plant named ‘INPETROYMA’

Abstract

A new and distinct Petunia plant named ‘INPETROYMA’, characterized by its compact, outwardly spreading and mounding to eventually trailing plant habit; freely branching habit; moderately vigorous growth habit; early and freely flowering habit; large dark red purple-colored flowers with dark purple-colored venation and throats; and good garden performance.

Description

Botanical designation: Petunia X hybrida.

Cultivar denomination: ‘INPETROYMA’.

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 ‘INPETROYMA’.

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

The new Petunia plant originated from a cross-pollination made by the Inventor in December, 2013 in Johannesburg, South Africa of Petunia X hybrida ‘Sunremi’, disclosed in U.S. Plant Pat. No. 16,803, as the female, or seed, parent and Petunia X hybrida ‘USTUNI8902’, disclosed in U.S. Plant Pat. No. 17,895, 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 July, 2014.

Asexual reproduction of the new Petunia plant by vegetative terminal cuttings in a controlled greenhouse environment in Heidesheim, Germany since August, 2014 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 ‘INPETROYMA’. These characteristics in combination distinguish ‘INPETROYMA’ as a new and distinct Petunia plant:

• • 1. Compact, outwardly spreading and mounding to eventually trailing plant habit.
  • 2. Freely branching habit.
  • 3. Moderately vigorous growth habit.
  • 4. Early and freely flowering habit.
  • 5. Large dark red purple-colored flowers with dark purple-colored venation and throats.
  • 6. Good garden performance.

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

• • 1. Plants of the new Petunia are more trailing than and not as upright as ‘Sunremi’.
  • 2. Plants of the new Petunia and ‘Sunremi’ differ in flower color as plants of ‘Sunremi’ have red-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent, ‘USTUNI8902’. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘USTUNI8902’ in the following characteristics:

• • 1. Plants of the new Petunia are more compact than plants of ‘USTUNI8902’.
  • 2. Plants of the new Petunia flower earlier than plants of ‘USTUNI8902’.
  • 3. Plants of the new Petunia and ‘USTUNI8902’ differ in flower color as plants of ‘USTUNI8902’ have brighter and more reddish-colored flowers.

Plants of the new Petunia can be compared to plants of ‘Kakegawa S36’, disclosed in U.S. Plant Pat. No. 14,037. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Kakegawa S36’ in the following characteristics:

• • 1. Plants of the new Petunia are more freely branching than plants of ‘Kakegawa S36’.
  • 2. Leaves of plants of the new Petunia are smaller than leaves of plants of ‘Kakegawa S36’.
  • 3. Plants of the new Petunia are more freely flowering than plants of ‘Kakegawa S36’.
  • 4. Flowers of plants of the new Petunia are slightly smaller than flowers of plants of ‘Kakegawa S36’.

Plants of the new Petunia can also be compared to plants of ‘Kakegawa S28’, disclosed in U.S. Plant Pat. No. 13,887. In side-by-side comparisons, plants of the new Petunia differ primarily from plants of ‘Kakegawa S28’ in the following characteristics:

• • 1. Plants of the new Petunia are more freely branching than plants of ‘Kakegawa S28’.
  • 2. Plants of the new Petunia are more freely flowering than plants of ‘Kakegawa S28’.
  • 3. Plants of the new Petunia and ‘Kakegawa S28’ differ in flower color as plants of ‘Kakegawa S28’ have dark purple-colored flowers.
