plant named ‘Duealkotisop’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Duealkotisop’, characterized by its compact, semi-upright to outwardly spreading to trailing and decumbent plant habit; freely branching habit; early and freely flowering habit; large light pink-colored flowers with dark red-colored centers; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘DUEALKOTISOP’.

BACKGROUND OF THE INVENTION

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

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 Calibrachoa plants with large attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor in July, 2009 in Rheinberg, Germany of a proprietary selection of Calibrachoa sp. identified as code number A08-2540-005, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number A06-2437-002, 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, 2012.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2012 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 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 ‘Duealkotisop’. These characteristics in combination distinguish ‘Duealkotisop’ as a new and distinct Calibrachoa plant:

• • 1. Compact, semi-upright to outwardly spreading to trailing and decumbent plant habit.
  • 2. Freely branching habit.
  • 3. Early and freely flowering habit.
  • 4. Large light pink-colored flowers with dark red-colored centers.
  • 5. 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 plant habit as plants of the new Calibrachoa are more compact than plants of the female parent selection. In addition, plants of the new Calibrachoa have darker pink-colored 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 flower color as plants of the new Calibrachoa have lighter pink-colored flowers than plants of the male parent selection.

Plants of the new Calibrachoa can be compared to plants of Calibrachoa sp. ‘Mini Famous Pink with Red Eye’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differed primarily from plants of ‘Mini Famous Pink with Red Eye’ in the following characteristics:

• • 1. Plants of the new Calibrachoa were shorter than plants of ‘Mini Famous Pink with Red Eye’.
  • 2. Plants of the new Calibrachoa were more freely branching than plants of ‘Mini Famous Pink with Red Eye’.
  • 3. Plants of the new Calibrachoa had longer internodes than plants of ‘Mini Famous Pink with Red Eye’.
  • 4. Plants of the new Calibrachoa had smaller leaves than plants of ‘Mini Famous Pink with Red Eye’.
  • 5. Plants of the new Calibrachoa and ‘Mini Famous Pink with Red Eye’ differed slightly in flower color.
  • 6. Plants of the new Calibrachoa had shorter peduncles than plants of ‘Mini Famous Pink with Red Eye’.

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 ‘Duealkotisop’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Rheinberg, Germany 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 plants were 13 weeks old when the photograph and description were taken.
