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 ‘Dopetsurspare 23’.
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 2020 in Rheinberg, Germany of a proprietary selection of Petunia X hybrida identified as code number TT-1089, not patented, as the female, or seed, parent with a proprietary selection of Petunia X hybrida identified as code number TT20-K0810, 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 May 2021.
Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since May 2021 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 ‘Dopetsurspare 23’. These characteristics in combination distinguish ‘Dopetsurspare 23’ as a new and distinct Petunia plant:
- 1. Relatively 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 deep red-colored flowers with numerous white- colored spots.
- 6. Good 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 not as vigorous as plants of the female parent selection.
- 2. Plants of the new Petunia are more freely branching than plants of the female parent selection.
- 3. Flowers of plants of the new Petunia are deep red in color with numerous white-colored spots whereas flowers of plants of the female parent selection are solid red in color without any spots.
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 freely branching than plants of the male parent selection.
- 2. Plants of the new Petunia are more freely flowering than plants of the male parent selection.
- 3. Flowers of plants of the new Petunia are deep red in color with numerous white-colored spots whereas flowers of plants of the male parent selection are purple with white-colored spots.
- 4. Flower spotted pattern of plants of the new Petunia is more stable than flower spotted pattern of plants of the male parent selection.
Plants of the new Petunia can be compared to plants of Petunia X hybrida ‘KLEPH15313’, disclosed in U.S. Plant Pat. No. 27,237. In side-by-side comparisons, plants of the new Petunia and ‘KLEPH15313’ differ primarily in the following characteristics:
- 1. Plants of the new Petunia are not as vigorous as plants of ‘KLEPH15313’.
- 2. Leaves of plants of the new Petunia are darker green in color than leaves of plants of ‘KLEPH15313’.
- 3. Plants of the new Petunia have larger flowers than plants of ‘KLEPH15313’.
- 4. Flowers of plants of the new Petunia are deep red in color with numerous white-colored spots whereas flowers of plants of ‘KLEPH15313’ are blue in color with numerous white-colored spots.

DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and early summer in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Petunia production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were twelve weeks old when the photographs were taken and 25 weeks old when the description was taken.
