plant named ‘USTUN47601’

Abstract

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘USTUN47601’.

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 ‘USTUN47601’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new freely-branching and mounding Petunia plants with early and freely flowering habit, attractive medium-sized flowers and good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventor on May 6, 2009 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Petunia×hybrida identified as code number 08P357-02, not patented, as the female, or seed, parent with a proprietary seedling selection of Petunia×hybrida identified as code number 09PJ23, 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 environment in Bonsall, Calif. on May 27, 2010.

Asexual reproduction of the new Petunia plant by vegetative cuttings in a controlled greenhouse environment in Bonsall, Calif. since May 28, 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 practices. 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 ‘USTUN47601’. These characteristics in combination distinguish ‘USTUN47601’ as a new and distinct Petunia plant:

• • 1. Upright to outwardly spreading and low mounding plant habit.
  • 2. Freely branching habit.
  • 3. Vigorous growth habit.
  • 4. Early and freely flowering habit.
  • 5. Medium-sized coral red-colored flowers.
  • 6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Petunia differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Petunia have slightly 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-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Bonsall, Calif., 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 plants of the male parent selection.
  • 2. Plants of the new Petunia have larger flowers than plants of the male parent selection.
  • 3. Plants of the new Petunia and the male parent selection differ in flower color as plants of the male parent selection have lighter-colored flowers.

Plants of the new Petunia can be compared to plants of ‘USTUN19603’, disclosed in U.S. Plant Pat. No. 21,675. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Petunia differed from plants of ‘USTUN19603’ in the following characteristics:

• • 1. Plants of the new Petunia had larger flowers than plants of ‘USTUN19603’.
  • 2. Plants of the new Petunia and ‘USTUN19603’ differed in flower color as plants of ‘USTUN19603’ had bright pink-colored flowers.

Plants of the new Petunia can also be compared to plants of ‘USTUN34803’, disclosed in U.S. Plant Pat. No. 22,884. In side-by-side comparisons, plants of the new Petunia differed from plants of ‘USTUN34803’ in the following characteristics:

• • 1. Plants of the new Petunia had larger flowers than plants of ‘USTUN34803’.
  • 2. Plants of the new Petunia and ‘USTUN34803’ differed in flower color as plants of ‘USTUN34803’ had red purple-colored flowers.
