Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Dektoshka Red’, characterized by its large daisy-type inflorescences with dark red-colored ray florets; strong, thick and upright flowering stems; uniform flowering habit; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘DEKTOSHKA RED’.

BACKGROUND OF THE INVENTION

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 ‘Dektoshka Red’.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘Dektoshka’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Dektoshka’ in a controlled greenhouse environment in Hensbroek, The Netherlands in September, 2007.

Asexual reproduction of the new Chrysanthemum plant by terminal cuttings in a controlled greenhouse environment in Hensbroek, The Netherlands since October, 2007, has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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 ‘Dektoshka Red’. These characteristics in combination distinguish ‘Dektoshka Red’ as a new and distinct Chrysanthemum plant:

- 1. Large daisy-type inflorescences with dark red-colored ray florets.
- 2. Strong, thick and upright flowering stems.
- 3. Uniform flowering habit.
- 4. Good postproduction longevity; plants maintain good substance for about 20 days in an interior environment.

Plants of the new Chrysanthemum differ from plants of the parent, ‘Dektoshka’ primarily in ray floret color as plants of ‘Dektoshka’ have red purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Timman Yellow’, not patented. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of ‘Timman Yellow’ in the following characteristics:

- 1. Plants of the new Chrysanthemum were less vigorous than plants of ‘Timman Yellow’.
- 2. Plants of the new Chrysanthemum flowered about two days later than plants of ‘Timman Yellow’.
- 3. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Timman Yellow’.
- 4. Plants of the new Chrysanthemum and ‘Timman Yellow’ differed in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum plant. 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 plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Dektoshka Red’ 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 ‘Dektoshka Red’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter in Hensbroek, The Netherlands, under commercial practice in ground beds in a glass-covered greenhouse. Plants were initially given 1.5 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 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.
