| Abstract: |
A new cultivar of pot chrysanthemum characterized by its single flower form of medium size and white coloration, its abundant production of blooms when grown as a spray pot, its minimal pollen production, its vigorous and upright growth habit with abundant foliage, its nine-week photoperiodic response, and its ability for year around flowering on medium treatment. |
| Claim: |
I claim:
1. A new and distinctive cultivar of chrysanthemum, substantially as herein shown and described, particularly characterized by its single flower form, generally white coloration of theray florets, greenish-yellow coloration of the disc florets, and its very floriferous and vigorous growth habit. |
| Description: |
BACKGROUND OF THE NEW PLANT
My new variety of pot chrysanthemum was selected by me from a population of seedlings resulting from the hybridization of the variety `Bonnie Jean` with the variety `Garland` (U.S. Plant Pat. No. 3,576) with the objective of creating new andunusual varieties. This hybridization was performed by me during March 1976, seeds were then harvested and sown and flowered October 1976. From this population of flowering seedlings, this new plant was selected by me and asexually reproduced under mydirection and further propagated by means of vegetative cuttings. This work was performed in greenhouses at West Chicago, Ill.
Through successive generations of asexual reproduction, this plant has proved that its distinctive characteristics are firmly fixed and hold true from generation to generation.
DESCRIPTION OF THE DRAWINGS
My new chrysanthemum variety is illustrated by the accompanying full color photographic rendition showing the new variety as it appears as a fully grown potted plant, the colors shown being as nearly true as it is reasonably possible to obtain byconventional photographic procedures.
DESCRIPTION OF THE NEW PLANT
The following is a detailed description of my new variety of chrysanthemum, the color designations being according to the R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

Surface texture.--Pubescent.
Peduncle: Sturdy and erect.
Length.--Varies considerably.

THE FLOWER
Response: 9 week.
Recommended flowering: Year around with photoperiodic control.
Bloom:
Type.--Single and composit.
Borne.--A head of many florets borne on a receptacle.
Shape.--Cup-shaped when bloom first opens, becoming almost flat upon maturation.
Size.--Medium-size bloom. Diameter -- Approximately 6.0 to 7.8 cm. Depth -- Approximately 1.3 to 1.8 cm.
Florets: Quantity -- numerous.
Form.--Linear with obtuse apex.
Firmness.--Soft.
Appearance.--Very slight shine.
Color.--Ray florets -- Upper side: 155A, 155B, 155D. Reverse side: 155A, 155B, 155D. Disc florets -- 151A. Discoloration: No change as full bloom ages. Occasional linear yellow (5B, 5C) streaks approximately 0.3 to 1.5 mm. in width appear inray florets.
Persistence: Flowers hang on and dry.
Lasting quality:
On plant.--4 weeks. Not recommended for cut-flower use.
REPRODUCTIVE ORGANS
Stamens:
Quantity.--5 to each disc floret.
Arrangement.--Syngenesious.
Filaments.--Length -- 2 to 4 mm. Color -- yellow.
Pollen.--Color -- yellow.
Pistils:
Number.--One to each ray and disc floret.
Styles.--Length -- 4 to 5 mm.
Stigmas.-- Color -- yellowish-green.
Ovaries: Inferior bicarpellate.
This new variety of chrysanthemum is particularly characterized by its single flower form with creamy white ray florets which occasionally exhibit a yellow streak and disc florets which are initially greenish-yellow, gradually becoming moreyellow as the bloom matures. Disc florets produce very minimal pollen. Ray florets do not reflex upon maturation.
This plant is also characterized by its upright pot habit; its abundant dark green foliage; its very abundant production of blooms when grown as a spray pot; and its ability to be flowered year around, the plant flowering approximately nine weeksfrom the commencement of short-day treatment.
Its primary use is for six-inch, year around pot production.
