Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbel 208’, characterized by its mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; relatively large bright purple violet-colored flowers; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNBEL 208’.

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 ‘Sunbel 208’.

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 attractively colored flowers.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in October, 2009 of a proprietary selection of Calibrachoa sp. identified as code number T590-1, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number 7161-3, 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 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 ‘Sunbel 208’. These characteristics in combination distinguish ‘Sunbel 208’ as a new and distinct Calibrachoa plant:

• • 1. Mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Long flowering period.
  • 6. Relatively bright purple violet-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 the following characteristics:

• • 1. Plants of the new Calibrachoa are smaller than plants of the female parent selection.
  • 2. Plants of the new Calibrachoa and the female parent differ in flower color as plants of the female parent selection have deep blue-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 the following characteristics:

• • 1. Plants of the new Calibrachoa are smaller 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 Calibrachoa ‘Suncalsifobu’, disclosed in U.S. Plant Pat. No. 20,659. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Suncalsifobu’ differed primarily in the following characteristics:

• • 1. Plants of the new Calibrachoa were taller than plants of ‘Suncalsifobu’.
  • 2. Plants of the new Calibrachoa had longer internodes than plants of ‘Suncalsifobu’.
  • 3. Plants of the new Calibrachoa were more freely flowering than plants of ‘Suncalsifobu’.
  • 4. Plants of the new Calibrachoa had smaller flowers than plants of ‘Suncalsifobu’.
  • 5. Flowers of plants of the new Calibrachoa were darker in color than flowers of plants of ‘Suncalsifobu’.
