plant named ‘Docalvolne’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Docalvolne’, characterized by its semi-upright to outwardly spreading, trailing and decumbent plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; flowers with light red to light red purple and light yellow bi-colored petals; and good garden performance.

Description

Botanical designation: Calibrachoa X hybrida.

Cultivar denomination: ‘DOCALVOLNE’.

BACKGROUND OF THE INVENTION

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

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 compact and early-flowering and vigorous Calibrachoa plants with large attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor in July, 2013 in Rheinberg, Germany of a proprietary selection of Calibrachoa X hybrida identified as code number AA11-003133-001, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa X hybrida identified as code number AA12-003454-005, 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 May, 2017.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2017 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 ‘Docalvolne’. These characteristics in combination distinguish ‘Docalvolne’ as a new and distinct Calibrachoa plant:

• • 1. Semi-upright to outwardly spreading, trailing and decumbent plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Flowers with light red to light red purple and light yellow bi-colored petals.
  • 6. Good 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 compact than plants of the female parent selection.
  • 2. Plants of the new Calibrachoa flower earlier than plants of the female parent selection.
  • 3. Plants of the new Calibrachoa have larger flowers than plants of the female parent selection.

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 flower earlier than plants of the male parent selection.
  • 2. Plants of the new Calibrachoa are not as freely flowering as plants of the male parent selection.

Plants of the new Calibrachoa can be compared to plants of Calibrachoa sp. ‘Cal Paicoras’, disclosed in U.S. Plant Pat. No. 19,256. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘Cal Paicoras’ in the following characteristics:

• • 1. Plants of the new Calibrachoa are more compact than plants of ‘Cal Paicoras’.
  • 2. Plants of the new Calibrachoa flower earlier than plants of ‘Cal Paicoras’.
  • 3. Plants of the new Calibrachoa have larger flowers than plants of ‘Cal Paicoras’.
  • 4. Plants of the new Calibrachoa and ‘Cal Paicoras’ differ in flower color as plants of ‘Cal Paicoras’ have coral and light pink bi-colored flowers.

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 ‘Docalvolne’ 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. Rooted young plants were pinched one time three weeks after planting and were 16 weeks old when the photograph and description were taken.
