Abstract
Description
[0001] Botanical designation: Petunia x hybrida.
[0002] Cultivar denomination: ‘Surf 20511’.BACKGROUND OF THE INVENTION
[0003] 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 20511’.
[0004] 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 outwardly spreading and freely-branching habit Petunia plants with numerous small white-colored flowers.
[0005] The new Petunia plant originated from a cross-pollination made by the Inventor in June, 2020 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia x hybrida identified as code designation PV1835-1,not patented, as the female, or seed, parent with a proprietary selection of Petunia x hybrida identified as code designation PV1984-3, 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 June, 2021.
[0006] Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April 2022 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
[0007] 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.
[0008] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Surf 20511’. These characteristics in combination distinguish ‘Surf 20511’ as a new and distinct Petunia plant:
[0009] 1. Upright to outwardly spreading plant habit.
[0010] 2. Vigorous growth habit.
[0011] 3. Freely branching habit.
[0012] 4. Freely flowering habit.
[0013] 5. Long flowering period.
[0014] 6. Flowers that are white in color with light purple-colored throats and venation.
[0015] 7. Good garden performance.
[0016] 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 white in color with light purple-colored throats and venation whereas flowers of plants of the female parent selection are purple in color. In addition, plants of the new Petunia have smaller flowers than plants of the female parent selection.
[0017] 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 white in color with light purple-colored throats and venation whereas flowers of plants of the male parent selection are solid white in color. In addition, plants of the new Petunia have smaller flowers than plants of the male parent selection.
[0018] Plants of the new Petunia can also be compared to plants of the Petunia x hybrida ‘Sunsurfsirou’, disclosed in U.S. Plant Pat. No. 24,453. In side-by-side comparisons, plants of the new Petunia and ‘Sunsurfsirou’ differ primarily in the following characteristics:
[0019] 1. Plants of the new Petunia are more upright than and not as spreading and mounding as plants of ‘Sunsurfsirou’.
[0020] 2. Plants of the new Petunia are more freely flowering than plants of ‘Sunsurfsirou’.
[0021] 3. Plants of the new Petunia have smaller flowers than plants of ‘Sunsurfsirou’.
[0022] 4. Plants of the new Petunia and ‘Sunsurfsirou’ differ in flower venation color as flowers of plants of the new Petunia have light purple-colored venation whereas flowers of plants of ‘Sunsurfsirou’ have light yellowish green-colored venation.BRIEF DESCRIPTION OF THE PHOTOGRAPHS
[0023] 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.
[0024] The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Surf 20511’ grown in a container.
[0025] The photograph on the second sheet (FIG. 2) is a close-up view of a typical flower of ‘Surf 20511’.DETAILED BOTANICAL DESCRIPTION
