Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbelku 7372’, characterized by its upright to trailing plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; relatively large dark red-colored flowers; and good garden performance.

Description

Botanical designation: Calibrachoa sp.
Cultivar denomination: ‘SUNBELKU 7372’.
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 ‘Sunbelku 7372’.
The new Calibrachoa plant 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 trailing and freely branching Calibrachoa plants with numerous large and attractively colored flowers.
The new Calibrachoa plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in June, 2009 of a proprietary selection of Calibrachoa sp. identified as code number CR177-01, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number CR183-01, 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 Higashiomi, Shiga, Japan in July, 2010.
Asexual reproduction of the new Calibrachoa plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since July, 2010 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 ‘Sunbelku 7372’. These characteristics in combination distinguish ‘Sunbelku 7372’ as a new and distinct Calibrachoa plant:
    • 1. Upright to trailing plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Long flowering period.
    • 6. Relatively large dark red-colored flowers.
    • 7. Good garden performance.
Plants of 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 trailing than plants of the female parent selection. In addition, plants of the new Calibrachoa and the female parent selection differ slightly in flower color.
Plants of 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 male parent selection have orange red-colored flowers.
Plants of the new Calibrachoa can also be compared to plants of Calibrachoa ‘Suncalred’, disclosed in U.S. Plant Pat. No. 23,831. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Suncalred’ differed primarily in the following characteristics:
    • 1. Plants of the new Calibrachoa were broader than plants of ‘Suncalred’.
    • 2. Plants of the new Calibrachoa were more trailing than and not as upright as plants of ‘Suncalred’.
    • 3. Plants of the new Calibrachoa had longer internodes than plants of ‘Suncalred’.
    • 4. Plants of the new Calibrachoa had larger flowers than plants of ‘Suncalred’.
    • 5. Plants of the new Calibrachoa had shorter peduncles than plants of ‘Suncalred’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs 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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunbelku 7372’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunbelku 7372’.
 DETAILED BOTANICAL DESCRIPTION
