Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Chrysanthemum×morifolium cultivar Regal Yocheryl.

BACKGROUND OF THE INVENTION

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

The new cultivar is a product of a mutation induction program conducted by the Inventor in Fort Myers, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated by exposing unrooted cuttings of the Chrysanthemum cultivar Yocheryl, disclosed in U.S. Plant Pat. No. 11,846, to X-ray radiation in July, 1998 in Fort Myers, Fla. Following the radiation treatment, the cuttings were rooted and terminal apices were removed (pinched) three times to promote lateral branch development. After lateral branches from the third pinch reached sufficient size, terminal cuttings were harvested, planted and flowered in a controlled environment in Fort Myers, Fla. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within this population in January, 1999. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and good garden performance.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Fort Myers, Fla. since March, 1999, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Regal Yocheryl has 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 ‘Regal Yocheryl’. These characteristics in combination distinguish ‘Regal Yocheryl’ as a new and distinct cultivar:

1. Upright and mounded plant habit.

2. Freely branching habit; dense and full plants.

3. Uniform and freely flowering habit.

4. Decorative-type inflorescences.

5. Purple-colored ray florets.

6. Natural season flowering in early to mid-October in the Northern Hemisphere.

Plants of the new Chrysanthemum are most similar to plants of the the cultivar Yocheryl. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yocheryl in the following characteristics:

1. Ray florets of the new Chrysanthemum were darker purple than ray florets of the cultivar Yocheryl.

2. Ray florets of the new Chrysanthemum faded less than ray florets of the cultivar Yocheryl.

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 close-up view of typical inflorescences of the cultivar ‘Regal Yocheryl’.

DETAILED BOTANICAL DESCRIPTION

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. The following observations and measurements describe plants grown in an outdoor nursery in Pendleton, S.C., under natural season conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One rooted cutting was planted in a 16.5-cm container in late July, 2002. Plants were not pinched, that is, the terminal apex was not removed to enhance branching. During the production of the plants, day temperatures ranged from 29 to 32° C. and night temperatures ranged from 16 to 21° C. Measurements and numerical values represent averages for typical flowering plants.
