| Abstract: |
A new and distinct of Chrysanthemum plant named `Rosy Yoigloo`, characterized by its upright, outwardly spreading and mounding plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; duplex-type inflorescences with obovate-shaped ray florets; red-colored ray florets; and natural season flowering about September 18.sup.th in the Northern Hemisphere. |
| Claim: |
It is claimed:
1. A new and distinct Chrysanthemum plant named `Rosy Yoigloo` as illustrated and described. |
| Description: |
Botanical designation:Chrysanthemum.times.morifolium.
Cultivar denomination: `ROSY YOIGLOO`.
Cross-reference to related application: Chrysanthemum Plant Named `Warm Yoigloo`; U.S. Plant patent application Ser. No. 11/705,880; Mark A. Smith, Applicant; filed concurrently.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium, commercially grown as a perennial garden Chrysanthemum and hereinafter referred to by the name `RosyYoigloo`.
The objective of the breeding program is to create new perennial garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum.times.morifolium cultivar Warm Yoigloo, disclosed in a U.S. Plant patent application filed concurrently. The new Chrysanthemum was discovered and selectedby the Inventor as a single flowering plant within a population of plants of the cultivar Warm Yoigloo in December, 2003, in Alva, Fla. The selection of this plant was based on its desirable inflorescence color and good form and substance.
Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in Alva, Fla. in February, 2004. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproducedtrue to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Rosy Yoigloo 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Rosy Yoigloo`. These characteristics in combination distinguish `Rosy Yoigloo` as a new and distinct garden Chrysanthemum cultivar: 1. Upright, outwardly spreading and mounding plant habit. 2. Freely branching habit; dense and full plant habit. 3. Uniform and freely flowering habit. 4. Duplex-type inflorescences with obovate-shaped ray florets. 5. Red-colored ray florets. 6. Natural season flowering about September 18.sup.th in the Northern Hemisphere.
In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the parent, the cultivar Warm Yoigloo, in the following characteristics: 1. Plants of the new Chrysanthemum flowered later than plantsof the cultivar Warm Yoigloo when grown under natural season conditions. 2. Plants of the new Chrysanthemum and the cultivar Warm Yoigloo differed in ray floret color as plants of the cultivar Warm Yoigloo had orange bronze-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar MN 92-333-2, disclosed in U.S. Plant Pat. No. 14,197. In side-by-side comparisons conducted in Alva, Fla. plants of the new Chrysanthemum differed fromplants of the cultivar MN 92-333-2 in the following characteristics: 1. Plants of the new Chrysanthemum were smaller, fuller and more mounted than plants of the cultivar MN 92-333-2. 2. Plants of the new Chrysanthemum had smaller inflorescences withmore ray florets than plants of the cultivar MN 92-333-2. 3. Plants of the new Chrysanthemum flowered ten days earlier than plants of the cultivar MN 92-333-2 when grown under natural season conditions. 4. Ray floret color of plants of the newChrysanthemum did not fade as quickly as ray floret color of plants of the cultivar MN 92-333-2.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 maydiffer slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of `Rosy Yoigloo`.
The photograph at the top of the sheet is a close-up view of typical inflorescences of `Rosy Yoigloo`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Pendleton, S.C. during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercialgarden Chrysanthemum production. During the production of the plants, day temperatures averaged 32.degree. C. and night temperatures averaged 21.degree. C. Plants were grown in 20 cm containers under natural season conditions. Plants used in thephotographs and for the description were about four months old. 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 areused.
