A new and distinct cultivar of chrysanthemum plant named ‘Yoessex’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored foliage; uniform, freely and early flowering habit; daisy-type inflorescences with purple-colored ray florets and green-colored disc florets; and excellent postproduction longevity.

Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘Yoessex’.
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a pot-type Chrysanthemum and hereinafter referred to by the name ‘Yoessex’.
The new Chrysanthemum is a product of a breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the breeding program is to create new pot-type Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, freely branching habit, good vigor, desirable inflorescence form and floret colors, fast response time and excellent postproduction longevity.
The new Chrysanthemum originated from a cross-pollination made by the Inventor in February 2003, in Salinas, Calif. of a proprietary selection of Chrysanthemum×morifolium identified as code number YB-A2654, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number YB-A2409, 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 in a controlled greenhouse environment in Fort Myers, Fla. in November, 2003.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in a controlled greenhouse environment in Fort Myers, Fla. in February 2004. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
Plants of the new Chrysanthemum 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 variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoessex’. These characteristics in combination distinguish ‘Yoessex’ as a new and distinct pot-type Chrysanthemum cultivar:
Plants of the new Chrysanthemum differ from plants of the female parent selection primarily in ray floret color as plants of the female parent selection have pink-colored ray florets.
Plants of the new Chrysanthemum differ from plants of the male parent selection primarily in ray floret color as plants of the male parent selection have dark pink-colored ray florets. In addition, plants of the new Chrysanthemum do not produce pollen whereas plants of the male parent selection produce pollen.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Yolompoc’, disclosed in U.S. Plant Pat. No. 11,203. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum primarily from plants of ‘Yolompoc’ in the following characteristics:
The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs shows 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 at the bottom of the sheet ‘Yoessex’ grown in a container. The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Yoessex’.
The aforementioned photographs and following observations and measurements describe plants grown in Leamington, Ontario, Canada during the late spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial pot-type Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 24° C., night temperatures ranged from 15° C. to 17° C. and light levels ranged from 4,000 to 6,000 foot candles. Four unrooted cuttings were directly stuck in 15-containers, exposed to long day/short night conditions, and pinched about two weeks later. One week after the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description had been growing for ten weeks and were grown as spray-types. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
