Abstract

A distinct cultivar of Petunia plant named `Weswei`, characterized by its dark green leaves; numerous pure white flowers; cascading and freely branching growth habit; early flowering; and good weather tolerance, particularly tolerant to rain, wind and low temperatures.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia axillaris, and hereinafter referred to by the cultivar name Weswei.
The new Petunia is a product of a planned breeding program conducted by the Inventor in Sudlohn-Oeding, Germany. The new Petunia originated from a cross made by the Inventor in 1996 of the nonpatented Petunia axillaris cultivar Sylvana White as the female, or seed, parent with a seedling selection of Petunia axillaris identified as Sylvana 95/076 as the male, or pollen, parent.
Asexual reproduction of the new cultivar by terminal cuttings taken at Sudlohn-Oeding, Germany, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Weswei have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Weswei`. These characteristics in combination distinguish `Weswei` as a new and distinct cultivar:
1. Dark green leaves.
2. Numerous pure white flowers.
3. Cascading and freely branching growth habit.
4. Relatively early flowering.
5. Good weather tolerance, particularly tolerant to rain, wind and low temperatures.
Plants of the cultivar Weswei can be compared to plants of the female parent, the cultivar Sylvana White. However in side-by-side comparisons conducted in Sudlohn-Oeding, Germany, plants of the cultivar Weswei differ from plants of the cultivar Sylvana White in the following characteristics:
1. Leaves of plants of the new Petunia are larger, more rounded, darker green and have longer petioles than leaves of plants of the cultivar Sylvana White.
2. Plants of the new Petunia have larger flowers than plants of the cultivar Sylvana White.
3. Plants of the new Petunia have pure white-colored flowers whereas plants of the cultivar Sylvana White have very light pink-colored flowers.
4. Plants of the new Petunia have longer and darker green peduncles than plants of the cultivar Sylvana White.
5. Plants of the new Petunia have darker green sepals than plants of the cultivar Sylvana White.
Plants of the cultivar Weswei are similar in flower color to plants of the nonpatented Surfinia White. However in side-by-side comparisons conducted in Sudlohn-Oeding, Germany, plants of the cultivar Weswei differ from plants of the cultivar Surfinia White in the following characteristics:
1. Plants of the new Petunia are more compact than plants of the cultivar Surfinia White.
2. Leaves of plants of the new Petunia are smaller and darker green than leaves of plants of the cultivar Surfinia White.
3. Plants of the new Petunia are more floriferous than plants of the cultivar Surfinia White.
4. Plants of the new Petunia flower earlier than plants of the cultivar Surfinia White.
5. Flower petals of plants of the new Petunia do not have as prominent veins as flower petals of plants of the cultivar Surfinia White.
6. Flowers of plants of the new Petunia have longer peduncles than flowers of plants of the cultivar Surfinia White.
7. Flowers of plants of the new Petunia have light lilac-colored stamens and pollen whereas flowers of plants of the cultivar Surfinia White have ivory-colored stamens and pollen.
8. Plants of the new Petunia exhibit better weather tolerance, particularly to rain, than plants of the cultivar Surfinia White.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph on the first sheet comprises a side perspective view of a large basket of plants of the new Petunia.
The photograph on the second sheet comprises a close-up view of a typical flower of the new Petunia. Flower and foliage colors in the photographs may appear different than the actual colors due to light reflectance.
