Chrysanthemum plant named ‘Sparkling Yocheryl’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Sparkling Yocheryl’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; decorative-type inflorescences with elongated oblong to ligulate-shaped ray florets; yellow-colored ray florets; and natural season flowering about October 5th in the Northern Hemisphere.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Sparkling Yocheryl’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a garden Chrysanthemum and hereinafter referred to by the name ‘Sparkling Yocheryl’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Golden Yocheryl, disclosed in U.S. Plant Pat. No. 16,383. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of plants of the parent cultivar in October, 2004, in Morris, Connecticut. The selection of this plant was based on its desirable inflorescence color and good form and substance.

Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in Gainesville, Fla. in March, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sparkling Yocheryl have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sparkling Yocheryl’. These characteristics in combination distinguish ‘Sparkling Yocheryl’ as a new and distinct garden Chrysanthemum cultivar:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Uniform and freely flowering habit.
  • 4. Decorative-type inflorescences with elongated oblong to ligulate-shaped ray florets.
  • 5. Yellow-colored ray florets.
  • 6. Natural season flowering about October 5^th in the Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla. plants of the new Chrysanthemum differed from plants of the parent, the cultivar Golden Yocheryl, in the following characteristics:

• • 1. Plants of the new Chrysanthemum were slightly smaller than plants of ‘Golden Yocheryl’.
  • 2. Plants of the new Chrysanthemum and the cultivar Golden Yocheryl differed in ray floret coloration.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yoerica, disclosed in U.S. Plant Pat. No. 11,842. In side-by-side comparisons conducted in Alva, Fla. plants of the new Chrysanthemum differed from plants of the cultivar Yoerica in the following characteristics:

• • 1. Plants of the new Chrysanthemum had darker green-colored leaves than plants of the cultivar Yoerica.
  • 2. Plants of the new Chrysanthemum flowered later than plants of the cultivar Yoerica.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Sparkling Yocheryl’.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Sparkling Yocheryl’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Fletcher, N.C. during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial garden Chrysanthemum production. During the production of the plants, day temperatures averaged 29° C. and night temperatures averaged 16° C. Plants were grown in 15-cm containers, exposed to long day/short night conditions and pinched about two weeks later. About two weeks after the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description were about three months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
