Abstract

A new and distinct cultivar of Petunia plant named ‘Balsundarco’, characterized by its single type, dark coral-colored flowers, dark green-colored foliage, and moderately vigorous, mounded -trailing growth habit.

Description

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

Variety denomination: ‘Balsundarco’.

BACKGROUND OF THE INVENTION

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

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during February 2004. The objective of the breeding program was the development of Petunia cultivars with single type flowers, unique flower coloration, and a vigorous, mounded-trailing growth habit.

The new Petunia cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Petunia×hybrida breeding selection designated 1694-1, not patented, characterized by its single type, scarlet red-colored flowers, dark green-colored foliage, and well-branched, trailing growth habit. The male (pollen) parent of the new cultivar is the proprietary Petunia×hybrida breeding selection designated SA2091-1, not patented, characterized by its single type, medium coral-colored flowers, medium green-colored foliage, and trailing growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during October 2004 in a controlled environment at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since October 2004 at Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the 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 ‘Balsundarco’ as a new and distinct cultivar of Petunia plant:

- 1. Single type, dark coral-colored flowers;
- 2. Dark green-colored foliage; and
- 3. 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, foliage color, and growth habit.

Of the many commercially available Petunia cultivars known to the inventor, the most similar in comparison to the new cultivar is Suncatcher™ Coral Prism ‘Balsuncora’, U.S. Plant Pat. No. 16,731. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Balsuncora’ in the following characteristics:

- 1. Plants of the new cultivar have a petal color different from plants of ‘Balsuncora’; and
- 2. Plants of the new cultivar have a corolla tube color different from plants of ‘Balsuncora’.

In addition, plants of the new cultivar are similar in comparison to Suncatcher™ Salmon Vein ‘Kersamfan’, U.S. Plant Pat. No. 18,128. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Kersamfan’ in the following characteristics:

- 1. Plants of the new cultivar lack venation and have a petal color different from plants of ‘Kersamfan’; and
- 2. Plants of the new cultivar are taller than plants of ‘Kersamfan’.

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 ‘Balsundarco’. The plants were grown in 4.5 inch pots for 9 weeks in a greenhouse at West Chicago, Ill.

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

FIG. 2 illustrates a close-up view of an individual flower of ‘Balsundarco’.

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 Feb. 2, 2006 between 9:00 a.m. and 11:00 a.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 glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 4.5 inch pots for 9 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day.
