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 ‘Dopetsurye 25’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact, freely branching and early-flowering Petunia plants with numerous attractive flowers.

The new Petunia plant originated from a cross-pollination made by the Inventor in July, 2022 in Rheinberg, Germany of a proprietary selection of Petunia X hybrida identified as code number TT22-K0658, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number TT22-K0259, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in April, 2023.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since April, 2023 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 ‘Dopetsurye 25’. These characteristics in combination distinguish ‘Dopetsurye 25’ as a new and distinct Petunia plant:

• • 1. Compact, upright and mounding to hanging plant habit.
  • 2. Moderately vigorous growth habit and moderate growth rate.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Large greenish yellow-colored flowers.
  • 6. Good garden performance.
  • 7. Resistant to Tobacco Mosaic Virus (TMV).

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 than plants of the female parent selection.
  • 2. Plants of the new Petunia are more freely flowering than plants of the female parent selection.
  • 3. Plants of the new Petunia are more tolerant to high temperatures than plants of the female parent selection.

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 compact than plants of the male parent selection.
  • 2. Flowers of plants of the new Petunia are more rounded in shape than flowers of plants of the male parent selection.
  • 3. Plants of the new Petunia are resistant to Tobacco Mosaic Virus whereas plants of the male parent selection are not resistant to Tobacco Mosaic Virus.

Plants of the new Petunia can be compared to plants of Petunia X hybrida ‘Go!Tunia Hello Yellow’, not patented. In side-by-side comparisons, plants of the new Petunia and ‘Go!Tunia Hello Yellow’ differ primarily in the following characteristics:

• • 1. Plants of the new Petunia are more compact than plants of ‘Go!Tunia Hello Yellow’.
  • 2. Plants of the new Petunia are denser than and not as open as plants of ‘Go!Tunia Hello Yellow’.
  • 3. Plants of the new Petunia have smaller leaves than plants of ‘Go!Tunia Hello Yellow’.
  • 4. Plants of the new Petunia are resistant to Tobacco Mosaic Virus whereas plants of ‘Go!Tunia Hello Yellow’ are not resistant to Tobacco Mosaic Virus.
