Petunia plant named ‘Kerversalm’

Abstract

A new and distinct cultivar of Petunia plant named ‘Kerversalm’, characterized by its compact and outwardly spreading growth habit; freely branching habit; early and freely flowering habit; dark salmon pink-colored flowers; and good garden performance.

Description

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Kerversalm’.

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 ‘Kerversalm’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Over, Cambridge, United Kingdom. The objective of the breeding program is to create new Petunia cultivars with dark pink-colored flowers.

The new Petunia originated from a cross-pollination made by the Inventors on Aug. 15, 2000 in Over, Cambridge, United Kingdom of a proprietary selection of Petunia×hybrida identified as code number 00-18-3, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number 00-66-1, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Over, Cambridge, United Kingdom on May 31, 2001.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Over, Cambridge, United Kingdom since October, 2001, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Kerversalm 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, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kerversalm’. These characteristics in combination distinguish ‘Kerversalm’ as a new and distinct cultivar of Petunia:

• • 1. Compact and outwardly spreading growth habit.
  • 2. Freely branching habit.
  • 3. Early and freely flowering habit.
  • 4. Dark salmon pink-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 have larger flowers than plants of the female parent selection.
  • 2. Plants of the new Petunia and the female parent selection differ in flower color as plants of the female parent selection have pale pink-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in the flower color as plants of the male parent selection have light pink-colored flowers with white-colored throats.

Plants of the new Petunia can also be compared to plants of the Petunia cultivar Kersamfan, disclosed in U.S. Plant Pat. No. 18,128. In side-by-side comparisons conducted in Over, Cambridge, United Kingdom, plants of the new Petunia differed from plants of the cultivar Kersamfan in the following characteristics:

• • 1. Plants of the new Petunia were more compact and had shorter internodes than plants of the cultivar Kersamfan.
  • 2. Plants of the new Petunia were more freely branching and more freely flowering than plants of the cultivar Kersamfan.
  • 3. Plants of the new Petunia flowered about three days earlier than plants of the cultivar Kersamfan.
  • 4. Plants of the new Petunia had smaller flowers than plants of the cultivar Kersamfan.

DETAILED BOTANICAL DESCRIPTION

The photograph and following observations, measurements and values describe plants grown in Over, Cambridge, United Kingdom, under commercial practice during the summer in a glass-covered greenhouse with day temperatures ranging from 18° C. to 28° C., night temperatures ranging from 14° C. to 20° C. and light levels averaging 50 kilolux. Rooted young plants had been growing for about ten weeks when the photographs and description were taken. Plants were pinched one time before planting.
