| Abstract: |
A new and distinct cultivar of chrysanthemum plant named Frosty having flat capitulum form, single anemone flower type, white ray floret color, immature lime green to mature pale yellow disc florets, 35-45 mm. diameter across capitulum face, semi-upright branching habit, and its relatively short plant height. |
| Claim: |
We claim:
1. A new and distinct cultivar of chrysanthemum plant named Frosty, as described and illustrated, and particularly characterized by its flat capitulum form, single anemone flower type,white ray floret color, immature lime green to mature pale yellow disc florets, 35-45 mm. diameter across capitulum face, semi-upright branching habit, and its relatively short plant height. |
| Description: |
The present invention comprises a new and distinct cultivar of Chrysanthemum morifolium, Ramat., hereinafter referred to by the cultivar name Frosty.
Frosty is a product of a planned breeding program which had the objective of creating new chrysanthemum cultivars with single anemone capitulum type, flat capitulum form, white ray florets and pale yellow disc florets, 9 week flowering response,and year round commercially acceptable quality for pot mum programs. Such traits in combination were not present in previously available commercial cultivars.
Frosty was originated from a hybridization made in a controlled breeding program in Westfield, Woking England in 1977. The male and female parents are unknown at this time. Frosty was discovered and selected as one flowering plant within theprogeny of the stated parentage by Leonard H. Shoesmith and Peter S. Hesse in November, 1978 in a cotrolled environment in West Chicago, Ill., and given the code name P8-906-WS.
The first act of asexual reproduction of Frosty was accomplished when vegetative cuttings were taken from the initial selection in February, 1979 in a controlled environment in West Chicago, Ill. by a technician working under formulationsestablished and supervised by Leonard H. Shoesmith and Peter S. Hesse. Horticultural examination of selected units initiated March, 1979 has demonstrated that the combination of characteristics as herein disclosed for Frosty are firmly fixed and areretained through successive generations of asexual reproduction.
Frosty has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. The following observations, measurements andcomparisons describe plants grown in West Chicago, Ill. and Parrish, Fla. under greenhouse conditions which approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of Frosty, which in combination distinguish this chrysanthemum as a new and distinct cultivar:
1. Flat capitulum form.
2. Single anemone flower type.
3. The anemone disc florets are more developed and pronounced under low temperature conditions. Under high temperatures they are smaller and less pronounced.
4. White ray floret color.
5. Pale yellow (mature) to lime green (immature) disc florets.
6. Diameter across face of the capitulum 35-45 mm.
7. Relatively short pot plant height of about 225 mm. from edge of pot.
8. Semi-upright branching habit.
Of the many commercial cultivars known to the present inventors, the most similar in comparison to Frosty is Illini Windmill. Reference is made to attached Chart A, which compares certain characteristics of Frosty to those same characteristicsof Illini Windmill. The principal distinguishing characteristic is the much smaller capitulum diameter of Frosty.
The accompanying photographic drawings show typical inflorescence and foliage characteristics of Frosty, with colors being asnearly true as possible with illustrations of this type. Sheet 1 is a color photograph of Frosty. Sheet 2 is a black and white print of a photograph showing an abaxial view of Frosty at various stages of growth.
In the following descriptioncolor references are made to The Royal Horticultural Society Colour Chart. The color values were determined between 8:00-9:00 A.M. on Nov. 17, 1982 under 2000-3000 foot candle light intensity at Parrish, Fla.
