Abstract: A new and distinct cultivar of Petunia plant named `Dueswesurlav`, characterized by its outwardly spreading to trailing growth habit; freely branching habit; early and freely flowering habit; purple-colored flowers; and good garden performance.
Claim: It is claimed:

1. A new and distinct Petunia plant named `Dueswesurlav` as illustrated and described.
Description: Botanical designation:Petunia.times.hybrida.

Cultivar denomination: `DUESWESURLAV`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia.times.hybrida and hereinafter referred to by the name `Dueswesurlav`.

The new Petunia 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 Petunia cultivars with early and freely flowering habit, and unique and attractiveflower color.

The new Petunia originated from a cross-pollination made by the Inventor in August, 2004 in Rheinberg, Germany of a proprietary selection of Petunia.times.hybrida identified as code number S-19-12, not patented, as the female, or seed, parentwith a proprietary selection of Petunia.times.hybrida identified as code number 01-0018-7, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventor as a single flowering plant within the progeny of thestated cross-pollination in a controlled environment in Rheinberg, Germany in May, 2005.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Rheinberg, Germany since July, 2005, has shown that the unique features of this new Petunia are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The cultivar Dueswesurlav has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Dueswesurlav`. These characteristics in combination distinguish `Dueswesurlav` as a new and distinct cultivar of Petunia: 1. Outwardlyspreading to trailing growth habit. 2. Freely branching habit. 3. Early and freely flowering habit. 4. Purple-colored flowers. 5. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ from plants of the female parent selection in the following characteristics: 1. Plants of the new Petunia are more compact thanplants of the female parent selection. 2. Plants of the new Petunia have smaller leaves than plants of the female parent selection. 3. Plants of the new Petunia have smaller flowers than plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Petunia have smaller flowers thanplants of the male parent selection. 2. Plants of the new Petunia and the male parent selection differ in flower color as plants of the male parent selection have pink-colored flowers.

Plants of the new Petunia can also be compared to plants of the Petunia cultivar Duesurlav, disclosed in U.S. Plant Pat. No. 13,553. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Petunia differed from plants ofthe cultivar Duesurlav in the following characteristics: 1. Plants of the new Petunia were more compact than plants of the cultivar Duesurlav. 2. Plants of the new Petunia had shorter internodes than plants of the cultivar Duesurlav. 3. Plants ofthe new Petunia had smaller leaves and shorter petioles than plants of the cultivar Duesurlav. 4. Plants of the new Petunia had smaller flowers than plants of the cultivar Duesurlav. 5. Plants of the new Petunia had shorter peduncles than plants ofthe cultivar Duesurlav.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Petunia, 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 fromthe color values cited in the detailed botanical description which accurately describe the colors of the new Petunia. The photograph comprises a close-up view of typical leaves and flowers of `Dueswesurlav`.

DETAILED BOTANICAL DESCRIPTION

The photograph and following observations, measurements and values describe plants grown in Rheinberg, Germany, under commercial practice during the spring in a glass-covered greenhouse with day and night temperatures averaging 18.degree. C. andlight levels averaging 4,500 lux. Rooted young plants had been growing for about 16 weeks when the photograph and description were taken. Plants were pinched one time about three weeks after planting.
