| Abstract: |
A new plant variety of Chrysanthemum producing pink flowers with coral centers. |
| Claim: |
What is claimed is:
1. A new and distinct Chrysanthemum plant of the variety substantially as herein shown and described. |
| Description: |
BACKGROUNDOF THE INVENTION
The present invention is directed to a new and distinct variety of Chrysanthemum botanically classified as Dendranthema grandiflora. The varietal denomination of the new Chrysanthemum is `Rosella`.
The female parent of the new variety is the variety known as `Subito` and the male parent is an undistributed, unnamed seedling identified as `G34C7`. The new variety has been asexually reproduced by vegatative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
`Rosella` is a pot type Chrysanthemum plant variety that produces pink flowers with a coral center and a compact growth habit.
COMPARISON WITH PARENT
`Rosella` differs from the female parent in producing flowers of different color.
BRIEF DESCRIPTION OF ILLUSTRATIONS
The accompanying photographs show flowers on a plant of a typical specimen of the new variety with colors being as nearly true as possible with illustrations of this type.
FIG. 1 is a whole plant view of the new cultivar grown in a pot.
FIG. 2 is a closer view, showing inflorescence and foliage characteristics of the new cultivar in greater detail.
DESCRIPTION OF THE PLANT
The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif., in the month of October. `Rosella` has not been observed under all possible environmental conditions. The phenotype may vary withvariations in the environment such as temperature, light intensity, day length and cultural conditions. The color designations herein are from The Royal Horticultural Society Colour Chart except where general terms are used.
To produce a commercial product the plants may be pinched once ten days after planting which results in about 3 to 4 breaks per pinch. It has been observed that the shelf life of `Rosella` is about 23 days with the response time of about 7weeks. No treatment with growth retardant is required. Useful growing conditions include night temperatures of about 64.degree.-66.degree. F., day temperatures of about 80.degree.-85.degree. F. and about 5,000 foot-candles of light.
