CIDZ0026’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Jul. 29, 2011, No. 11-7347. ‘CIDZ0026’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘CIDZ0026’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a close-up of the flowers and in FIG. 2, 4 flowering plants of the new variety.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in January 2012 under natural light. These plants were grown 4 plants in a 5-inch pot under center bud removal and blackcloth controlled greenhouse trial conditions in Gilroy, Calif. These plants were 10-12 weeks old.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
