Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbelapri’, characterized by its upright, outwardly spreading and mounding plant habit; dense and bushy form; vigorous growth habit; freely branching and flowering plant habit; long flowering period; apricot-colored flowers with red orange-colored centers and venation; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Sunbelapri’.

BACKGROUND OF THE INVENTION

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

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new uniform Calibrachoa cultivars with attractive and unique flower coloration.

The new Calibrachoa originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in April, 2003 of a proprietary selection of Calibrachoa sp. identified as code number R10, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number P6, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan.

Asexual reproduction of the new Calibrachoa by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since September, 2006, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Calibrachoa has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Sunbelapri’. These characteristics in combination distinguish ‘Sunbelapri’ as a new and distinct cultivar of Calibrachoa:

- 1. Upright, outwardly spreading and mounding plant habit; dense and bushy form.
- 2. Vigorous growth habit.
- 3. Freely branching and flowering plant habit.
- 4. Long flowering period.
- 5. Apricot-colored flowers with red orange-colored centers and venation.
- 6. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ 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 and the female parent selection differ in flower color as plants of the female parent selection have orange-colored flowers.

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

- 1. Plants of the new Calibrachoa have smaller flowers than plants of the male parent selection.
- 2. Plants of the new Calibrachoa and the male parent selection differ in flower color as plants of the male parent selection have light pink-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of ‘Sunbel-Apu’, disclosed in U.S. Plant Pat. No. 14,385. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Sunbel-Apu’ differed in the following characteristics:

- 1. Plants of the new Calibrachoa were shorter than plants of ‘Sunbel-Apu’.
- 2. Plants of the new Calibrachoa had larger flowers than plants of ‘Sunbel-Apu’.
- 3. Plants of the new Calibrachoa had longer peduncles than plants ‘Sunbel-Apu’.
- 4. Plants of the new Calibrachoa and ‘Sunbel-Apu’ differed in flower color as plants of ‘Sunbel-Apu’ had yellowish pink-colored flowers.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunbelapri’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers of ‘Sunbelapri’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Higashiomi, Shiga, Japan, under commercial practice during the late spring and early summer in a polyethylene-covered greenhouse.
