BACKGROUND OF THE INVENTION

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

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program is to create new container Dahlia plants that have a freely branching and flowering habit, strong leaves, large attractive inflorescences and good postproduction longevity and garden performance.

The new Dahlia plant originated from a cross-pollination during the autumn of 2018 in De Lier, The Netherlands of a proprietary selection of Dahlia variabilis identified as code number DA-0736, not patented, as the female, or seed, parent with a proprietary selection of Dahlia variabilis identified as code number DA-2014, not patented, as the male, or pollen, patent. The new Dahlia plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands during the summer of 2019.

Asexual reproduction of the new Dahlia plant by vegetative terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since the autumn of 2019 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 practices. 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 ‘Dodasumberebic’. These characteristics in combination distinguish ‘Dodasumberebic’ as a new and distinct Dahlia plant:

• • 1. Upright and uniformly mounding plant habit.
  • 2. Moderately vigorous growth habit and moderate growth rate.
  • 3. Freely branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Large single-type inflorescences with bright red and yellow bi-colored ray florets.
  • 7. Good postproduction longevity.
  • 8. Good garden performance and attractive to pollinators.

Compared to plants of the female parent selection, plants of the new Dahlia differ primarily in ray floret color as plants of the new Dahlia have bright red and yellow bi-colored ray florets whereas plants of the female parent selection have solid white-colored ray florets. In addition, plants of the new Dahlia have single-type inflorescences whereas plants of the female parent selection have double-type inflorescences.

Compared to plants of the male parent selection, plants of the new Dahlia differ primarily in ray floret color as plants of the new Dahlia have bright red and yellow bi-colored ray florets whereas plants of the male parent selection have solid light yellow-colored ray florets. In addition, plants of the new Dahlia have stronger garden performance than plants of the male parent selection.

Plants of the new Dahlia can be compared to plants of Dahlia variabilis ‘Dodasumbepubi’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Dahlia differ primarily from plants of ‘Dodasumbepubi’ in the following characteristics:

• • 1. Plants of the new Dahlia are smaller than plants of ‘Dodasumbepubi’.
  • 2. Plants of the new Dahlia have larger leaves than plants of ‘Dodasumbepubi’.
  • 3. Ray florets of plants of the new Dahlia are bright red and yellow bi-colored whereas ray florets of plants of ‘Dodasumbepubi’ are reddish purple and light yellow bi-colored.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates 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 photograph 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 is a side perspective view of a typical flowering plant of ‘Dodasumberebic’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and the following observations and measurements describe plants grown during the summer in 15-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under environmental conditions and cultural practices which approximate those generally used in commercial potted Dahlia production. During the production of the plants, day temperatures ranged from 18° C. to 30° C., night temperatures ranged from 16° C. to 22° C. and light levels were at least 135 watt/m². Plants were pinched one time about four weeks after sticking unrooted cuttings. Plants were twelve weeks old when the photograph was taken and eleven weeks old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
