Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Chrysanthemum×morifolium cultivar Honey Yoemily.

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 ‘Honey Yoemily’.

The new cultivar is a product of a mutation induction breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the 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 Harvest Emily, disclosed in U.S. Plant Pat. No. 9,075, to X-ray radiation in June, 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 November, 1998. 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 January, 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 Honey Yoemily 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 ‘Honey Yoemily’. These characteristics in combination distinguish ‘Honey Yoemily’ 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.

4. Decorative-type inflorescences.

5. Orange-colored ray florets.

6. Natural season flowering in late September in the Northern Hemisphere.

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

1. Plants of the new Chrysanthemum flowered about 3 to 4 days later than plants of the cultivar Harvest Emily when flowered under natural season conditions.

2. Ray florets of the new Chrysanthemum and the cultivar Harvest Emily differed in ray floret color as ray florets of the cultivar Harvest Emily were darker orange.

Plants of the new Chrysanthemum can be compared to plants of the the cultivar Emily, disclosed in U.S. Plant Pat. No. 7,754. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yoemily in the following characteristics:

1. Plants of the new Chrysanthemum flowered about one week later than plants of the cultivar Emily when flowered under natural season conditions.

2. Ray florets of the new Chrysanthemum and the cultivar Emily differed in ray floret color as ray florets of the cultivar Emily were light purple.

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.
