| Abstract: |
A distinct cultivar of Chrysanthemum plant named `Treat`, characterized by its upright plant habit; large decorative spider-type inflorescences that are about 17 cm in diameter; attractive bright yellow-colored ray florets; response time about 53 days; dark green-colored foliage; strong and thick flowering stems; and excellent postproduction longevity with inflorescences and foliage maintaining good substance and color for about 21 days in an interior environment. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named `Treat`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Chrysanthemum.times.morifolium cultivar Treat.
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 `Treat`.
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 October, 1998, in Salinas, Calif., of a proprietary Chrysanthemum.times.morifolium seedling selection identified as code number R089, not patented, as the female,or seed, parent with a proprietary Chrysanthemum.times.morifolium seedling selection identified as R210, not patented, as the male, or pollen, parent.
The cultivar Treat 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 November, 1999. 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 February, 2000, 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 Treat 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 `Treat`. These characteristics in combination distinguish `Treat` as a new and distinct cultivar: 1. Upright cut Chrysanthemum that isusually grown as a disbud. 2. Large decorative spider-type inflorescences that are about 17 cm in diameter. 4. Attractive bright yellow-colored ray florets. 5. Response time about 53 days. 6. Dark green foliage. 7. Strong and thick floweringstems. 8. Excellent postproduction longevity with inflorescences and foliage maintaining good substance and color for about 21 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 from plants of the female parent selection in the followingcharacteristics: 1. Plants of the new Chrysanthemum had taller flowering stems than plants of the female parent selection. 2. Plants of the new Chrysanthemum had larger inflorescences than plants of the female parent selection.
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 produced very few disc florets and no pollen whereas plants of the male parent selection produce many disc florets with pollen. 2. Ray florets of plants of the new Chrysanthemum and themale parent selection differed in coloration as ray florets of the male parent selection were white in color.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum.times.morifolium cultivar Super Yellow, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plantsof the cultivar Super Yellow in the following characteristics: 1. Plants of the new Chrysanthemum had taller flowering stems than plants of the cultivar Super Yellow. 2. Plants of the new Chrysanthemum flowered about ten days earlier than plants ofthe cultivar Super Yellow. 3. Plants of the new Chrysanthemum had larger and more uniform inflorescences than plants of the cultivar Super Yellow. 4. Ray floret color of plants of the new Chrysanthemum was darker yellow than ray floret color ofplants of the cultivar Super Yellow.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 photograph may differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum. The photograph comprises a side perspective view of a typical flowering stem of `Treat` grown as a disbud.
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 La Ceja, Antioquia, Colombia, South America, under conditions which approximate commercial practice in a single-layer polyethylene-covered greenhouse. Two-week old rooted cuttings were planted onAug. 19, 2002 and received 14 long day/short nights followed by short day/long nights until flowering. Plants were grown as disbudded cut Chrysanthemums. During the production time, the following environmental conditions were measured: daytemperatures, 20 to 27.degree. C.; night temperatures, 8 to 13.degree. C.; and light levels, 4,000 to 6,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about ten weeks afterthe start of short days. Botanical classification: Chrysanthemum.times.morifolium cultivar Treat. Commercial classification: Decorative spider-type cut Chrysanthemum.
