Abstract

A new and distinct cultivar of Petunia plant named ‘Sundasiro’, characterized by its semi-upright and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; double-type white-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.
Cultivar denomination: ‘SUNDASIRO’.
CROSS-REFERENCED TO RELATED APPLICATIONS
Title: Petunia Plant Named ‘SUNDAPIN’.
Applicant: Nobutaka AKAI.
Filed: Concurrently with this application (U.S. Plant patent application Ser. No. 13/506,499).
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sundasiro’.
The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Miyazaki-shi, Miyazaki, Japan. The objective of the breeding program is to create new semi-upright and mounding Petunia plants with attractive double-type flowers.
The new Petunia plant is a naturally-occurring branch mutation of a proprietary selection of Petunia×hybrida identified as code name AK-Pet3, not patented. The new Petunia plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of the mutation parent selection in a controlled greenhouse environment in Miyazaki-shi, Miyazaki, Japan in June, 2010.
Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Miyazaki-shi, Miyazaki, Japan since June, 2010 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 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 ‘Sundasiro’. These characteristics in combination distinguish ‘Sundasiro’ as a new and distinct Petunia plant:
    • 1. Semi-upright and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Early and freely flowering habit.
    • 5. Long flowering period.
    • 6. Double-type white-colored flowers.
    • 7. Good garden performance.
Plants of the new Petunia can be compared to plants of the mutation parent selection. Plants of the new Petunia differ primarily from plants of the mutation parent selection in flower color as plants of the mutation parent selection have bright red purple-colored flowers. In addition, plants of the new Petunia have darker green-colored leaves than plants of the mutation parent selection.
Plants of the new Petunia can be compared to plants of the Petunia ‘Sundapin’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Petunia differ primarily from plants of ‘Sundapin’ in flower color as plants of ‘Sundapin’ have light red purple-colored flowers.
Plants of the new Petunia can also be compared to plants of the Petunia ‘AK101’, disclosed in U.S. Plant Pat. No. 21,951. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘AK101’ differed primarily in the following characteristics:
    • 1. Plants of the new Petunia were more upright and mounding than and not as trailing as plants of ‘AK101’.
    • 2. Plants of the new Petunia had shorter lateral branches than plants of ‘AK101’.
    • 3. Plants of the new Petunia had shorter leaves than plants of ‘AK101’.
    • 4. Flowers of plants of the new Petunia were larger and had fewer petals than flowers of plants of ‘AK101’.
    • 5. Plants of the new Petunia and ‘AK101’ differed in flower color as plants of ‘AK101’ had red purple-colored flowers.
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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sundasiro’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sundasiro’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial production.
