Abstract

A new and distinct Calibrachoa plant named ‘USCAL51505’, characterized by its compact, upright to outwardly spreading and mounding to trailing plant habit; moderately vigorous growth habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; double flowers with pale yellow-colored petals and petaloids; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL51505’.

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 ‘USCAL51505’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new uniform and freely-branching Calibrachoa plants with unique and attractive flower forms and colors and good garden performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan on May 26, 2012 of a proprietary seedling selection of Calibrachoa sp. identified as code number CJ08-07, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number CC016-01, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and first selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bonsall, Calif. on Jun. 5, 2013.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, Calif. since Jun. 6, 2013 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 ‘USCAL51505’. These characteristics in combination distinguish ‘USCAL51505’ as a new and distinct Calibrachoa plant:

- 1. Compact, upright to outwardly spreading and mounding to trailing plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit; dense and bushy appearance.
- 4. Early and freely flowering habit.
- 5. Double flowers with pale yellow-colored petals and petaloids.
- 6. Good garden performance.

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 mounding than and not as upright as plants of the female parent selection.
- 2. Plants of the new Calibrachoa and the female parent selection differ in flower color as flowers of plants of the female parent selection are lighter yellow in color.

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 than and not as creeping as plants of the male parent selection.
- 2. Plants of the new Calibrachoa have double-type flowers whereas plants of the male parent selection have single-type flowers.
- 3. Plants of the new Calibrachoa and the male parent selection differ in flower color as flowers of plants of the male parent selection are darker yellow in color.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘KLECA15290’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘KLECA15290’ in the following characteristics:

- 1. Plants of the new Calibrachoa are more vigorous than plants of ‘KLECA15290’.
- 2. Plants of the new Calibrachoa have fully double flowers whereas plants of ‘KLECA15290’ have semi-double flowers.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa sp. ‘KLECA11226’, not patented. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘KLECA11226’ in the following characteristics:

- 1. Plants of the new Calibrachoa have fully double flowers whereas plants of ‘KLECA11226’ have semi-double flowers.
- 2. Plants of the new Calibrachoa and ‘KLECA11226’ differ in flower color as flowers of plants of ‘KLECA11226’ are yellow and rose pink in color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late winter and early spring in 11.5-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Calibrachoa production.
