| Abstract: |
A new and distinct cultivar of Geranium plant named HWD Ravelina, characterized by its single pink and red bicolor flowers; numerous umbels per plant; freely branching plant habit; and dark green leaves. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Geranium plant named HWD Ravelina, as illustrated and described. |
| Description: |
The presentinvention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium.times.hortorum, known as the variety Duerav, and hereinafter referred to by the cultivar name HWD Ravelina.
The new cultivar is a product of a planned breeding program conducted by the inventor in Rheinberg, Germany. The objective of the breeding program was to develop a new freely-branching single-flowered geranium with pink and red bicolor flowers.
The new cultivar originated from a cross made by the inventor of the nonpatented cultivar Duecon as the male or pollen parent with the patented cultivar Fisrix (U.S. Pat. No. P.P. 7,422) as the female or seed parent.
The cultivar HWD Ravelina was discovered and selected by the inventor as a flowering plant within the progency of the stated cross in a controlled environment in Rheinberg, Germany. Asexual reproduction of the new cultivar by terminal cuttingstaken at Rheinberg, Germany, has shown that the unique features of this new Geranium are stabilized and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of HWD Ravelina. These characteristics in combination distinguish HWD Ravelina as a new and distinct cultivar:
1. Single pink and red bicolor flowers.
2. Numerous umbels per plant.
3. Freely branching plant habit.
4. Dark green leaves.
In comparison to the parent cultivar Duecon, plants of the new Geranium have single (not semi-double) flowers, bicolor and darker petal color, and darker green foliage color. In comparision to the parent cultivar Fistrix, plants of the newGeranium have larger bright red marks on the petals and plants are much more freely branching.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible toobtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical potted plant of HWD Ravelina with one plant in a 10-cm container.
The cultivar HWD Ravelina has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grownin Rheinberg, Germany, under commercial practice in a glass-covered greenhouse with day temperatures of 24.degree. C. and night temperatures of 18.degree. to 20.degree. C. and light levels of 45,000 to 60,000 lux. Plants were grown in 10-cm pots withone plant per pot.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
