Abstract

A new and distinct cultivar of Chrysanthemum plant named `Fimmevenyel`, characterized by its upright to outwardly spreading and uniformly mounded plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; small-size decorative-type inflorescences with bright yellow-colored ray florets; mid season-flowering habit; and good garden performance.

Description

Botanical designation: Chrysanthemum.times.morifolium.

Cultivar denomination: `FIMMEVENYEL`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium, commercially grown as a garden Chrysanthemum plant and hereinafter referred to by the name `Fimmevenyel`.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Fareham, Hampshire, United Kingdom. The objective of the breeding program is to create new mid season-flowering garden Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination made in January, 2010 by the Inventor in Fareham, Hampshire, United Kingdom of a proprietary selection of Chrysanthemum.times.morifolium identified as code number 82983, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum.times.morifolium identified as code number 82563, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fareham, Hampshire, United Kingdom in September, 2010.

Asexual reproduction of the new Chrysanthemum plant by terminal vegetative cuttings was first conducted in Fareham, Hampshire, United Kingdom in December, 2010. Asexual reproduction by terminal vegetative 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 `Fimmevenyel`. These characteristics in combination distinguish `Fimmevenyel` as a new and distinct Chrysanthemum plant: 1. Upright to outwardly spreading and uniformly mounded plant habit. 2. Freely branching habit; dense and full plant habit. 3. Uniform and freely flowering habit. 4. Small-size decorative-type inflorescences with bright yellow-colored ray florets. 5. Mid season-flowering habit; grown under natural season conditions, plants flower in mid to late September in the United Kingdom. 6. Good garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics: 1. Plants of the new Chrysanthemum have smaller inflorescences than plants of the female parent selection. 2. Plants of the new Chrysanthemum and the female parent selection differ in ray floret color as plants of the female parent selection have purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ from plants of the male parent selection, in the following characteristics: 1. Grown under natural season conditions, plants of the new Chrysanthemum flower earlier than plants of the male parent selection. 2. Plants of the new Chrysanthemum and the male parent selection differ in inflorescence form as plants of the male parent selection have semi-decorative-type inflorescences.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum.times.morifolium `Sunny Yoursula`, disclosed in U.S. Plant Pat. No. 16,281. In side-by-side comparisons conducted in Fareham, Hampshire, United Kingdom, plants of the new Chrysanthemum differed from plants of `Sunny Yoursula` in the following characteristics: 1. Plants of the new Chrysanthemum had slightly smaller inflorescences than plants of `Sunny Yoursula`. 2. Grown under natural season conditions, plants of the new Chrysanthemum flowered later than plants of `Sunny Yoursula`.

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 top perspective view of a typical flowering plant of `Fimmevenyel` grown in a 19-cm container during the summer and autumn in a glass-covered greenhouse in De Lier, The Netherlands. Plants were grown under natural season conditions. Plants were 3.5 months old when the photograph was taken.

DETAILED BOTANICAL DESCRIPTION

The following observations and measurements describe plants grown during the winter in 14-cm containers in a glass-covered greenhouse in Fareham, Hampshire, United Kingdom and under cultural practices typical of commercial garden Chrysanthemum production. During the production of the plants, day and night temperatures ranged from 17.degree. C. to 21.degree. C. and light levels averaged 6,000 lux. Plants were grown under long day/short night conditions for six weeks and then grown under short day/long night conditions to induce inflorescence initiation and development. Plants were twelve weeks old when the detailed description was taken.
