Abstract
A new and distinct cultivar of Poinsettia plant named ‘Q103’, characterized by its compact, upright and uniformly mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; large and full inflorescences with numerous light orange to yellow orange-colored flower bracts; and excellent post-production longevity.
Description
Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: ‘Q103’.
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 ‘Q103’.
The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Sabro, Denmark. The objective of the breeding program is to create uniform and freely-branching Poinsettia plants with attractive inflorescences and good postproduction longevity.
The new Poinsettia plant originated from a cross-pollination made by the Inventor in August, 2015 in Sabro, Denmark of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 11_13, not patented, as the female, or seed, parent with a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 2012-0099, not patented, as the male, or pollen, parent. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Sabro, Denmark in May, 2016.
Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Sabro, Denmark since September, 2016 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.
Plants of the new Poinsettia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Q103’. These characteristics in combination distinguish ‘Q103’ as a new and distinct Poinsettia plant:
-
- 1. Compact, upright and uniformly mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark green-colored leaves.
- 5. Large and full inflorescences with numerous light orange to yellow orange-colored flower bracts.
- 6. Excellent post-production longevity.
Plants of the new Poinsettia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of the female parent selection in flower bract color as flower bracts of plants of the female parent selection are yellow in color.
Plants of the new Poinsettia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of the male parent selection in flower bract color as flower bracts of plants of the male parent selection are lighter yellow orange in color.
Plants of the new Poinsettia can also be compared to plants of Euphorbia pulcherrima Willd. ‘NPCW10164’, disclosed in U.S. Plant Pat. No. 22,597. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of ‘NPCW10164’ in the following characteristics:
-
- 1. Plants of the new Poinsettia are more freely branching than plants of ‘NPCW10164’.
- 2. Flower bracts of plants of the new Poinsettia are slightly shorter than flower bracts of plants of ‘NPCW10164’.
- 3. Flower bracts of plants of the new Poinsettia are light orange to yellow orange in color whereas flower bracts of plants of ‘NPCW10164’ are red in color.
The accompanying photographs illustrate the overall appearance of the new Poinsettia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia plant.
The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Q103’ grown in a container.
The photograph at the top of second sheet is a close-up view of a typical dissected inflorescence of ‘Q103’.
The photograph at the bottom of second sheet is a close-up view of the lower and upper surfaces of typical leaves of ‘Q103’.
The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in 13-cm containers in a glass-covered greenhouse in Sabro, Denmark and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 19° C. to 21° C. and light levels ranged from 40 to 50 klux. Plants were pinched one time eight weeks after planting and plants were 20 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
