| Abstract: |
A new and distinct cultivar of geranium known by the cultivar name `Tossa` is characterized by a light rose colored flower, a semi-double flower form, medium green foliage with medium zonation, medium flower response in springtime and a compact habit. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of geranium plant known as `Tossa`, as described and illustrated and particularly characterized by a light rose colored flower, a semi-doubleflower form, medium green foliage with medium zonation, medium flower response in springtime and a compact habit. |
| Description: |
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of geranium botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name `Tossa`. `Tossa` is a product of planned breeding program which had the objectiveof creating new geranium cultivars with light rose flower color, semi-double flower form, and medium green foliage. `Tossa` was orignated from a hybridization made in a controlled breeding program in Hagenbach, Germany, in 1991.
The female parent was `Epos`, characterized by its light pink flower color, with red markings, medium green foliage without zonation, semi-double flower form. `Epos` was patented in Germany but is no longer commercially available. `Tossa`differs from `Epos` in terms of their respective flower characterizations as described above. Additionally, the leaves of `Tossa` are zonated whereas the leaves of `Epos` are not. The male parent of `Tossa` was `Laura`, characterized by its pink flowercolor, semi-double flower form, light green foliage without zonation. `Tossa` was discovered and selected as one flowering plant within the progeny of the stated cross by the named inventors in September 1992 in a controlled environment in Hagenbach,Germany.
DESCRIPTION OF THE NEW PLANT
The first act of asexual reproduction of `Tossa` was accomplished when vegetative cuttings were taken from the initial selection in Jan. 1993 in a controlled environment in Hagenbach, Germany, by a technician working under formulationsestablished and supervised by Gerd Endisch.
Horticultural examination of selected units initiated in May 1993 has demonstrated that the combination of characteristics as herein disclosed for `Tossa` are firmly fixed and are retained through successive generations of asexual reproduction.
`Tossa` 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 Hagenbach, Germany, under field conditions which approximate those generally used in commercial practice. The measurements and dimensions given below are approximate.
The following traits have been repeatedly observed and are determined to be basic characteristics of `Tossa` to distinguish this geranium as a new and distinct cultivar:
1. light rose flower color
2. semi-double flower form
3. medium green foliage with medium zonation
4. medium flower response in springtime
5. compact habit
Of the many commercial cultivars known to the present inventor, the most similar in comparison to `Tossa` is `Goesta`. Reference is made to the Chart A below which compares certain characteristics of `Tossa` to those same characteristics of`Goesta`. In comparison to `Goesta`, `Tossa` has a lighter color and a stronger zonation, bigger corolla, shorter peduncle and pedicle length and a more compact habit.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawing show typical flower and foliage characteristics of `Tossa`, with colors being as true as possible with illustrations of this type.
DETAILED BOTANICAL DESCRIPTION
In the following description color references are made to The Royal Horticultural Society Colour Chart (R.H.S.). The color values were determined indoors from plants grown outdoors in August 1994 in Hagenbach, Germany, or Hannover(Bundessortenamt).
