Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbel 0579’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; early and long flowering period; numerous single purple violet-colored flowers with darker purple coloration towards the throat; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNBEL 0579’.

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 0579’.

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 compact, mounding and freely branching Calibrachoa plants with numerous attractive and uniquely colored flowers.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in April, 2007 of a proprietary selection of Calibrachoa sp. identified as code number 9P9, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number 3137-1, 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 September, 2009.

Asexual reproduction of the new Calibrachoa plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since September, 2009 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 0579’. These characteristics in combination distinguish ‘Sunbel 0579’ as a new and distinct Calibrachoa plant:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching and flowering plant habit.
  • 4. Early and long flowering period.
  • 5. Numerous single purple violet-colored flowers with darker purple coloration towards the throat.
  • 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 primarily from plants of the female parent selection in flower color as plants of the female parent selection have pink-colored flowers. In addition, plants of the new Calibrachoa are more mounding than and not as upright as plants of the female parent selection.

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 red purple-colored flowers. In addition, plants of the new Calibrachoa have larger flowers than plants of the male parent selection.

Plants of the new Calibrachoa can also be compared to plants of Calibrachoa ‘Sunbelao’, disclosed in U.S. Plant Pat. No. 22,391. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Sunbelao’ differed primarily in the following characteristics:

• • 1. Plants of the new Calibrachoa were more compact and mounding than plants of ‘Sunbelao’.
  • 2. Plants of the new Calibrachoa had shorter internodes than plants of ‘Sunbelao’.
  • 3. Plants of the new Calibrachoa and ‘Sunbelao’ differed slightly in flower color.
