Abstract
A new and distinct cultivar of Chrysanthemum plant named ‘Dekringa Yellow’, characterized by its single-type inflorescences with bright yellow-colored ray florets; strong and upright flowering stems; moderately vigorous growth habit; freely flowering habit; early and uniform flowering response; and good postproduction longevity.
Description
Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘Dekringa Yellow’.
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 ‘Dekringa Yellow’.
The new Chrysanthemum is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘Dekringabronze’, disclosed in U.S. Plant Pat. No. 19,344. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Dekringabronze’ in a controlled greenhouse environment in Hensbroek, The Netherlands in October, 2006.
Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled greenhouse environment in Hensbroek, The Netherlands since November, 2006, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
Plants of the new Chrysanthemum 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 ‘Dekringa Yellow’. These characteristics in combination distinguish ‘Dekringa Yellow’ as a new and distinct cultivar of Chrysanthemum:
-
- 1. Single-type inflorescences with bright yellow-colored ray florets.
- 2. Strong and upright flowering stems.
- 3. Moderately vigorous growth habit.
- 4. Freely flowering habit.
- 5. Early and uniform flowering response; plants flower about 37 days after the start of photoinductive treatments.
- 6. Good postproduction longevity; plants maintain good substance for about four weeks in an interior environment.
Plants of the new Chrysanthemum differ from plants of ‘Dekringabronze’ primarily in ray floret color as plants of ‘Dekringabronze’ have bronze-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Dektanga Pink’, disclosed in U.S. Plant Pat. No. 18,903. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of ‘Dektanga Pink’ in the following characteristics:
-
- 1. Plants of the new Chrysanthemum were more vigorous than plants of ‘Dektanga Pink’.
- 2. Plants of the new Chrysanthemum were more freely branching than plants of ‘Dektanga Pink’.
- 3. Plants of the new Chrysanthemum and ‘Dektanga Pink’ differed in ray floret color as plants of ‘Dektanga Pink’ had pink-colored ray florets.
- 4. Plants of the new Chrysanthemum had larger ray florets than plants of ‘Dektanga Pink’.
The accompanying colored 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 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 ‘Dekringa Yellow’ grown as a spray type.
The photograph on the second sheet comprises close-up views of the upper (top of photograph) and lower surfaces (bottom of photograph) of typical inflorescences and leaves of ‘Dekringa Yellow’.
The aforementioned photographs and following observations and measurements describe plants grown during the late summer in Hensbroek, The Netherlands, under commercial practice in a glass-covered greenhouse. Plants were initially given two weeks of 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 kilolux. Plants were pinched one time and were 7.5 weeks from planting when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
