Description

Botanical designation: Calibrachoa parviflora.

Cultivar denomination: ‘DOCALRAIDRABER’.

BACKGROUND OF THE INVENTION

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

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely branching and early-flowering Calibrachoa plants with numerous large flowers with an interesting color pattern.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor in July 2022 in Rheinberg, Germany of a proprietary selection of Calibrachoa parviflora identified as code number AA22-K0152, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa parviflora identified as code number AA22-K0249, not patented, as the male, or pollen, parent. The new Calibrachoa 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 Rheinberg, Germany in April 2023.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since April 2023 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa 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 ‘Docalraidraber’. These characteristics in combination distinguish ‘Docalraidraber’ as a new and distinct Calibrachoa plant:

• • 1. Upright to outwardly spreading and mounding plant habit with plants eventually becoming trailing and decumbent.
  • 2. Vigorous growth habit and moderate growth rate.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Large flowers with purplish pink and deep red bi-colored petals yellowish-colored centers.
  • 6. Good container and garden performance.

The new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Calibrachoa are more vigorous than and not as compact as plants of the female parent selection.
  • 2. Plants of the new Calibrachoa are more freely branching than plants of the female parent selection.
  • 3. Plants of the new Calibrachoa are denser than and not as open as plants of the female parent selection.
  • 4. Plants of the new Calibrachoa have larger and more rounded flowers than plants of the female parent selection.
  • 5. Flowers of plants of the new Calibrachoa are purplish pink and deep red bi-colored petals yellowish-colored centers whereas flowers of plants of the female parent selection are light pink in color with darker pink-colored centers.

The new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Calibrachoa are more mounding and denser than and not as open as plants of the male parent selection.
  • 2. Plants of the new Calibrachoa are more freely branching than plants of the male parent selection.
  • 3. Plants of the new Calibrachoa have more rounded and flatter flowers than plants of the male parent selection.
  • 4. Flowers of plants of the new Calibrachoa are purplish pink and deep red bi-colored petals yellowish-colored centers whereas flowers of plants of the male parent selection are pink in color with yellow-colored centers.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa sp. ‘Ombre Pink’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘Ombre Pink’ in the following characteristics:

• • 1. Plants of the new Calibrachoa are larger than plants of ‘Ombre Pink’.
  • 2. Plants of the new Calibrachoa are more freely branching than plants of ‘Ombre Pink’.
  • 3. Plants of the new Calibrachoa are more freely flowering than plants of ‘Ombre Pink’.
  • 4. Plants of the new Calibrachoa have more rounded and flatter flowers than plants of ‘Ombre Pink’.
  • 5. Flowers of plants of the new Calibrachoa are purplish pink and deep red bi-colored petals yellowish-colored centers whereas flowers of plants of ‘Ombre Pink’ are soft pink in color with reddish-colored centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Calibrachoa 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 Calibrachoa plant. The photograph is a side perspective view of a typical flowering plant of ‘Docalraidraber’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the spring and summer in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were twelve weeks old when the photograph was taken and 25 weeks old when the detailed description was taken.
