Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Suncal 1231’, characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; reddish orange-colored flowers; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNCAL 1231’.

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 ‘Suncal 1231’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new mounding and freely branching Calibrachoa plants with numerous large and attractive flowers with unique coloration.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in September, 2013 of a proprietary selection of Calibrachoa sp. identified as code number C80, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number C65, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2014.

Asexual reproduction of the new Calibrachoa plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since March, 2016 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 ‘Suncal 1231’. These characteristics in combination distinguish ‘Suncal 1231’ as a new and distinct Calibrachoa plant:

• • 1. Upright to outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Reddish orange-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 flower color as plants of the female parent selection have darker orange-colored flowers.

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 center color as flowers of plants of the male parent selection have darker orange-colored flower centers.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa sp. ‘Suncalore’, disclosed in U.S. Plant patent application Ser. No. 12/804,918 (abandoned). In side-by-side comparisons, plants of the new Calibrachoa and ‘Suncalore’ differ primarily in the following characteristics:

• • 1. Plants of the new Calibrachoa taller and broader than plants of ‘Suncalore’.
  • 2. Plants of the new Calibrachoa have smaller leaves than plants of ‘Suncalore’.
  • 3. Plants of the new Calibrachoa have smaller flowers than plants of ‘Suncalore’.
  • 4. Flower centers of plants of the new Calibrachoa are lighter reddish orange in color than flower centers of plants of ‘Suncalore’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 24-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day temperatures averaged 23C and night temperatures averaged 13C. Plants were four months old when the photographs and the description were taken.
