Latest Dummen Jungpflanzenkulturen Patents:
The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium.times.hortorum, known as the variety Duecorre, and hereinafter referred to by the cultivar name HWD Corelli.
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 semi-double geranium with salmon flowers and foliage with a zonation pattern.
The new cultivar originated from a cross made by the inventor of the proprietary selection 85-1-5 as the male or pollen parent with the proprietary selection 85-9-8 as the female or seed parent.
The cultivar HWD Corelli was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Rheinberg, Germany. Asexual reproduction of the new cultivar by terminal cuttings taken 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 Corelli. These characteristics in combination distinguish HWD Corelli as a new and distinct cultivar:
1. Semi-double salmon-orange flowers.
2. Zonation pattern on foliage.
3. Freely branching plant habit.
In comparison to the parent selection 85-1-5, plants of the new Geranium are less vigorous and flowers are larger. In comparison to the parent selection 85-9-8, plants of the new Geranium have a more intense zonation pattern on the foliage, are more vigorous, have smaller flowers, and petal color is salmon and not orange.
The new Geranium is similar in petal color to the patented cultivar Designer Coral (U.S. Plant Pat. No. 8,522) and the cultivar HWD Gabrieli (disclosed in the inventor's pending application). In comparison to plants of the cultivar Designer Coral, plants of the New Geranium have shorter peduncles and a more intense zonation pattern on the foliage. In comparison to plants of the cultivar HWD Gabrieli, plants of the new Geranium have a more orange petal color, are more freely branching, more umbels per plant, fewer flowers per umbel, and longer peduncles.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical potted plant of HWD Corelli with one plant in a 10-cm container.
The cultivar HWD Corelli has not been observed under all possible environmental 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 grown in Rheinberg, Germany, under commercial practice in a glass-covered greenhouse with day temperatures of 24.degree. C. and night temperature of 18.degree. to 20.degree. C. and light levels of 45,000 to 60,000 lux. Plants were grown in 10-cm pots with one plant per pot.
