Calibrachoa plant named ‘Sunbelrikist’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbelrikist’, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; long flowering period; and red purple and yellow variegated flowers.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Sunbelrikist’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Sunbelrikist’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Shiga, Japan. The objective of the breeding program is to create new Calibrachoa cultivars with attractive foliage and flower coloration.

The new Calibrachoa originated from a cross-pollination made by the Inventor in April, 2002 in Shiga, Japan of a proprietary selection of Calibrachoa sp. identified as code number 20, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number 28, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Shiga, Japan.

Asexual reproduction of the new Calibrachoa by terminal cuttings in a controlled environment in Shiga, Japan since September, 2004, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunbelrikist has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Sunbelrikist’. These characteristics in combination distinguish ‘Sunbelrikist’ as a new and distinct cultivar of Calibrachoa:

• • 1. Upright, outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching and flowering plant habit.
  • 4. Long flowering period.
  • 5. Red purple and yellow variegated flowers.

Plants of the new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Calibrachoa have larger flowers than plants of the female parent selection.
  • 2. Plants of the new Calibrachoa and the female parent selection differ in flower color as plants of the female parent selection have red-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 color as plants of the male parent selection have white-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the cultivar Sunbelfire, disclosed in U.S. Plant Pat. No. 16,684. In side-by-side comparisons conducted in Shiga, Japan, plants of the new Calibrachoa and the cultivar Sunbelfire differed in the following characteristics:

• • 1. Plants of the new Calibrachoa were more taller than but not as broad as plants of the cultivar Sunbelfire.
  • 2. Plants of the new Calibrachoa had broader leaves than plants of the cultivar Sunbelfire.
  • 3. Plants of the new Calibrachoa had larger flowers than plants of the cultivar Sunbelfire.
  • 4. Plants of the new Calibrachoa and the cultivar Sunbelfire differed in flower color as plants of the cultivar Sunbelfire had yellow and red variegated flowers.
  • 5. Plants of the new Calibrachoa had shorter peduncles than plants of the cultivar Sunbelfire.
