Abstract
A new and distinct cultivar of Chrysanthemum plant named ‘Dekyazoo’, characterized by its large decorative-type inflorescences with white-colored quilled ray florets; strong and upright flowering stems; short response time; uniform flowering habit; and excellent postproduction longevity; plants maintain good substance for about three weeks in an interior environment.
Description
Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘DEKYAZOO’.
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a cut flower and hereinafter referred to by the name ‘Dekyazoo’.
The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Hensbroek, The Netherlands. The objective of the breeding program is to create new freely-flowering cut Chrysanthemum plants with double inflorescences with quilled ray florets, strong flowering stems, short response time and excellent postproduction longevity.
The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Hensbroek, The Netherlands in March, 2009 of a proprietary selection of Chrysanthemum×morifolium identified as code number 05.43371.01, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 07.65782.01, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hensbroek, The Netherlands in November, 2009.
Asexual reproduction of the new Chrysanthemum plant by terminal cuttings in a controlled greenhouse environment in Hensbroek, The Netherlands since December, 2009 has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.
Plants of the new Chrysanthemum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Dekyazoo’. These characteristics in combination distinguish ‘Dekyazoo’ as a new and distinct Chrysanthemum plant:
-
- 1. Large decorative-type inflorescences with white-colored quilled ray florets.
- 2. Strong and upright flowering stems.
- 3. Short response time.
- 4. Uniform flowering habit.
- 5. Excellent postproduction longevity; plants maintain good substance for about three 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 flower two days earlier than plants of the female parent selection.
- 2. Plants of the new Chrysanthemum have larger inflorescences 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 flower two days earlier than plants of the male parent selection.
- 2. Plants of the new Chrysanthemum have larger inflorescences than plants of the male parent selection.
- 3. Plants of the new Chrysanthemum have decorative-type inflorescences whereas plants of the male parent selection have spider-type inflorescences.
- 4. Plants of the new Chrysanthemum and the male parent selection differ in ray floret color as plants of the male parent selection have yellow-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Anastasia’, disclosed in U.S. Plant Pat. No. 13,550. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of ‘Anastasia’ in the following characteristics:
-
- 1. Plants of the new Chrysanthemum had larger leaves than plants of ‘Anastasia’.
- 2. Plants of the new Chrysanthemum flowered about four days earlier than plants of ‘Anastasia’.
- 3. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Anastasia’.
- 4. Plants of the new Chrysanthemum had decorative-type inflorescences whereas plants of ‘Anastasia’ had spider-type inflorescences.
The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum plant 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 plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Dekyazoo’ grown as a spray-type.
The photograph on the second sheet comprises close-up views of the upper (top of the photograph) and lower surfaces (bottom of the photograph) of typical inflorescences and leaves of ‘Dekyazoo’.
The aforementioned photographs and following observations and measurements describe plants grown during the winter in ground beds in a glass-covered greenhouse in Hensbroek, The Netherlands and under commercial cut Chrysanthemum cultural practices. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels were about 7,000 lux. Plants were nine weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
