Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Sinelli Yellow’, characterized by its uniform, upright, outwardly spreading and rounded plant habit; vigorous growth habit; freely branching habit; dense and full plant habit; uniform, early and freely flowering habit; large decorative-type inflorescences with yellow orange-colored ray florets; and excellent garden performance.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘SINELLI YELLOW’.

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 ‘Sinelli Yellow’.

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 September, 2004 of Chrysanthemum×morifolium ‘Axima Yellow’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Gold Finch’, 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 September, 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 and cultural 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 ‘Sinelli Yellow’. These characteristics in combination distinguish ‘Sinelli Yellow’ as a new and distinct Chrysanthemum plant:

- 1. Uniform, upright, outwardly spreading and rounded plant habit; vigorous growth habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Uniform, early and freely flowering habit.
- 4. Large decorative-type inflorescences with yellow orange-colored ray florets.
- 5. Excellent garden performance.

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

- 1. Plants of the new Chrysanthemum are more vigorous than plants of ‘Axima Yellow’.
- 2. Plants of the new Chrysanthemum are more rounded than and not as upright as plants of ‘Axima Yellow’.
- 3. Ray florets of plants of the new Chrysanthemum are darker in color than ray florets plants of ‘Axima Yellow’.

Plants of the new Chrysanthemum differ primarily from the male parent, ‘Gold Finch’, in the following characteristics:

- 1. Plants of the new Chrysanthemum are more vigorous and larger than plants of ‘Gold Finch’.
- 2. Inflorescences of plants of the new Chrysanthemum are decorative in form whereas inflorescences of plants of ‘Gold Finch’ are pompon in form.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Allegra Yellow’, disclosed in U.S. Plant Pat. No. 21,785. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Allegra Yellow’ in the following characteristics:

- 1. Plants of the new Chrysanthemum were not as compact as plants of ‘Allegra Yellow’.
- 2. Plants of the new Chrysanthemum and ‘Allegra Yellow’ differed in leaf shape.
- 3 Plants of the new Chrysanthemum flowered later than plants of ‘Allegra Yellow’.

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 ‘Sinelli Yellow’ 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 and under conditions and practices which approximate those generally used in commercial Chrysanthemum 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.
