plant named ‘Sunsurfpitora’

Abstract

A new and distinct cultivar of Petunia plant named ‘Sunsurfpitora’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; medium-sized salmon pink-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘SUNSURFPITORA’.

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 ‘Sunsurfpitora’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new freely branching Petunia plants with mounding habit and attractive flower coloration.

The new Petunia plant originated from a cross-pollination made by the Inventors in April, 2004 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code name Px256-03, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code name FTSMP, 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 environment in Higashiomi, Shiga, Japan in September, 2008.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2008, 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 ‘Sunsurfpitora’. These characteristics in combination distinguish ‘Sunsurfpitora’ as a new and distinct Petunia plant:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Long flowering period.
  • 6. Medium-sized salmon pink-colored flowers.
  • 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 the following characteristics:

• • 1. Plants of the new Petunia have smaller flowers than plants of the female parent selection.
  • 2. Plants of the new Petunia and the female parent selection differ in flower color as plants of the female parent selection have darker 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 flower size as plants of the new Petunia have larger flowers than plants of the male parent selection.

Plants of the new Petunia can also be compared to plants of the Petunia ‘Sunsurfcoparu’, disclosed in U.S. Plant Pat. No. 18,141. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Sunsurfcoparu’ differed primarily in the following characteristics:

• • 1. Plants of the new Petunia had shorter internodes than plants of ‘Sunsurfcoparu’.
  • 2. Plants of the new Petunia had smaller leaves with shorter petioles than plants of ‘Sunsurfcoparu’.
  • 3. Plants of the new Petunia and ‘Sunsurfcoparu’ differed in flower color as plants of ‘Sunsurfcoparu’ had red purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and early summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under commercial practices typical for Petunia production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and description were taken.
