| Abstract: |
A distinct cultivar of Chrysanthemum plant named `Sunny Yoshasta`, characterized by its uniform, upright and outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering habit; early flowering habit; numerous daisy-type inflorescences; light yellow-colored ray florets; and excellent postproduction longevity with plants maintaining good substance and color for about four weeks in an interior environment. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named `Sunny Yoshasta`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Chrysanthemum.times.morifolium cultivar Sunny Yoshasta.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium and hereinafter referred to by the name `Sunny Yoshasta`.
The new Chrysanthemum is a naturally-occurring branch mutation of the Chrysanthemum cultivar Shasta, disclosed in U.S. Plant Pat. No. 9,314. The new Chrysanthemum was discovered and selected by the Inventor from within a population of plantsof the parent cultivar in a controlled environment in Travelers Rest, S.C. in February, 1999. The selection of this branch mutation was based on its unique ray floret coloration.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Travelers Rest, S.C. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true totype in successive generations.
SUMMARY OF THE INVENTION
The cultivar Sunny Yoshasta has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sunny Yoshasta`. These characteristics in combination distinguish `Sunny Yoshasta` as a new and distinct Chrysanthemum: 1. Uniform,upright and outwardly spreading plant habit. 2. Strong and freely branching growth habit. 3. Dark green-colored foliage. 4. Uniform flowering habit. 5. Early flowering, 8-week response time. 6. Numerous daisy-type inflorescences. 7. Lightyellow-colored ray florets. 8. Excellent postproduction longevity with plants maintaining good substance and color for about four weeks in an interior environment.
Plants of the new Chrysanthemum differ primarily from plants of the cultivar Shasta in ray floret coloration as plants of the new Chrysanthemum have light yellow-colored ray florets whereas plants of the cultivar Shasta have white-colored rayflorets. In addition, plants of the new Chrysanthemum flower about one to three days later than plants of the parent.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Yochesapeake, disclosed in U.S. Plant Pat. No. 12,535. In side-by-side comparisons conducted in Salinas, Calif., plants of the new Chrysanthemum differed from plants ofthe cultivar Yochesapeake in the following characteristics: 1. Plants of the new Chrysanthemum were shorter and more outwardly spreading than plants of the cultivar Yochesapeake. 2. Plants of the new Chrysanthemum had light yellow-colored ray floretswhereas plants of the cultivar Yochesapeake had darker yellow-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ fromthe color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph at the top of the sheet comprises a side perspective view of typical flowering plants of `Sunny Yoshasta` grown as spray-types.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of `Sunny Yoshasta` grown as spray-types.
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 aforementioned photographs, followingobservations and measurements describe plants grown and flowered during the fall in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During theproduction of these plants, the following conditions were measured: day temperatures, 21 to 27.degree. C.; night temperatures, 17 to l9.degree. C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cmcontainers, exposed to long day/short night conditions, and pinched once about 14 days later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the photographs and description were grown asspray-types. Measurements and numerical values represent averages of typical flowering plants. Botanical classification: Chrysanthemum.times.morifolium cultivar Sunny Yoshasta. Commercial classification: Daisy-type potted Chrysanthemum. Parentage:Naturally-occurring branch mutation of Chrysanthemum.times.morifolium cultivar Shasta, disclosed in U.S. Plant Pat. No. 9,314. Propagation: Type.--Terminal tip cuttings. Time to initiate roots.--About four days at 21.degree. C. Time to produce arooted cutting.--About ten days at 21.degree. C. Root description.--White, close to 155D; fibrous. Rooting habit.--Freely branching. Plant description: Appearance.--Herbaceous daisy-type potted Chrysanthemum that is typically grown as a spray-type.
