Abstract

A new and distinct cultivar of Petunia plant named ‘Sunpetu 761’, characterized by its mounding and trailing plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; flowers that are white in color with a red purple-colored cordate-shaped pattern; and good garden performance.

Description

Botanical designation: Petunia x hybrida.

Cultivar denomination: ‘SUNPETU 761’.

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 ‘Sunpetu 761’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new vigorous, trailing and freely-flowering Petunia plants with attractive flower colors and patterns.

The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2013 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia x hybrida identified as code number MP24-125-2, not patented, as the female, or seed, parent with a proprietary selection of Petunia x hybrida identified as code number MP25-125-2, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in July, 2014.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since January, 2015 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 ‘Sunpetu 761’. These characteristics in combination distinguish ‘Sunpetu 761’ as a new and distinct Petunia plant:

• • 1. Mounding and trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Flowers that are white in color with a red purple-colored cordate-shaped pattern.
  • 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 plants of the new Petunia have white-colored flowers with a red purple-colored cordate pattern whereas plants of the female parent selection have white-colored flowers with a purple-colored picotee pattern.

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 plants of the new Petunia have white-colored flowers with a red purple-colored cordate pattern whereas plants of the male parent selection have white-colored flowers with a light pink-colored cordate pattern.

Plants of the new Petunia can also be compared to plants of the Petunia x hybrida ‘Sunmomoheart’, disclosed in U.S. Plant Pat. No. 28,290. In side-by-side comparisons, plants of the new Petunia and ‘Sunmomoheart’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia are more trailing than and not as mounding as plants of ‘Sunmomoheart’.
  • 2. Plants of the new Petunia are broader than plants of ‘Sunmomoheart’.
  • 3. Leaves of plants of the new Petunia are darker green than leaves of plants of ‘Sunmomoheart’.
  • 4. Plants of the new Petunia are more freely flowering than plants of ‘Sunmomoheart’.
  • 5. Flower petals of plants of the new Petunia are broader than flower petals of plants of ‘Sunmomoheart’.
  • 6. Flowers of plants of the new Petunia have a larger cordate pattern than flowers of plants of ‘Sunmomoheart’.
