Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Date’.
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 desirable colors and good form and substance.
The new Chrysanthemum originated from a cross made by the Inventor in April, 1997, in Salinas, Calif., of the Chrysanthemum cultivar Preludio, not patented, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as 3499, not patented, as the male, or pollen, parent.
The cultivar Date was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in March, 1998. 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 taken in a controlled environment in Alva, Fla. since June, 1998, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Date 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 in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Date’. These characteristics in combination distinguish ‘Date’ as a new and distinct cultivar:
1. Upright cut Chrysanthemum that can be grown as a disbud or as a natural spray.
2. Large quilled decorative-type inflorescences that are about 12.3 cm in diameter when grown as a disbud and about 9.3 cm in diameter when grown as a natural spray.
3. Attractive purple-colored inflorescences.
4. Response time about 62 days when grown as a disbud and about 68 to 70 days when grown as a natural spray.
5. Dark green foliage.
6. Strong and thick stems.
7. Excellent postproduction longevity with inflorescences maintaining good substance and color for at least three weeks in an interior environment.
Compared to plants of the female parent, the cultivar Preludio, plants of the new Chrysanthemum produce heavier flowering stems. In addition, plants of the new Chrysanthemum and the cultivar Preludio differ in ray floret form as ray florets of the cultivar Preludio are spooned and have small hooks at the apex.
Plants of the new Chrysanthemum and the male parent, the seedling selection identified as code number 3499, differ in inflorescence form as inflorescences of the male parent are spooned daisy-types with three to four rows of ray florets and numerous disc florets. In addition, inflorescences of plants of the male parent are bright yellow in color.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Dance, disclosed in U.S. Plant Pat. No. 12,941. However, in side-by-side comparisons conducted by the Inventor in Madrid, Cundinamarca, Colombia, South America, plants of the new Chrysanthemum are more vigorous, produce heavier flowering stems, have larger inflorescences and have darker ray floret coloration than plants of the cultivar Dance.
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 slightly 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 ‘Date’ grown as a natural spray.
The photograph at the top of the second sheet comprises a close-up view of a typical flowering stem of ‘Date’ grown as a natural spray.
The photograph at the bottom of the second sheet comprises a close-up view of a typical flowering stem of ‘Date’ grown as a disbud.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations 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 on Nov. 30, 2000 and received 14 long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem disbud and natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 19 to 24° C.; night temperatures, 4 to 12° 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 9 to 10 weeks after the start of short days.
