Abstract

A new and distinct Petunia plant named ‘MIYOPEGB60-1’, characterized by its upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; yellow-colored flowers; and good garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘MIYOPEGB60-1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia X hybrida and hereinafter referred to by the name ‘MIYOPEGB60-1’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Nagaizumicho, Shizuoka, Japan. The objective of the breeding program is to create new vigorous and freely-branching and uniformly mounding Petunia plants with yellow-colored flowers and good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventors in August, 2014 in Nagaizumicho, Shizuoka, Japan of an unnamed proprietary selection of Petunia X hybrida, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number P26-349-1, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Nagaizumicho, Shizuoka, Japan in July, 2015.

Asexual reproduction of the new Petunia plant by in vitro meristem culture in a controlled greenhouse environment in Nagaizumicho, Shizuoka, Japan since April, 2016 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of 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 ‘MIYOPEGB60-1’. These characteristics in combination distinguish ‘MIYOPEGB60-1’ as a new and distinct Petunia plant:

- 1. Upright to outwardly spreading and mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit.
- 4. Early and freely flowering habit.
- 5. Yellow-colored flowers.
- 6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of the female parent selection in flower color as flowers of plants of the new Petunia are darker and more intense yellow in color than flowers of plants of the female parent selection. In addition, flowers of plants of the new Petunia are more funnelform in shape than and not as salverform in shape as plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of the male parent selection in flower size as plants of the new Petunia have larger flowers than plants of the male parent selection.

Plants of the new Petunia can be compared to plants of ‘Shockwave Yellow’, not patented. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Shockwave Yellow’ in the following characteristics:

- 1. Plants of the new Petunia are more vigorous than plants of ‘Shockwave Yellow’.
- 2. Leaves of plants of the new Petunia are broader than leaves of plants of ‘Shockwave Yellow’.
- 3. Flowers of plants of the new Petunia are darker and more intense yellow in color than flowers of plants of ‘Shockwave Yellow’.

Plants of the new Petunia can also be compared to plants of ‘Horizon Yellow’, not patented. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Horizon Yellow’ in the following characteristics:

- 1. Plants of the new Petunia are smaller than plants of ‘Horizon Yellow’.
- 2. Plants of the new Petunia are more vigorous than plants of ‘Horizon Yellow’.
- 3. Plants of the new Petunia have smaller flowers than plants of ‘Horizon Yellow’.
- 4. Flowers of plants of the new Petunia are darker and more intense yellow in color than flowers of plants of ‘Horizon Yellow’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring and summer in 12-cm containers in a polyethylene-covered greenhouse in Fukuroishi, Shizuoka, Japan and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 23° C., night temperatures averaged 10° C. and light levels averaged 80,000 lux. Plants were seven weeks from planting rooted cuttings when the photographs and description were taken.
