Abstract
A new and distinct cultivar of Poinsettia plant named ‘Duelewi’, characterized by its inflorescences with inflorescences with pale yellow-colored flower bracts; dark green-colored leaves with green-colored petioles; uniform and rounded plant habit; early flowering; large number of cyathia per corymb; and excellent post-production longevity.
Description
Euphorbia pulcherrima Willd. cultivar Duelewi.
The present Invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name ‘Duelewi’.
The new Poinsettia is a product of a mutation induction program conducted by the Inventor in Rheinberg, Germany. The objective of the program is to create new Poinsettia cultivars with uniform plant habit and attractive flower bract coloration.
The new Poinsettia originated by exposing unrooted cuttings of the Euphorbia pulcherrima Willd. cultivar Duewi, disclosed in U.S. Plant Pat. No. 11,334, to gamma radiation in Rheinberg, Germany in 1998. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of irradiated plants in a controlled environment in Rheinberg, Germany in 1998. The selection of this plant was based on its attractive flower bract coloration and uniform plant habit.
Asexual reproduction of the new Poinsettia by vegetative terminal cuttings taken at Rheinberg, Germany since 1998, has shown that the unique features of this new Poinsettia are stable 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 ‘Duelewi’. These characteristics in combination distinguish ‘Duelewi’ as a new and distinct cultivar:
1. Inflorescences with pale yellow-colored flower bracts.
2. Dark green-colored leaves with green-colored petioles.
3. Uniform and rounded plant habit.
4. Early flowering; response time, about eight weeks.
5. Large number of cyathia per corymb.
6. Excellent post-production longevity.
Plants of the new Poinsettia differ primarily from plants of the parent cultivar in flower bract color as plants of the cultivar Duewi had red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the cultivar Fiscor Creme, disclosed in U.S. Plant Pat. No. 10,824. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Poinsettia differed from plants of the cultivar Fiscor Creme in the following characteristics:
1. Plants of the new Poinsettia were more freely branching than plants of the cultivar Fiscor Creme.
2. Plants of the new Poinsettia had larger leaves with longer petioles than plants of the cultivar Fiscor Creme.
3. Plants of the new Poinsettia had smaller flower bracts than plants of the cultivar Fiscor Creme.
4. Flower bract color of plants of the new Poinsettia was not as yellow as flower bract color of plants of the cultivar Fiscor Creme.
5. Plants of the new Poinsettia had larger cyathia clusters and more cyathia per corymb than plants of the cultivar Fiscor Creme.
The accompanying colored photograph illustrates the overall appearance of the new Poinsettia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia. The photograph comprises a side perspective view of a single flowering plant of ‘Duelewi’ grown in a container.
The new Poinsettia has 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, any variance in genotype.
The aforementioned photographs, following observations and averaged measurements describe plants grown in Rheinberg, Germany during the winter under commercial practice in a glass-covered greenhouse with day and night temperatures about 22° C. and light levels about 4,500 lux. Single plants were grown in 13-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 16 weeks from unrooted cuttings when the photographs and the detailed botanical description were taken.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
