Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Dekpaddy’, characterized by its pompon-type inflorescences with light green-colored ray florets; strong and upright flowering stems; uniform and freely flowering habit; and excellent postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘DEKPADDY’.

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 ‘Dekpaddy’.

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 pompon-type Chrysanthemum plants with attractive ray floret coloration and excellent postproduction longevity.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Hensbroek, The Netherlands on May 10, 2007 of a proprietary selection of Chrysanthemum×morifolium identified as code number 49395, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 04.42289.03, not patented. 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 December, 2007.

Asexual reproduction of the new Chrysanthemum plant by terminal cuttings in a controlled greenhouse environment in Hensbroek, The Netherlands since January, 2008, 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 ‘Dekpaddy’. These characteristics in combination distinguish ‘Dekpaddy’ as a new and distinct Chrysanthemum plant:

- 1. Pompon-type inflorescences with light green-colored ray florets.
- 2. Strong and upright flowering stems.
- 3. Uniform and freely flowering habit.
- 4. Excellent postproduction longevity; plants maintain good substance for about 21 days 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 about three days later than plants of the female parent selection.
- 2. Plants of the new Chrysanthemum and the female parent selection differ in ray floret color as plants of the female parent selection have lighter green-colored ray florets.

Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Chrysanthemum flower about two days later than plants of the male parent selection.
- 2. Plants of the new Chrysanthemum and the male parent selection differ in ray floret color as plants of the male parent selection have lighter green-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Dekkicker’, disclosed in U.S. Plant Pat. No. 20,052. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of ‘Dekkicker’ in the following characteristics:

- 1. Plants of the new Chrysanthemum were less vigorous than plants of ‘Dekkicker’.
- 2. Plants of the new Chrysanthemum had darker green-colored leaves than plants of ‘Dekkicker’.
- 3. Plants of the new Chrysanthemum and ‘Dekkicker’ differed in ray floret color as plants of ‘Dekkicker’ had more yellow-colored ray florets.

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 ‘Dekpaddy’ 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 ‘Dekpaddy’.

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 8.5 weeks old when the description was taken and 9.5 weeks old when the photographs 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.
