Abstract

A new and distinct cultivar of Petunia plant named ‘Keipemokohos’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; relatively small and deeply-lobed flowers that are purplish pink in color with white-colored throats; and good garden performance.

Description

Botanical designation: Petunia x hybrida.

Cultivar denomination: ‘KEIPEMOKOHOS’.

A Japanese Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Keisei Rose Nurseries Inc. of Yachiyo, Chiba, Japan on Aug. 10, 2023, application number 36977. Foreign priority is not claimed to this application.

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 ‘Keipemokohos’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Katori, Chiba, Japan. The objective of the breeding program is to create new compact and early-flowering Petunia plants with numerous attractive flowers.

The new Petunia plant originated from a cross-pollination made by the Inventors in May, 2017 in Katori, Chiba, Japan of an unnamed proprietary selection of Petunia x hybrida, not patented, as the female, or seed, parent with an unnamed proprietary selection of Petunia x hybrida, 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 Katori, Chiba, Japan in November, 2017.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Katori, Chiba, Japan since November, 2017 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 conditions. 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 ‘Keipemokohos’. These characteristics in combination distinguish ‘Keipemokohos’ as a new and distinct Petunia plant:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Relatively small and deeply-lobed flowers that are purplish pink in color with white-colored throats.
  • 7. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. 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 purplish pink in color with white-colored throats whereas flowers of plants of the female parent selection are pink in color with brownish-colored venation. In addition, plants of the new Petunia are more freely flowering than plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in flower color as flowers of plants of the new Petunia are purplish pink in color with white-colored throats whereas flowers of plants of the male parent selection are light pink in color. In addition, plants of the new Petunia are more freely flowering than plants of the male parent selection.

Plants of the new Petunia can also be compared to plants of the Petunia x hybrida ‘Keipelcumehus’ , disclosed in U.S. Plant Pat. No. 35,086. In side-by-side comparisons, plants of the new Petunia and ‘Keipekumehus’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia have shorter internodes than plants of ‘Keipekumehus’.
  • 2. Plants of the new Petunia have smaller leaves than plants of ‘Keipekumehus’.
  • 3. Plants of the new Petunia have smaller flowers than plants of ‘Keipekumehus’.
  • 4. Plants of the new Petunia are more freely flowering than plants of ‘Keipekumehus’.
  • 5. Plants of the new Petunia and ‘Keipekumehus’ differ in flower color as flowers of plants of the new Petunia are purplish pink in color with white-colored throats whereas flowers of plants of ‘Keipekumehus’ are reddish purple in color with a white-colored star-shaped pattern and centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Petunia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia plant.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Keipemokohos’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flower of ‘Keipemokohos’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 24-cm containers in a glass-covered greenhouse in Katori, Chiba, Japan and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures averaged 35 C and night temperatures averaged 25 C. Plants were pinched one time and were six months old when the photographs and description were taken.
