USPP21900P2 - Chrysanthemum plant named ‘Olmeto Orange’ - Google Patents

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Olmeto Orange’, characterized by its compact, upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full plant habit; uniform, early and freely flowering habit; and large decorative-type inflorescences with dark and light orange-colored ray florets.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘OLMETO ORANGE’.

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 ‘Olmeto Orange’.

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 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 October, 2004 of Chrysanthemum×morifolium ‘Forza Red’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Masculino Orange’, 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, 2005.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2006. 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 ‘Olmeto Orange’. These characteristics in combination distinguish ‘Olmeto Orange’ as a new and distinct Chrysanthemum cultivar:

• • 1. Compact, upright, outwardly spreading and rounded plant habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Uniform, early and freely flowering habit.
  • 4. Large decorative-type inflorescences with dark and light orange-colored ray florets.

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

• • 1. Plants of the new Chrysanthemum are more rounded than plants of ‘Forza Red’.
  • 2. Plants of the new Chrysanthemum are not as vigorous as plants of ‘Forza Red’.
  • 3. Plants of the new Chrysanthemum have smaller leaves than plants of ‘Forza Red’.
  • 4. Plants of the new Chrysanthemum flower earlier than plants of ‘Forza Red’.

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

• • 1. Stems of plants of the new Chrysanthemum are more flexible than and not as brittle as stems of plants of ‘Masculino Orange’.
  • 2. Plants of the new Chrysanthemum have more leaves than plants of ‘Masculino Orange’.
  • 3. Plants of the new Chrysanthemum flower later than plants of ‘Masculino Orange’.
  • 4. Plants of the new Chrysanthemum and ‘Masculino Orange’ differ in inflorescence type.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Elda Orange’, not patented. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Elda Orange’ in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered more uniformly than plants of ‘Elda Orange’.
  • 2. Plants of the new Chrysanthemum and ‘Elda Orange’ differed in ray floret color as plants of ‘Elda Orange’ had orange-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant. 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 Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Olmeto Orange’ 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 and 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.
