Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘Yomia’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yomia’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.
The new Chrysanthemum originated from a cross-pollination made in 2001 in Salinas, Calif., of two unnamed proprietary selections of Chrysanthemum×morifolium, not patented. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Alva, Fla. in November, 2002. The selection of this plant was based on its desirable inflorescence form, attractive floret coloration and good garden performance.
Asexual reproduction of the new cultivar by terminal vegetative cutting in a controlled environment in Alva, Fla. since January, 2003, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe cultivar Yomia has 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 ‘Yomia’. These characteristics in combination distinguish ‘Yomia’ as a new and distinct cultivar:
-
- 1. Compact, upright and outwardly spreading plant habit.
- 2. Freely branching habit; dense and full plants.
- 3. Uniform and freely flowering habit.
- 4. Small decorative button-type inflorescences with elongated oblong-shaped ray florets.
- 5. Lavender-colored ray florets.
- 6. Natural season flowering in mid-September in the Northern Hemisphere.
Plants of the new Chrysanthemum differ from plants of the parent selections primarily in plant habit, ray floret coloration and flowering response time.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Barbara, disclosed in U.S. Plant Pat. No. 8,607. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Barbara in the following characteristics:
-
- 1. Plants of the new Chrysanthemum were smaller than, more rounded than and not as upright as plants of the cultivar Barbara.
- 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Barbara.
- 3. Ray florets of plants of the new Chrysanthemum were lighter lavender in color than ray florets of plants of the cultivar Barbara.
- 4. Plants of the new Chrysanthemum flowered about one week later than plants of the cultivar Barbara when grown under natural season conditions.
- 5. Plants of the new Chrysanthemum were less sensitive to the pathogen Fusarium than plants of the cultivar Barbara.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Moza Con 02, disclosed in U.S. Plant Pat. No. 14,745. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Moza Con 02 in the following characteristics:
-
- 1. Plants of the new Chrysanthemum were smaller than plants of the cultivar Moza Con 02.
- 2. Ray florets of plants of the new Chrysanthemum had better color retention than ray florets of plants of the cultivar Moza Con 02.
The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yomia’ grown in a container.
The photograph on the second sheet comprises a close-up view of typical inflorescences of the cultivar ‘Yomia’.
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. The following observations and measurements describe plants grown in Leamington, Ontario, Canada during the summer in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. Rooted cuttings were planted in 15.25-cm containers, grown under artificial long day conditions (four-hour night interruption) and pinched about ten days later. About ten days after the pinch, plants were then exposed to artificial short day conditions (11.5 hours light) until flowering. During the production of the plants, temperatures ranged from 18° C. to 38° C. Measurements and numerical values represent averages for typical flowering plants.
