USPP19560P2 - Petunia plant named ‘Sunsurfpaspimi’ - Google Patents

Abstract

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

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘SUNSURFPASPIMI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurfpaspimi’.

The new Petunia 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 Petunia cultivars with attractive foliage and flower coloration.

The new Petunia originated from a cross-pollination made by the Inventors in September, 2003 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code number PS203-1, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number PS312-1, not patented, as the male, or pollen, parent. The new Petunia 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.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since September, 2005, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunsurfpaspimi has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Sunsurfpaspimi’. These characteristics in combination distinguish ‘Sunsurfpaspimi’ as a new and distinct cultivar of Petunia:

• • 1. Outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching and flowering plant habit.
  • 4. Long flowering period.
  • 5. Medium-sized pastel pink-colored flowers.
  • 6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Petunia are larger than plants of the female parent selection.
  • 2. Plants of the new Petunia have larger flowers than plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Petunia are more mounding than and not as trailing as plants of the male parent selection.
  • 2. Plants of the new Petunia and the male parent selection differ in flower color as plants of the male parent selection have purple-colored flowers.

Plants of the new Petunia can also be compared to plants of the cultivar Sunsurfcopasaku, disclosed in U.S. Plant Pat. No. 18,122. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and the cultivar Sunsurfcopasaku differed in the following characteristics:

• • 1. Plants of the new Petunia were larger than plants of the cultivar Sunsurfcopasaku.
  • 2. Plants of the new Petunia had larger leaves than plants of the cultivar Sunsurfcopasaku.
  • 3. Plants of the new Petunia had larger flowers than plants of the cultivar Sunsurfcopasaku.
  • 4. Plants of the new Petunia and the cultivar Sunsurfcopasaku differed in petal shape.
