Calibrachoa plant named ‘Balcabred’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Balcabred’ characterized by its dark red-colored flowers, medium green-colored foliage, good basal branching character, and moderately vigorous, mounded-trailing growth habit.

Description

Latin name of genus and species of plant claimed: Calibrachoa×hybrida.

Variety denomination: ‘Balcabred’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant botanically known as Calibrachoa×hybrida and hereinafter referred to by the cultivar name ‘Balcabred’.

The new cultivar originated in a controlled breeding program in Elburn, Ill. during September 2002. The objective of the breeding program was the development of Calibrachoa cultivars with attractive flower coloration, medium green-colored foliage, and moderately vigorous, mounded-trailing growth habit.

The female (seed) parent of the new cultivar was the proprietary Calibrachoa×hybrida breeding selection designated 2043-2, not patented, characterized by its scarlet red-colored flowers and semi-upright growth habit. The male (pollen) parent of the new cultivar was the proprietary Calibrachoa×hybrida breeding selection designated 1032-2, not patented, characterized by its cherry red-colored flowers and semi-upright growth habit. The new Calibrachoa was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination during May 2003 in a controlled environment at Elburn, Ill.

Asexual reproduction of the new cultivar by terminal stem cuttings since May 2003 at Elburn, Ill. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcabred’ as a new and distinct cultivar of Calibrachoa plant:

• • 1. Dark red-colored flowers;
  • 2. Medium green-colored foliage;
  • 3. Good basal branching character; and
  • 4. Moderately vigorous, mounded-trailing growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and growth habit and from plants of the male parent primarily in flower color and growth habit.

Of the many commercially available Calibrachoa cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Sunbelre’, U.S. Plant Pat. No. 14,756. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Sunbelre’ in the following characteristics:

• • 1. Plants of the new cultivar have smaller leaves than plants of ‘Sunbelre’;
  • 2. Plants of the new cultivar are more compact than plants of ‘Sunbelre’; and
  • 3. Plants of the new cultivar have a flower color different from plants of ‘Sunbelre’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcabred’. The plants were grown in 10 cm pots for 11 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balcabred’.

FIG. 2 illustrates a close-up view of individual flowers of ‘Balcabred’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on May 31, 2005 between 3:00 p.m. and 4:00 p.m. under natural light conditions, in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 10 cm pots for 11 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 75° F. (21° C. to 24° C.) during the day and approximately 50° F. to 58° F. (10° C. to 14° C.) during the night. Greenhouse light levels of 5,000 to 8,000 footcandles were maintained during the day.
