plant named ‘Sunsurfcopavio’

Abstract

A new and distinct cultivar of Petunia plant named ‘Sunsurfcopavio’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching and flowering plant habit; long flowering period; dark purple violet-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Sunsurfcopavio’.

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 ‘Sunsurfcopavio’.

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 compact and mounding Petunia cultivars with freely branching habit and attractive flower coloration.

The new Petunia plant originated from a cross-pollination made by the Inventors in April, 2003 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code number PF4, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number LV-01, 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 in September, 2005.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2005, 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. 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 ‘Sunsurfcopavio’. These characteristics in combination distinguish ‘Sunsurfcopavio’ as a new and distinct cultivar of Petunia:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching and flowering plant habit.
  • 4. Long flowering period.
  • 5. Dark purple violet-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 more compact and mounding than and not as trailing as plants of the female parent selection.
  • 2. Plants of the new Petunia have smaller 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 compact and mounding than and not as upright as plants of the male parent selection.
  • 2. 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 ‘Keipabukas’, disclosed in U.S. Plant Pat. No. 14,748. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Keipabukas’ differed in the following characteristics:

• • 1. Plants of the new Petunia were more compact and mounding than plants of ‘Keipabukas’.
  • 2. Plants of the new Petunia had shorter internodes than plants of ‘Keipabukas’.
  • 3. Plants of the new Petunia had smaller leaves than plants of ‘Keipabukas’.
  • 4. Plants of the new Petunia had larger flowers than plants of ‘Keipabukas’.
  • 5. Flowers of plants of the new Petunia and ‘Keipabukas’ differed in color as flowers of plants of ‘Keipabukas’ had more violet-colored flowers.
