Description

Botanical designation: Sanvitalia procumbens.

Cultivar denomination: ‘DOSANSUSUGO24’.

CROSS REFERENCED TO CLOSELY-RELATED APPLICATION:

A European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Dümmen Group B.V. of De Lier, The Netherlands on Oct. 2, 2023, application number 2023/2064 and published on Dec. 15, 2023. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanvitalia plant, botanically known as Sanvitalia procumbens, commonly known as Creeping Zinnia and hereinafter referred to by the name ‘Dosansusugo24’.

The new Sanvitalia 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 and mounding Sanvitalia plants with numerous attractive inflorescences.

The new Sanvitalia plant originated from a cross-pollination conducted by the Inventor in Rheinberg, Germany in July 2020 of a proprietary selection of Sanvitalia procumbens identified as code number LL19-K0006, not patented, as the female, or seed, parent with a proprietary selection of Sanvitalia procumbens identified as code number LL20-K0004, not patented, as the male, or pollen, parent. The new Sanvitalia 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 2021.

Asexual reproduction of the new Sanvitalia plant by vegetative cuttings in a controlled environment in Rheinberg, Germany since April, 2021 has shown that the unique features of this new Sanvitalia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sanvitalia 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 ‘Dosansusugo24’. These characteristics in combination distinguish ‘Dosansusugo24’ as a new and distinct Sanvitalia plant:

• • 1. Relatively compact, semi-upright and mounding plant habit.
  • 2. Relatively moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Inflorescences with bright yellow-colored ray florets and yellowish green-colored disc florets.
  • 6. Good container and garden performance.

Plants of the new Sanvitalia differ primarily from plants of the female and male parent selections in plant habit as plants of the new Sanvitalia are more compact than and not as vigorous as plants of the female and male parent selections.

Plants of the new Sanvitalia can be compared to plants of Sanvitalia procumbens ‘Disangob21’, not patented. In side-by-side comparisons, plants of the new Sanvitalia differ from plants of ‘Disangob21’ in the following characteristics:

• • 1. Plants of the new Sanvitalia are more compact than and not as vigorous as plants of ‘Disangob21’.
  • 2. Plants of the new Sanvitalia are more freely branching than plants of ‘Disangob21’.
  • 3. Plants of the new Sanvitalia have shorter internodes than plants of ‘Disangob21’ giving a denser appearance.
  • 4. Plants of the new Sanvitalia have smaller leaves than plants of ‘Disangob21’.
  • 5. Plants of the new Sanvitalia are more freely flowering than plants of ‘Disangob21’.
  • 6. Inflorescences of plants of the new Sanvitalia have bright yellow-colored ray florets whereas inflorescences of plants of ‘Disangob21’ have orangish yellow-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Sanvitalia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Sanvitalia plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Dosansusugo24’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the spring and summer in 13-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Sanvitalia 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 from planting rooted young plants when the photograph was taken and 25 weeks from planting rooted young plants when the description was taken.
