Description

Botanical designation: Petunia x hybrida.

Cultivar denomination: ‘SURF GONITOMI’.

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 ‘Surf Gonitomi’.

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 semi-spreading, mounding and freely-flowering Petunia plants with medium-sized attractive flowers.

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 designation PV555-5, not patented, as the female, or seed, parent with a proprietary selection of Petunia x hybrida identified as code designation 13CV-7, 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 ‘Surf Gonitomi’. These characteristics in combination distinguish ‘Surf Gonitomi’ as a new and distinct Petunia plant:

• • 1. Semi-spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Medium-sized flowers that are bright red purple and white in color.
  • 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 female parent selection have light salmon pink-colored flowers.

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 growth habit as plants of the new Petunia are more vigorous than and not as compact as plants of the male parent selection.

Plants of the new Petunia can also be compared to plants of the Petunia x hybrida ‘USTUN69002’, disclosed in U.S. Plant Pat. No. 27,727. In side-by-side comparisons, plants of the new Petunia and ‘USTUN69002’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia are not as compact as plants of ‘USTUN69002’.
  • 2. Plants of the new Petunia flower earlier than plants of ‘USTUN69002’.
  • 3. Plants of the new Petunia have larger flowers than plants of ‘USTUN69002’.
  • 4. Plants of the new Petunia and ‘USTUN69002’ differ in flower color as plants of ‘USTUN69002’ have lavender pink-colored flowers.
