Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Golden Yohelga’, characterized by its upright and outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; large decorative-type inflorescences with elongated oblong-shaped ray florets; bright yellow-colored ray florets; and natural season flowering in mid September in the Northern Hemisphere.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Golden Yohelga.
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 ‘Golden Yohelga’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Alva, 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 is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Yohelga, disclosed in U.S. Plant Pat. No. 13,811. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the cultivar Yohelga in a controlled environment in Alva, Fla. in April, 2002. 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 vegetative cuttings in a controlled environment in Alva, Fla. since June, 2002, 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 Golden Yohelga 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 ‘Golden Yohelga’. These characteristics in combination distinguish ‘Golden Yohelga’ as a new and distinct cultivar:
1. Upright and outwardly spreading plant habit.
2. Freely branching habit; dense and full plants.
3. Uniform and freely flowering habit.
4. Large decorative-type inflorescences with elongated oblong-shaped ray florets.
5. Bright yellow-colored ray florets.
6. Natural season flowering in mid September 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 Yohelga, primarily in ray floret coloration as plants of the cultivar Yohelga had creamy white-colored ray florets. In addition, plants of the new Chrysanthemum flowered about one day later than plants of the cultivar Yohelga when grown under natural season conditions.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Janice, disclosed in U.S. Plant Pat. No. 9,817. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Janice in the following characteristics:
1. Plants of the new Chrysanthemum flowered about five days earlier than plants of the cultivar Janice when grown under natural season conditions.
2. Plants of the new Chrysanthemum flowered later than plants of the cultivar Janice when grown under artificial short day/long night photoperiodic conditions.
3. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Janice.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Gedi One Avi, disclosed in U.S. Plant Pat. No. 13,455. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Gedi One Avi in the following characteristics:
1. Plants of the new Chrysanthemum flowered about ten days earlier than plants of the cultivar Gedi One Avi when grown under natural season conditions.
2. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Gedi One Avi.
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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘Golden Yohelga’ grown in a container.
The photograph on the second sheet comprises a close-up view of typical inflorescences of the cultivar ‘Golden Yohelga’.
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 Alva, Fla. during the winter in a fiberglass-covered greenhouse under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was planted in a 15.25-cm container in early December, 2002. Plants were pinched one time, that is, the terminal apex was removed to enhance branching, at the end of December. One week after the pinch, plants were exposed to short day/long night photoperiodic treatments until flowering. During the production of the plants, day temperatures averaged 26° C. and night averaged 18° C. Measurements and numerical values represent averages for typical flowering plants.
