| Claim: |
It is claimed:
1. A new and distinct Chrysanthemum plant named `Yodrum` as illustrated and described. |
| Description: |
Botanical designation:Chrysanthemum.times.morifolium.
Cultivar denomination: `Yodrum`.
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 `Yodrum`.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. 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 originated from a cross-pollination made by the Inventor in March, 1999, in Salinas, Calif. of a proprietary selection of Chrysanthemum.times.morifolium identified as code number R834, not patented, as the female, or seed,parent with a proprietary selection of Chrysanthemum.times.morifolium identified as code number 1092, not patented not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single floweringplant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla. in March, 2000. The selection of this plant was based on its desirable ray floret color and good inflorescence form and substance.
Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Alva, Fla. since May, 2000, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successivegenerations.
SUMMARY OF THE INVENTION
Plants of the cultivar Yodrum 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, any variancein genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Yodrum`. These characteristics in combination distinguish `Yodrum` as a new and distinct cultivar of Chrysanthemum: 1. Upright planthabit. 2. Dark green-colored foliage. 3. Freely and uniformly flowering habit. 4. Decorative-type inflorescences that are about 6 cm to 7 cm in diameter. 5. Attractive dark orange-colored ray florets. 6. Response time about 59 days. 7. Strongpeduncles. 8. 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 female parent selection in the following characteristics: 1. Plants of the new Chrysanthemum are shorter than plants of the female parent selection. 2. Plants of the new Chrysanthemumare more freely flowering than plants of the female parent selection. 3. Plants of the new Chrysanthemum flower earlier than plants of the female parent selection.
Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Chrysanthemum are shorter than plants of the male parent selection. 2. Plants of the new Chrysanthemumflower earlier and more freely than plants of the male parent selection. 3. Plants of the new Chrysanthemum and the male parent selection differ in ray floret color as plants of the male parent selection have light pink-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Falma, disclosed in U.S. Plant Pat. No. 5,996. In side-by-side comparisons conducted in Alva, Fla. plants of the new Chrysanthemum differed from plants ofthe cultivar Falma in the following characteristics: 1. Plants of the new Chrysanthemum flowered earlier and more freely than plants of the cultivar Falma. 2. Plants of the new Chrysanthemum had slightly larger inflorescences than plants of thecultivar Falma. 3. Plants of the new Chrysanthemum had shorter peduncles than plants of the cultivar Falma.
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 maydiffer slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysantheum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of `Yodrum`.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of `Yodrum`.
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 Bogota, Colombia during the summer in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial Chrysanthemum production. During theproduction of the cut flowers, day temperatures ranged from 20.degree. C. to 25.degree. C., night temperatures ranged from 4.degree. C. to 9.degree. C. and light levels ranged from 3,000 to 4,000 footcandles. Measurements and numerical valuesrepresent averages for typical flowering plants. The photographs and measurements were taken when plants were about two months old from planting. Botanical classification: Chrysanthemum.times.morifolium cultivar Yodrum. Parentage: Female, or seed,parent.--Proprietary selection of Chrysanthemum.times.morifolium identified as code number R834, not patented. Male, or pollen, parent.--Proprietary selection of Chrysanthemum.times.morifolium identified as code number 1092, not patented. Propagation:Type.--Terminal vegetative cuttings.
