Abstract
A new and distinct cultivar of Poinsettia plant named ‘Ecksnow’, characterized by its inflorescences with pale yellow-colored flower bracts; dark green-colored leaves; uniform and mounded plant habit; early flowering; and excellent post-production longevity.
Description
Euphorbia pulcherrima.
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 ‘Ecksnow’.
The new Poinsettia a product of a planned breeding program conducted by the inventor in Encinitas, Calif. The objective of the breeding program is to create new Poinsettia cultivars having flower bracts with desirable colors, uniform plant habit and excellent post-production longevity.
The new Poinsetta is a naturally-occurring whole plant mutation of a unnamed proprietary induced mutation, not patented, that originated by exposing unrooted cuttings of the Euphorbia pulcherrima Willd. cultivar Eckabish, disclosed in U.S. Plant Pat. No. 11,200, to gamma radiation. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of plants of the irradiated selection on or about Jul. 30, 1999, in a controlled environment in Encinitas, Calif.
Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, Calif., since August, 1999, 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 ‘Ecksnow’. These characteristics in combination distinguish ‘Ecksnow’ as a new and distinct cultivar:
1. Inflorescences with pale yellow-colored flower bracts.
2. Dark green-colored leaves.
3. Uniform and mounded plant habit.
4. Early flowering, natural season flower maturity date is November 26 for plants grown in Encinitas, Calif.; response time, about 8.5 weeks.
5. Excellent post-production longevity.
Plants of the new Poinsettia are most similar to plants of the cultivar Eckabish. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of the cultivar Eckabish in the following characteristics:
1. Plants of the new Poinsettia were slightly smaller and not as freely branching as plants of the cultivar Eckabish.
2. Plants of the new Poinsettia had longer leaves than plants of the cultivar Eckabish.
3. Flower bract color of plants of the new Poinsettia was pale yellow whereas flower bract color of plants of the cultivar Eckabish was red.
The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Ecksnow’ grown in a 16.5-cm container.
The photograph at the top of the second sheet comprises a top perspective view of a typical flowering plant of ‘Ecksnow’.
The photograph at the bottom of the second sheet is a close-up view of typical leaves, developing bracts and fully developed flower bracts of ‘Eckabish’ (top) and ‘Ecksnow’ (bottom).
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 Encinitas, Calif. during the winter under commercial practice in a polyethylene-covered greenhouse with day temperatures about 24° C., night temperatures about 19° C., and light levels about 4,000 foot-candles. Single plants were grown in 16.5-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 17.5 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 except where general terms of ordinary dictionary significance are used.
