Title: Chrysanthemum Plant Named ‘Red Yosonoma’U.S. Plant patent application Ser. No. 12/283,269.
Applicant: Wendy R. Bergman.
BACKGROUND OF THE INVENTION
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 ‘Pink Yosonoma’.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar ‘Yosonoma’, disclosed in U.S. Plant Pat. No. 17,860. The new Chrysanthemum was discovered and selected by the Inventor in a controlled greenhouse environment as a single flowering plant within a population of plants of ‘Yosonoma’ in December, 2005, in Fort Myers, Fla.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in a controlled greenhouse environment in Fort Myers, Fla. in March, 2006. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
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 ‘Pink Yosonoma’. These characteristics in combination distinguish ‘Pink Yosonoma’ as a new and distinct pot-type Chrysanthemum cultivar:
- 1. Upright, outwardly spreading and uniformly mounded plant habit.
- 2. Strong and vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark green-colored foliage.
- 5. Uniform, freely and early flowering habit.
- 6. Daisy-type inflorescences with light purple-colored ray florets.
- 7. Excellent postproduction longevity with inflorescences maintaining good substance and color for about five to six weeks in an interior environment.
Plants of the new Chrysanthemum differ from plants of the parent, ‘Yosonoma’, in the following characteristics:
- 1. Plants of the new Chrysanthemum flower more uniformly than plants of ‘Yosonoma’.
- 2. Plants of the new Chrysanthemum and ‘Yosonoma’ differ in ray floret color as plants of ‘Yosonoma’ have darker purple-colored ray florets.
Plants of the new Chrysanthemum differ from plants of Chrysanthemum×morifolium ‘Red Yosonoma’, disclosed in U.S. Plant patent application Ser. No. 12/283,269, primarily in ray floret color as plants of ‘Red Yosonoma’ have cherry red-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Yoroanoke’, disclosed in U.S. Plant Pat. No. 12,906. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum primarily from plants of ‘Yoroanoke’ in the following characteristics:
- 1. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Yoroanoke’.
- 2. Plants of the new Chrysanthemum flowered about one week later than plants of ‘Yoroanoke’.
- 3. Plants of the new Chrysanthemum and ‘Yoroanoke’ differed in ray floret color as plants of ‘Yoroanoke’ had lavender pink-colored ray florets.
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 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 comprises a side perspective view of typical flowering plants of ‘Pink Yosonoma’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Pink Yosonoma’.
DETAILED BOTANICAL DESCRIPTION
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 three weeks later. At the time of the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description had been growing for eleven 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.
