Carnation plant named ‘Kobianca’

Abstract

A new and distinct cultivar of Carnation plant named ‘Kobianca’, characterized by its compact, upright, somewhat outwardly spreading and mounded plant habit; moderately vigorous growth habit; freely branching habit; numerous double red purple and white bi-colored that are positioned above and beyond the foliage; and good flower longevity.

Description

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘Kobianca’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus, grown as a potted plant, and hereinafter referred to by the name ‘Kobianca’.

The new Carnation is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new freely-branching Carnation cultivars with numerous flowers and attractive flower coloration.

The new Carnation originated from a cross-pollination made by the Inventor in July, 2002, of a proprietary selection of Dianthus caryophyllus identified as code number 200376, not patented, as the female, or seed, parent with a proprietary selection of Dianthus caryophyllus identified as code number 996355, not patented, as the male, or pollen, parent. The cultivar Kobianca was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands.

Asexual reproduction of the new cultivar by terminal cuttings propagated in a controlled environment in Aalsmeer, The Netherlands since 2002, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar Kobianca has 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 ‘Kobianca’. These characteristics in combination distinguish ‘Kobianca’ as a new and distinct cultivar of Carnation:

• • 1. Compact, upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Numerous double red purple and white bi-colored that are positioned above and beyond the foliage.
  • 5. Good flower longevity.

Plants of the new Carnation differ from plants of the parent selections primarily in flower color. In addition, plants of the new Carnation differ from plants of the parent selections in growth habit as plants of the new Carnation are more compact than plants of the parent selections.

Plants of the new Carnation can be compared to plants of the Carnation cultivar Margarita, disclosed in U.S. Plant Pat. No. 17,335. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Carnation differed from plants of the cultivar Margarita in the following characteristics:

• • 1. Plants of the new Carnation were more compact than plants of the cultivar Margarita.
  • 2. Plants of the new Carnation were more freely branching than plants of the cultivar Margarita.
  • 3. Plants of the new Carnation had shorter leaves than plants of the cultivar Margarita.
  • 4. Flowers of plants of the new Carnation had more petals than flowers of plants of the cultivar Margarita.
  • 5. Petals of plants of the new Carnation had entire margins whereas petals of plants of the cultivar Margarita had serrated margins.
  • 6. Flowers of plants of the new Carnation were more intense in color than flowers of plants of the cultivar Margarita.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation. This photograph shows 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 Carnation. The photograph comprises a side perspective view of a typical flowering plant of ‘Kobianca’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

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. Measurements and numerical values represent averages for typical flowering plants. The aforementioned photograph and following observations and measurements describe plants grown in Aalsmeer, The Netherlands during the spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial potted Carnation production. During the production of the plants, day temperatures ranged from 15° C. to 25° C. and night temperatures ranged from 10° C. to 12° C. Single plants were grown in 10-cm pots and were pinched one time. Plants were about four months old when the photograph and the detailed description were taken.
