STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT AND ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee of the instant application, Beekenkamp Plants B.V. of Maasdijk, The Netherlands on Oct. 20, 2020, application number 2020/2575. Foreign priority is not claimed to this European Community Plant Breeder's Rights application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida and hereinafter referred to by the name ‘BKDAMAGFCY’.

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program is to create new vigorous container Dahlia plants with large inflorescences with attractive ray floret coloration.

The new Dahlia plant originated from a cross-pollination in September, 2015 in Hillegom, The Netherlands of a proprietary selection of Dahlia hybrida identified as code number FET.S14.012.007, not patented, as the female, or seed, parent with a proprietary selection of Dahlia hybrida identified as code number FET.S13.024.013, not patented, as the male, or pollen, parent. The new Dahlia 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 Hillegom, The Netherlands in September, 2016.

Asexual reproduction of the new Dahlia plant by terminal cuttings in a controlled greenhouse environment in Hillegom, The Netherlands since March, 2017 has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possible combinations of environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘BKDAMAGFCY’. These characteristics in combination distinguish ‘BKDAMAGFCY’ as a new and distinct Dahlia plant:

- 1. Upright to somewhat outwardly spreading and sturdy plant habit.
- 2. Vigorous growth habit.
- 3. Freely basal branching habit; dense and bushy growth habit.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit.
- 6. Large, decorative type inflorescences with bright yellow-colored ray florets.
- 7. Good garden performance.

Plants of the new Dahlia differ primarily from plants of the female parent selection in inflorescence type as plants of the new Dahlia have decorative type inflorescences whereas plants of the female parent selection have single type inflorescences. In addition, leaves of plants of the new Dahlia are darker green in color than leaves of plants of the female parent selection.

Plants of the new Dahlia differ primarily from plants of the male parent selection in plant size as plants of the new Dahlia are larger than plants of the male parent selection. In addition, ray florets of plants of the new Dahlia are bright yellow in color whereas ray florets of plants of the male parent selection are pale yellow in color.

Plants of the new Dahlia can also be compared to plants of Dahlia hybrida ‘BKDAMAGYL’, disclosed in U.S. Plant Pat. No. 31,240. In side-by-side comparisons, plants of the new Dahlia differ from plants of ‘BKDAMAGYL’ in the following characteristics:

- 1. Plants of the new Dahlia have darker green-colored leaves than plants of ‘BKDAMAGYL’.
- 2. Plants of the new Dahlia have smaller inflorescences than plants of ‘BKDAMAGYL’.

Plants of the new Dahlia can also be compared to plants of Dahlia hybrida ‘XXL Aztec Hidalgo’, not patented. In side-by-side comparisons, plants of the new Dahlia differ from plants of ‘XXL Aztec Hidalgo’ in the following characteristics:

- 1. Plants of the new Dahlia have darker green-colored leaves than plants of ‘XXL Aztec Hidalgo’.
- 2. Plants of the new Dahlia have slightly smaller inflorescences than plants of ‘XXL Aztec Hildalgo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Dahlia 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 Dahlia plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘BKDAMAGFCY’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical inflorescence of ‘BKDAMAGFCY’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and the following observations and measurements describe plants grown during the late winter and early spring in 20-cm containers in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial Dahlia production. During the production of the plants, day and night temperatures ranged from 17° C. to 19° C. Plants were pinched one time and were eleven weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
