| Abstract: |
A new and distinct cultivar of Chrysanthemum plant named `Yellow Sharp`, characterized by its upright plant habit; dark green-colored foliage; freely and uniformly flowering habit; quilled decorative-type inflorescences that are about 5.5 cm in diameter with bright yellow-colored ray florets and green-colored centers; strong peduncles; and good postproduction longevity. |
| Claim: |
It is claimed:
1. A new and distinct Chrysanthemum plant named `Yellow Sharp` as illustrated and described. |
| Description: |
Botanical classification:Chrysanthemum.times.morifolium.
Cultivar denomination: `Yellow Sharp`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium, commercially grown as a cut flower and hereinafter referred to by the name `Yellow Sharp`.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Bogota, Colombia. The objective of the program is to create and develop new cut Chrysanthemum cultivars having inflorescences withdesirable floret coloration and good inflorescence form and substance.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum.times.morifolium cultivar Sharp, disclosed in U.S. Plant Pat. No. 13,439. The new Chrysanthemum was discovered and selected by the Inventor as a singleflowering plant within a population of plants of the cultivar Sharp in November, 2002, in Bogota, Colombia. The selection of this plant was based on its desirable inflorescence color and good form and substance.
Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Bogota, Colombia since February, 2003, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type insuccessive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Yellow Sharp have 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Yellow Sharp`. These characteristics in combination distinguish `Yellow Sharp` as a new and distinct cultivar of Chrysanthemum: 1. Upright cut Chrysanthemum that is usually grown as a naturally spray. 2. Dark green-colored foliage. 3. Freely and uniformly flowering habit. 4. Quilled decorative-type inflorescences that are about 5.5 cm in diameter with bright yellow-colored rayflorets and green-colored centers. 5. Response time about 63 days. 6. Strong peduncles. 7. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about two weeks in an interior environment.
Plants of the new Chrysanthemum differ from plants of the parent, the cultivar Sharp, in the following characteristics: 1. Plants of the new Chrysanthemum flower slightly later than plants of the cultivar Sharp. 2. Plants of the newChrysanthemum and the cultivar Sharp differ in ray floret color as ray florets of plants of the cultivar Sharp are white in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar White Yoneedle, disclosed in U.S. Plant Pat. No. 18,135. In side-by-side comparisons conducted in Bogota, Colombia, plants of the new Chrysanthemumdiffered from plants of the cultivar White Yoneedle in the following characteristics: 1. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar White Yoneedle. 2. Plants of the new Chrysanthemum and the cultivar WhiteYoneedle differed in ray floret color as plants of the cultivar White Yoneedle had white-colored ray florets. 3. Plants of the new Chrysanthemum had shorter peduncles than plants of the cultivar White Yoneedle.
BRIEF DESCRIPTION OF THEPHOTOGRAPHS
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 maydiffer slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering stem of `Yellow Sharp` grown as a natural spray.
The photograph at the top of the sheet comprises a close-up view of typical inflorescences of `Yellow Sharp` grown as a natural spray.
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 and followingobservations and measurements describe plants grown in Oxnard, Calif. during the winter and spring in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial Chrysanthemum production. Measurements and numerical values represent averages for typical flowering plants. Plants were grown as single-stem natural spray cut Chrysanthemums. The photographs and measurements were taken when plants were about three months old. Botanicalclassification: Chrysanthemum.times.morifolium cultivar Yellow Sharp. Parentage: Naturally-occurring whole plant mutation of the Chrysanthemum.times.morifolium cultivar Sharp, disclosed in U.S. Plant Pat. No. 13,439. Propagation: Type.--Terminalvegetative cuttings. Time to initiate roots.--About ten to 14 days with soil temperatures of about 18.degree. C. to 21.degree. C. Root description.--Fine, fibrous; white in color. Rooting habit.--Freely branching. Plant description:Appearance.--Herbaceous decorative-type cut flower that is typically grown as a natural spray. Flowering stem description.--Aspect: Erect. Length: About 114 cm. Diameter: About 6 mm. Internode length: About 4 cm. Texture: Pubescent; longitudinallyridged. Color: 146C. Foliage description.--Arrangement: Alternate; simple. Length: About 10.5 cm. Width: About 5.8 cm. Apex: Acuminate. Base: Attenuate. Margin: Palmately lobed; sinuses parallel to divergent. Texture, upper and lower surfaces:Pubescent; veins prominent on lower surface. Color: Developing foliage, upper surface: 147A. Developing foliage, lower surface: 146A. Fully expanded foliage, upper surface: 147A; venation, 147C.
