Latin name of genus and species of plant claimed: Petchoa, Petunia-Calibrachoa intergeneric hybrid.
Variety denomination: ‘Balpetcel145’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petchoa plant botanically known as Petchoa, Petunia-Calibrachoa intergeneric hybrid and hereinafter referred to by the cultivar name ‘Balpetcel145’.
The new cultivar originated in a controlled breeding program in Guadalupe, California during March 2020. The objective of the breeding program was the development of Petchoa cultivars that have dark yellow-colored flowers and a mounded-trailing growth habit.
The new Petchoa cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Petchoa breeding selection coded 20-153-1, not patented, characterized by its single-type, light yellow-colored flowers, medium green-colored foliage, and moderately vigorous, mounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Petchoa breeding selection coded 20-184-1, not patented, characterized by its single-type, dark yellow-colored flowers, medium green-colored foliage, low growth vigor, and mounded growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated cross-pollination during September 2020 in a controlled environment in Guadalupe, California.
Asexual reproduction of the new cultivar by terminal stem cuttings since September 2020 in Guadalupe, California and West Chicago, Illinois 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 ‘Balpetcel145’ as a new and distinct cultivar of Petchoa plant:
- 1. Dark yellow-colored flowers;
- 2. Medium 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 having darker yellow-colored flowers. Plants of the new cultivar differ from plants of the male parent primarily in having more branches per plant and increased growth vigor.
Of the many commercially available Petchoa cultivars, the most similar in comparison to the new cultivar is Bee's Knees ‘Balcobees’, U.S. Plant Pat. No. 32,448. However, in comparison, plants of the new cultivar differ from plants of ‘Balcobees’ in at least the following characteristics:
- 1. Plants of the new cultivar have darker yellow-colored flowers than plants of ‘Balcobees’;
- 2. Plants of the new cultivar have a more mounded growth habit than plants of ‘Balcobees’; and
- 3. Plants of the new cultivar have larger diameter corollas than plants of ‘Balcobees’.
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 may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balpetcel145’. The approximately 4-month-old plants were grown in 12-inch hanging baskets for approximately 8 weeks in an outdoor nursery in West Chicago, Ill. Treatments are described below in the Detailed Botanical Description.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balpetcel145’.
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, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in August 2023 under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe approximately 4-month-old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in 12-inch hanging baskets utilizing a soilless growth medium for approximately 8 weeks in an outdoor nursery in West Chicago, Ill. Plants were given three pinches prior to transplant. Eight weeks after cuttings were stuck, plants were sprayed with growth regulators B-NINE (daminozide[butanedioic acid mono (2,2-dimethylhydrazide)]) at 2,500 ppm and CYCOCEL (chlormequat (2-chloroethyl)trimethylammonium chloride) at 800 ppm. Prior to transplant plants were grown in a polycarbonate greenhouse in West Chicago, Ill. Greenhouse temperatures were maintained at approximately 75° F. to 80° F. (24° C. to 27° C.) during the day and approximately 65° F. to 70° F. (18° C. to 21° C.) during the night. Supplemental lighting was used during propagation stage. Measurements and numerical values represent averages of typical plants.
