Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Petunia×hybrida cultivar Duesurpivein.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Duesurpivein.

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 Petunias with attractive flower colors.

The new Petunia originated from a cross made by the Inventor of a proprietary Petunia selection identified as code number 211-2, not patented, as the female, or seed parent, with a proprietary Petunia selection identified as code number S-16-22, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny by the Inventor in Rheinberg, Germany, on the basis of its attractive flower color.

Asexual reproduction of the new cultivar by terminal vegetative cuttings taken in Rheinberg, 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 Duesurpivein have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 `Duesurpivein`. These characteristics in combination distinguish `Duesurpivein` as a new and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Freely basal branching.

3. Single flowers that are light purple in color with darker purple throat and venation.

Compared to plants of the female parent, the selection 211-2, plants of the new Petunia are more freely flowering, but have smaller flowers. Compared to plants of the male parent, the selection S-16-22, plants of the new Petunia are more freely flowering and have shorter peduncles.

Plants of the new Petunia are similar to plants of the cultivar Surfinia Pink Vein, not patented, in flower color. However, in side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Petunia differed from plants of the cultivar Surfinia Pink Vein in the following characteristics:

1. Plants of the new Petunia had shorter lateral branches than plants of the cultivar Surfinia Pink Vein.

2. Leaves of the new Petunia were lighter green in color than leaves of the cultivar Surfinia Pink Vein.

3. Plants of the new Petunia were more freely flowering than plants of the cultivar Surfinia Pink Vein.

4. Plants of the new Petunia had smaller flowers than plants of the cultivar Surfinia Pink Vein.

5. Plants of the new Petunia had shorter peduncles than plants of the cultivar Surfinia Pink Vein.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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. 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 Petunia.

The photograph comprises a top perspective view of typical flowers, leaves and stems of `Duesurpivein`.

DETAILED BOTANICAL DESCRIPTION

The cultivar Duesurpivein has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Rheinberg, Germany, under commercial practice in a glass-covered greenhouse. Plants were about 16 weeks from cuttings and were grown in containers. During the production of the plants, day and night temperatures averaged 18°C C. and light levels were about 4,500 lux.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, edition 1995, except where general terms of ordinary significance are used.
