Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Bkgardyl’, characterized by its compact, upright and mounded plant habit; moderately vigorous growth habit; uniform flowering response; early and freely flowering habit; decorative-type inflorescences with bright yellow-colored ray florets; and good garden performance.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘BKGARDYL’.

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 garden Chrysanthemum plant and hereinafter referred to by the name ‘Bkgardyl’.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium ‘Bkgardrs’, not patented. The new Chrysanthemum plant was discovered by the Inventor in September, 2012 as a single flowering plant from within a population of plants of ‘Bkgardrs’ in a controlled greenhouse environment in Monster, The Netherlands.

Asexual reproduction of the new Chrysanthemum plant by vegetative tip cuttings was first conducted in Maasdijk, The Netherlands in December, 2012. Asexual reproduction by cuttings 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 combinations of 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 ‘Bkgardyl’. These characteristics in combination distinguish ‘Bkgardyl’ as a new and distinct garden Chrysanthemum plant:

- 1. Compact, upright and mounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Uniform flowering response.
- 4. Early and freely flowering habit.
- 5. Decorative-type inflorescences with bright yellow-colored ray florets.
- 6. Good garden performance.

Plants of the new Chrysanthemum differ from plants of the parent, ‘Bkgardrs’, primarily in ray floret coloration as plants of the new Chrysanthemum have bright yellow-colored ray florets whereas plants of ‘Bkgardrs’ have pink-colored ray florets.

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

- 1. Plants of the new Chrysanthemum were denser and bushier than plants of ‘Queenstown Yellow’.
- 2. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Queenstown Yellow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying 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 typical flowering plant of ‘Bkgardyl’ grown in a container.

The photograph on the second sheet is a close-up view of the upper (top of sheet) and lower (bottom of sheet) surfaces of typical inflorescences and leaves of ‘Bkgardyl’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 12-cm containers during the winter in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial garden Chrysanthemum production. During the production of the plants, day and night temperatures ranged from about 18° C. to 19° C. and light levels averaged 7,000 lux. Plants were grown under photoinductive short day/long night treatments, pinched one time and were 68 days old when the photographs and 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.
