| Abstract: |
A distinct cultivar of Chrysanthemum plant named `True`, characterized by its upright plant habit; freely flowering habit; decorative-type inflorescences that are about 6.9 cm in diameter; attractive dark red purple-colored ray florets; response time about 64 days; dark green foliage; strong and thick flowering stems and peduncles; and good postproduction longevity with inflorescences and foliage maintaining good substance and color for about 14 to 18 days in an interior environment. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named `True`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Chrysanthemum.times.morifolium cultivar True.
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 `True`.
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 breeding program is to create new cut Chrysanthemum cultivars having inflorescences with desirablecolors and good form and substance.
The new Chrysanthemum originated from a cross-pollination made by the Inventor in March, 1996, in Salinas, Calif., of a proprietary Chrysanthemum.times.morifolium seedling selection identified as code number C911, not patented, as the female, orseed, parent with a proprietary Chrysanthemum.times.morifolium seedling selection identified as D458, not patented, as the male, or pollen, parent.
The cultivar True was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., in March, 1997. The selection of this plant was based on itsdesirable inflorescence color and good form and substance.
Asexual reproduction of the new Chrysanthemum by terminal cuttings taken in a controlled environment in Alva, Fla. since June, 1997, 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 True 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 variance ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `True`. These characteristics in combination distinguish `True` as a new and distinct cultivar: 1. Upright cut Chrysanthemum that isusually grown as a natural spray. 2. Freely flowering habit, about six or seven inflorescences per flowering stem. 3. Decorative-type inflorescences that are about 6.9 cm in diameter. 4. Attractive dark red purple-colored ray florets. 5. Responsetime about 64 days. 6. Dark green foliage. 7. Strong and thick flowering stems and peduncles. 8. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about 14 to 18 days in an interior environment.
Plants of the new Chrysanthemum can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed primarily from plants of the female parent selection in rayfloret coloration as plants of the female parent selection had bronze orange-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed primarily from plants of the male parent selection in thefollowing characteristics: 1. Plants of the new Chrysanthemum were more freely flowering than plants of the male parent selection. 2. Inflorescences of plants of the new Chrysanthemum did not produce pollen whereas inflorescences of plants of the maleparent selection produced a moderate amount of pollen.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum.times.morifolium cultivar Dark Flamenco, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plantsof the cultivar Dark Flamenco in the following characteristics: 1. Flowering stems of plants of the new Chrysanthemum were taller than flowering stems of plants of the cultivar Dark Flamenco. 2. Plants of the new Chrysanthemum flowered about sevendays earlier than plants of the cultivar Dark Flamenco. 3. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Dark Flamenco. 4. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivarDark Flamenco.
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 differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph on the first sheet comprises a side perspective view of a typical flowering stem of `True` grown as a natural spray.
The photograph on the second sheet comprises a close-up view of a typical flowering stem of `True` 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 Madrid, Cundinamarca, Colombia, South America, under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Two-week old rooted cuttings were planted onAug. 20, 2002 and received 17 long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured:day temperatures, 19 to 24.degree. C.; night temperatures, 4 to 12.degree. C.; and light levels, 3,000 to 5,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about ten weeksafter the start of short days.
