USPP37023P2 - Petunia plant named ‘INPETTIABL’ - Google Patents

Abstract

A new and distinct Petunia plant named ‘INPETTIABL’, characterized by its upright to outwardly spreading and mounding plant habit to eventually trailing and decumbent plant habit; vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy plant form; early and freely flowering habit; medium-sized single-type flowers that are dark violet in color with light purple-colored centers; and excellent container and garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘INPETTIABL’.

BACKGROUND OF THE INVENTION

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

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the breeding program is to create new vigorous, freely-branching and uniformly mounding Petunia plants with early and freely flowering habit, attractive flowers and good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventor in June 2019 in Heidesheim, Germany of a proprietary selection of Petunia X hybrida identified as code number Pt18-4301-3, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number Pt18-4313-8, 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 greenhouse environment in Heidesheim, Germany in May 2020.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Heidesheim, Germany since June 2020 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 combinations of 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 ‘INPETTIABL’. These characteristics in combination distinguish ‘INPETTIABL’ as a new and distinct Petunia plant:

• • 1. Upright to outwardly spreading and mounding plant habit to eventually trailing and decumbent plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit; dense and bushy plant form.
  • 4. Early and freely flowering habit.
  • 5. Medium-sized single-type flowers that are dark violet in color with light purple-colored centers.
  • 6. Excellent container and garden performance.

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

• • 1. Plants of the new Petunia are more freely branching and denser than and not as open as plants of the female parent selection.
  • 2. Plants of the new Petunia have darker green-colored leaves than plants of the female parent selection.
  • 3. Plants of the new Petunia have larger flowers than plants of the female parent selection.
  • 4. Flowers of plants of the new Petunia are dark violet in color with light purple-colored centers whereas flowers of plants of the female parent selection are purplish lilac in color.
  • 5. Flowers of plants of the new Petunia are bright in color and resist fading whereas flowers of plants of the female parent selection are dull in color and readily fade with subsequent development.

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

• • 1. Plants of the new Petunia are more trailing than and not as upright as plants of the male parent selection.
  • 2. Plants of the new Petunia have darker green-colored leaves than plants of the male parent selection.
  • 3. Plants of the new Petunia have larger flowers than plants of the male parent selection.

Plants of the new Petunia can be compared to plants of Petunia X hybrida Sanguna® ‘Radiant Blue’, not patented. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of Sanguna® ‘Radiant Blue’ in the following characteristics:

• • 1. Plants of the new Petunia have smaller leaves than plants of Sanguna® ‘Radiant Blue’.
  • 2. Leaves of plants of the new Petunia are darker green in color than leaves of plants of Sanguna® ‘Radiant Blue’.
  • 3. Plants of the new Petunia have smaller flowers than plants of Sanguna® ‘Radiant Blue’.
  • 4. Flowers of plants of the new Petunia have smaller lighter-colored centers than flowers of plants of Sanguna® ‘Radiant Blue’.
