Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Antica Bronze’, characterized by its upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; and decorative-type inflorescences that are initially red in color becoming reddish orange bronze to lighter orange bronze with development.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘ANTICA BRONZE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Antica Bronze’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.

The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in September, 2008 of Chrysanthemum×morifolium ‘Luciano’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Carpino Red’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2009.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in February, 2010. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Antica Bronze’. These characteristics in combination distinguish ‘Antica Bronze’ as a new and distinct Chrysanthemum cultivar:

- 1. Upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Uniform and freely flowering habit.
- 4. Decorative-type inflorescences that are initially red in color becoming reddish orange bronze to lighter orange bronze with development.

Plants of the new Chrysanthemum differ from the female parent, ‘Luciano’, in the following characteristics:

- 1. Plants of the new Chrysanthemum are more rounded than plants of ‘Luciano’.
- 2. Plants of the new Chrysanthemum are more flexible than and not as brittle as plants of ‘Luciano’.
- 3. Plants of the new Chrysanthemum have larger inflorescences than plants of ‘Luciano’.
- 4. Plants of the new Chrysanthemum and ‘Luciano’ differ in ray floret color as plants of ‘Luciano’ have bright orange-colored ray florets.

Plants of the new Chrysanthemum differ from the male parent, ‘Carpino Red’, in the following characteristics:

- 1. Plants of the new Chrysanthemum are more rounded than plants of ‘Carpino Red’.
- 2. Leaves of plants of the new Chrysanthemum are smaller and slightly lighter green in color than leaves of plants of ‘Luciano’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘PPP PIZ R05’, disclosed in U.S. Plant Pat. No. 18,059. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘PPP PIZ R05’ in the following characteristics:

- 1. Leaves of plants of the new Chrysanthemum were darker green in color than leaves of plants of ‘PPP PIZ R05’.
- 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of ‘PPP PIZ R05’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant 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 Chrysanthemum plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Antica Bronze’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer to late autumn under conditions and practices which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
