A new and distinct cultivar of Chrysanthemum plant named ‘Yoyukon’, characterized by its uniform and upright plant habit; strong growth habit; dark green-colored foliage; uniform flowering response and habit; best grown unpinched and as a disbud-type; early flowering habit; decorative incurve-type inflorescences; white-colored ray florets; and good postproduction longevity with plants maintaining good substance and color for about three weeks in an interior environment.

Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘Yoyukon’.
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 ‘Yoyukon’.
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 program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.
The new Chrysanthemum originated from a cross-pollination made in November, 1999 in Salinas, Calif., of a proprietary selection of Chrysanthemum×morifolium identified as code number YB-4699, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number YB-4976, not patented, as the male, or pollen, parent. 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, 2000. The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Alva, Fla. in March, 2001. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
The cultivar Yoyukon has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoyukon’. These characteristics in combination distinguish ‘Yoyukon’ as a new and distinct Chrysanthemum:
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 primarily in ray floret coloration as plants of the female parent selection have pink-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 primarily in floret formation as plants of the male parent selection have disc florets.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Yokodiak, disclosed in U.S. Plant Pat. No. 11,997. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yokodiak in the following characteristics:
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 differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph of the first sheet comprises a side perspective view of typical flowering plants of ‘Yoyukon’ grown as disbud-types.
The photograph on the second sheet comprises a close-up view of a typical inflorescence of ‘Yoyukon’ grown as disbud-types.
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, following observations and measurements describe plants grown and flowered during the spring in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, the following conditions were measured: day temperatures, 21° C. to 27° C.; night temperatures, 17° C. to 19° C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cm containers and exposed to long day/short night conditions. About two weeks later, the photoinductive short day/long night treatments were initiated. Plants used for the description were grown as disbud-types. Measurements and numerical values represent averages of typical flowering plants.
