| Abstract: |
A new and distinct cultivar of Chrysanthemum plant named `Sly Yojenna`, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; decorative-type inflorescences with elongated oblong to ligulate-shaped ray florets, red purple-colored ray florets; and natural season flowering about September 26.sup.th in the Northern Hemisphere. |
| Claim: |
It is claimed:
1. A new and distinct Chrysanthemum plant named `Sly Yojenna` as illustrated and described. |
| Description: |
Botanical designation:Chrysanthemum.times.morifolium.
Cultivar denomination: `Sly Yojenna`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium, commercially grown as a garden Chrysanthemum and hereinafter referred to by the name `Sly Yojenna`.
The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum.times.morifolium cultivar Yojenna, disclosed in U.S. Plant Pat. No. 17,532. The new Chrysanthemum was discovered and selected by the Inventor as a singleflowering plant within a population of plants of the parent selection in December, 2003, in Alva, Fla. The selection of this plant was based on its desirable inflorescence color and good form and substance.
Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in Alva., Fla. in February, 2004. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproducedtrue to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Sly Yojenna 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sly Yojenna`. These characteristics in combination distinguish `Sly Yojenna` as a new and distinct garden Chrysanthemum cultivar: 1. Compact, upright and outwardly spreading plant habit. 2. Freely branching habit; dense and full plant habit. 3. Uniform and freely flowering habit. 4. Decorative-type inflorescences with elongated oblong to ligulate-shaped ray florets. 5. Redpurple-colored ray florets. 6. Natural season flowering about September 26.sup.th in the Northern Hemisphere.
In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed primarily from plants of the parent, the cultivar Yojenna, in ray floret color as ray florets of plants of the new Chrysanthemum were more red in colorthan ray florets of plants of the cultivar Yojenna.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yobrandi, disclosed in U.S. Plant Pat. No. 16,134. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed fromplants of the cultivar Yobrandi in the following characteristics: 1. Plants of the new Chrysanthemum were taller and more upright than plants of the cultivar Yobrandi. 2. Plants of the new Chrysanthemum had larger inflorescences than plants of thecultivar Yobrandi. 3. Ray florets of plants of the new Chrysanthemum were lighter red in color than ray florets of plants of the cultivar Yobrandi.
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 maydiffer 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 a typical flowering plant of `Sly Yojenna`.
The photograph at the top of the sheet is a close-up view of typical inflorescences of `Sly Yojenna`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Fletcher, N.C. during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercialgarden Chrysanthemum production. During the production of the plants, day temperatures averaged 29.degree. C. and night temperatures averaged 16.degree. C. Plants were grown in 15-containers, exposed to long day/short night conditions and pinchedabout two weeks later. About two weeks after the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description were about three months old. In the following description, color referencesare made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Botanical classification: Chrysanthemum.times.morifolium cultivar Sly Yojenna.
