ABSTRACT:

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.
