Abstract

A new and distinct cultivar of Poinsettia plant named ‘Dueinfinitywi’, characterized by its upright and outwardly spreading plant habit; freely branching habit; early flowering habit; inflorescences with light yellow-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima.
Cultivar denomination: ‘DUEINFINITYWI’.
BACKGROUND OF THE INVENTION
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 ‘Dueinfinitywi’.
The new Poinsettia is a naturally-occurring whole plant mutation of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number W040, not patented. The cultivar Dueinfinitywi was discovered and selected by the Inventor as a flowering plant within a population of plants of the parent selection in a controlled greenhouse environment in Rheinberg, Germany in December, 2005.
Asexual reproduction of the new Poinsettia by terminal vegetative cuttings in a controlled environment in Rheinberg, Germany since December, 2005, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The cultivar Dueinfinitywi 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dueinfinitywi’. These characteristics in combination distinguish ‘Dueinfinitywi’ as a new and distinct cultivar of Poinsettia:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Early flowering habit.
    • 4. Inflorescences with light yellow-colored flower bracts.
    • 5. Excellent post-production longevity.
In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Poinsettia differed primarily from plants of the parent selection in flower bract coloration as plants of the parent selection had red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the Poinsettia cultivar Elegance White, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Poinsettia differed primarily from plants of the cultivar Elegance White in flower bract color as plants of the new Poinsettia had lighter yellow-colored flowers bracts than plants of the cultivar Elegance White. In addition, plants of the new Poinsettia were more upright in plant habit than plants of the cultivar Elegance White.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of the new Poinsettia. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may 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 typical flowering plant of ‘Dueinfinitywi’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
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. The aforementioned photograph and following observations and measurements describe plants grown in Rheinberg, Germany during the winter in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day and night temperatures averaged 22° C. and light levels were about 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 13-cm containers and were pinched one time about five weeks after planting the cuttings. Plants were about 16 weeks old when the photograph and the detailed description were taken.
