Abstract

A new Chrysanthemum plant named ‘CIFZ0023’ particularly distinguished by the medium sized pure white decorative inflorescences, medium sized plant habit with a rounded and mounded habit, and a natural season flowering response of early October.

Description

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

Varietal denomination: ‘CIFZ0023’.

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 ‘CIFZ0023’.

‘CIFZ0023’ is a product of a planned breeding program. The new cultivar has medium sized pure white decorative inflorescences, medium sized plant habit with a rounded and mounded habit, and a natural season flowering response of early October.

‘CIFZ0023’ originated from a hybridization made in January 2008 in a greenhouse in Tenjo, Columbia. The female parent was the proprietary patented plant designated ‘Yoalexis’, U.S. Plant Pat. No. 15,318, with creamy white inflorescence color and a taller plant habit in natural season crops, with a lighter green foliage that is less likely to turn yellow in cool growing crops when compared to ‘CIFZ0023’.

The male parent of ‘CIFZ0023’ was the unpatented, proprietary plant designated as ‘03-M342’ with yellow inflorescences and more disk florets, smaller overall plant size and a natural season flowering response that is up to four weeks faster when compared to ‘CIFZ0023’. The resultant seed was sown and grown outdoors in June 2009 in Alva, Fla. USA.

‘CIFZ0023’ was selected as one flowering plant within the progeny of the stated cross in November 2009 in Alva, Fla.

The first act of asexual reproduction of ‘CIFZ0023’ was accomplished when vegetative cuttings were propagated from the initial selection in January 2010 in a greenhouse in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in January 2010, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CIFZ0023’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CIFZ0023’ 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 Mar. 8, 2013, No. 13-7958. ‘CIFZ0023’ 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 drawing shows typical flower and foliage characteristics of ‘CIFZ0023’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows a flowering plant of the new variety and a close-up of the inflorescences.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in August outdoors under natural light from plants that were about 11 weeks old. These plants were grown in 6 inch pots in a greenhouse trial under blackcloth conditions. These plants were not pinched.

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