ABSTRACT:

Botanical classification/cultivar designation:
Chrysanthemum×morifolium
cultivar Yellow Chablis.
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 ‘Yellow Chablis’.
The new cultivar is a product of a mutation induction program conducted by the Inventor in Alva, 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 Empire Chablis, disclosed in U.S. Plant Pat. No. 8,986, to X-ray radiation in June, 1999 in Alva, Fla. Following the radiation treatment, the cuttings were rooted and terminal apices were removed to promote lateral branch development. After lateral branches from the pinch reached sufficient size, terminal cuttings were harvested, planted and flowered in a controlled environment in Alva, Fla. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within this population in November, 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 Alva, Fla. since January, 2000, 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 Yellow Chablis 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 ‘Yellow Chablis’. These characteristics in combination distinguish ‘Yellow Chablis’ as a new and distinct cultivar:
1. Upright, outwardly spreading and mounded plant habit.
2. Freely branching habit; dense and full plants.
3. Uniform and freely flowering habit.
4. Large decorative-type inflorescences.
5. Bright yellow-colored ray florets with darker yellow-colored disc florets.
6. Natural season flowering in early September in the Northern Hemisphere.
Plants of the new Chrysanthemum are most similar to plants of the the cultivar Empire Chablis. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Empire Chablis in the following characteristics:
1. Plants of the new Chrysanthemum flowered about two days earlier than plants of the cultivar Empire Chablis.
2. Ray florets of the new Chrysanthemum and the cultivar Empire Chablis differed in color as ray florets of the cultivar Empire Chablis were white.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Jessica, disclosed in U.S. Plant Pat. No. 7,587. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Jessica in the following characteristics:
1. Plants of the new Chrysanthemum were more upright than plants of the cultivar Jessica.
2. Plants of the new Chrysanthemum flowered about two weeks earlier than plants of the cultivar Jessica.
3. Plants of the new Chrysanthemum had larger inflorescences and more disc florets per inflorescence than plants of the cultivar Jessica.
4. Ray floret color of plants of the new Chrysanthemum did not fade as readily as ray floret color of plants of the cultivar Jessica.
