Abstract: A new and distinct cultivar of Chrysanthemum plant named `Yoidea`, characterized by its upright cut Chrysanthemum that is usually grown as a natural spray; dark green-colored foliage; freely flowering habit; uniform inflorescence form and development; large daisy-type inflorescences; bright yellow-colored ray florets; response time about 9.5 weeks; strong peduncles; and good postproduction longevity.
Claim: It is claimed:

1. A new and distinct cultivar of Chrysanthemum plant named `Yoidea`, as illustrated and described.
Description: Botanicaldesignation: Chrysanthemum.times.morifolium.

Cultivar denomination: `Yoidea`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium and hereinafter referred to by the name `Yoidea`.

The new Chrysanthemum 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 cut Chrysanthemum cultivars having inflorescences with desirablecolors and good inflorescence form and substance.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in January, 1998, in Salinas, Calif., of a proprietary selection of Chrysanthemum.times.morifolium identified as code number K062, not patented, as the female, orseed, parent with a proprietary selection of Chrysanthemum.times.morifolium identified as code number K101, not patented, as the male, or pollen, parent.

The cultivar Yoidea was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., in March, 1999. The selection of this plant was based on itsdesirable inflorescence color and good inflorescence form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Alva, Fla. since May, 1999, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yoidea 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 variancein genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Yoidea`. These characteristics in combination distinguish `Yoidea` as a new and distinct cultivar: 1. Upright cut Chrysanthemum that isusually grown as a natural spray. 2. Dark green-colored foliage. 3. Freely flowering habit, about ten inflorescences per flowering stem. 4. Uniform inflorescence form and development. 5. Large daisy-type inflorescences that are about 8.5 cm indiameter. 6. Attractive bright yellow-colored ray florets. 7. Response time about 9.5 weeks. 8. Strong peduncles. 9. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about 17 days in aninterior environment.

Compared to plants of the female parent selection, plants of the new Chrysanthemum have bright yellow-colored ray florets whereas plants of the female parent selection have white-colored ray florets.

Compared to plants of the male parent selection, plants of the new Chrysanthemum have shorter flowering stems, more ray florets per inflorescence and longer peduncles. In addition, plants of the new Chrysanthemum and the male parent selectiondiffer in ray floret coloration as plants of the male parent selection have white-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum.times.morifolium cultivar Arango, disclosed in U.S. Plant Pat. No. 14,619. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemumdiffered from plants of the cultivar Arango in the following characteristics: 1. Plants of the new Chrysanthemum had shorter flowering stems than plants of the cultivar Arango. 2. Plants of the new Chrysanthemum had more uniform flowering than plantsof the cultivar Arango. 3. Plants of the new Chrysanthemum flowered about eight days earlier than plants of the cultivar Arango. 4. Plants of the new Chrysanthemum had shorter peduncles than plants of the cultivar Arango.

BRIEF DESCRIPTION OFTHE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differslightly 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 stem of `Yoidea` grown as a natural spray.

The photograph on the second sheet comprises a close-up view of typical inflorescences of `Yoidea`.

DETAILED BOTANICAL DESCRIPTION

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 aforementioned photographs and followingobservations and measurements describe plants grown in Salinas, Calif., under conditions which approximate commercial practice in a polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Nov. 3, 2004 and received four weeks oflong day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 24 to27.degree. C.; night temperatures, 10 to 16.degree. C.; and light levels, 2,000 to 4,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about ten weeks after the start of shortdays. Botanical classification: Chrysanthemum.times.morifolium cultivar Yoidea. Commercial classification: Daisy-type cut Chrysanthemum. Parentage: Female or seed parent.--Proprietary selection of Chrysanthemum.times.morifolium identified as codenumber K062, not patented. Male or pollen parent.--Proprietary selection of Chrysanthemum.times.morifolium identified as code number K101, not patented. Propagation: Type.--Terminal tip cuttings.
