Abstract
A new and distinct cultivar of Dahlia plant named ‘BKDAMAGRB’, characterized by its broadly upright plant habit; moderate basal branching habit; dense and bushy growth habit; large dark green-colored leaves; and large decorative type inflorescences with white and red purple bi-colored ray florets.
Description
Botanical designation: Dahlia hybrida.
Cultivar denomination: ‘BKDAMAGRB’.
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 ‘BKDAMAGRB’.
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 large container Dahlia plants with large and attractive decorative type inflorescences.
The new Dahlia plant originated from a cross-pollination in September, 2013 in Hillegom, The Netherlands of a proprietary selection of Dahlia hybrida identified as code number FET.S12.011.003, not patented, as the female, or seed, parent with a proprietary selection of Dahlia hybrida identified as code number FET.S12.003.021, 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 October, 2015.
Asexual reproduction of the new Dahlia plant by vegetative terminal cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since February, 2016 has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.
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 ‘BKDAMAGRB’. These characteristics in combination distinguish ‘BKDAMAGRB’ as a new and distinct Dahlia plant:
-
- 1. Broadly upright plant habit.
- 2. Moderate basal branching habit; dense and bushy growth habit.
- 3. Large dark green-colored leaves.
- 4. Large decorative type inflorescences with white and red purple bi-colored ray florets.
Plants of the new Dahlia differ primarily from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Dahlia have decorative type inflorescences whereas plants of the female parent selection have cactus type inflorescences.
- 2. Ray floret colors of plants of the new Dahlia are brighter and more vivid than ray floret colors of plants of the female parent selection.
Plants of the new Dahlia differ primarily from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Dahlia have decorative type inflorescences whereas plants of the male parent selection have semi-cactus type inflorescences.
- 2. Ray florets of plants of the new Dahlia are white and red purple in color whereas ray floret of plants of the male parent selection are pink in color.
Plants of the new Dahlia can be compared to plants of Dahlia hybrida ‘XXL Veracruz’, not patented. In side-by-side comparisons, plants of the new Dahlia differ from plants of ‘XXL Veracruz’ in the following characteristics:
-
- 1. Plants of the new Dahlia are more upright and taller than plants of ‘XXL Veracruz’.
- 2. Plants of the new Dahlia and ‘XXL Veracruz’ differ in ray floret color as plants of ‘XXL Veracruz’ have light pink and violet bi-colored ray florets.
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 comprises a side perspective view of a typical flowering plant of ‘BKDAMAGRB’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘BKDAMAGRB’.
The aforementioned photographs and the following observations and measurements describe plants grown during the winter in 19-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 nine weeks old when the photographs and description were taken. To induce inflorescence initiation and development, plants were grown under short nyctoperiod (long day) conditions. 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.
