Abstract

A new and distinct cultivar of Petunia plant named ‘Kerivoryvein’, characterized by its mounding and semi-trailing growth habit; freely branching habit; early and freely flowering habit; medium-sized white-colored flowers with dark purple-colored centers and venation; and good garden performance.

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘KERIVORYVEIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Kerivoryvein’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Cambridge, United Kingdom. The objective of the breeding program is to create new uniform Petunia plants with attractive flower coloration that are suitable for hanging basket containers.

The new Petunia plant originated from a cross-pollination made by the Inventors in August, 2007 in Cambridge, United Kingdom of a proprietary selection of Petunia×hybrida identified as code number 04-17-1, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number 04-19-4, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Cambridge, United Kingdom in May, 2008.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled greenhouse environment in Cambridge, United Kingdom since September, 2008 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 environmental conditions and cultural practices. The new Petunia plant's phenotype may vary somewhat with variations in environmental conditions and cultural practices 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 ‘Kerivoryvein’. These characteristics in combination distinguish ‘Kerivoryvein’ as a new and distinct Petunia plant:

- 1. Mounding and semi-trailing growth habit.
- 2. Freely branching habit.
- 3. Early and freely flowering habit.
- 4. Medium-sized white-colored flowers with dark purple-colored centers and venation.
- 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 mounding than and not as trailing as plants of the female parent selection.
- 2. Plants of the new Petunia have larger flowers than plants of the female parent selection.
- 3. Flowers of plants of the new Petunia and the female parent selection differ slightly in venation color.

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 are more mounding than and not as upright as plants of the male parent selection.
- 2. Plants of the new Petunia have smaller flowers than plants of the male parent selection.
- 3. Flowers of plants of the new Petunia and the male parent selection differ in flower color as plants of the male parent selection have light yellow-colored flowers with reddish brown-colored venation.

Plants of the new Petunia can be compared to plants of the Petunia ‘Kakegawa S30’, disclosed in U.S. Plant Pat. No. 13,862. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Petunia differed from plants of ‘Kakegawa S30’ in the following characteristics:

- 1. Plants of the new Petunia were more upright than and not as trailing as plants of ‘Kakegawa S30’.
- 2. Plants of the new Petunia had larger leaves than plants of ‘Kakegawa S30’.
- 3. Plants of the new Petunia and ‘Kakegawa S30’ differed in flower color as plants of ‘Kakegawa S30’ had solid white-colored flowers.

Plants of the new Petunia can also be compared to plants of the Petunia ‘Lanbor’, disclosed in U.S. Plant Pat. No. 16,144. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Petunia differed from plants of ‘Lanbor’ in the following characteristics:

- 1. Plants of the new Petunia were less vigorous than plants of ‘Lanbor’.
- 2. Plants of the new Petunia and ‘Lanbor’ differed in flower color as plants of ‘Lanbor’ had light purple-colored flowers with dark purple-colored centers and venation.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet comprises a side perspective view of typical plants of ‘Kerivoryvein’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flower of ‘Kerivoryvein’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 20-cm containers during the summer in a glass-covered greenhouse in Cambridge, United Kingdom and under commercial cultural practices. During the production of the plants, day temperatures ranged from 18° C. to 28° C., night temperatures ranged from 14° C. to 20° C. and light levels averaged 50 kilolux. Plants were pinched one time and were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
