Claims
It is claimed:
1. A new and distinct Poinsettia plant named `PER1188` as
illustrated and described.
Description
Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: `PER1188`.
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 `PER1188`.
The new Poinsettia plant is a product of a planned breeding program
conducted by the Inventor in Encinitas, Calif. The objective of the
breeding program is to create new uniform Poinsettia plants having
large inflorescences with bright red-colored flower bracts, early
season flowering habit and excellent post-production longevity.
The new Poinsettia plant originated from a cross-pollination made
by the Inventor in December, 2003 of a proprietary selection of
Euphorbia pulcherrima Willd. identified as code number 1014, not
patented, as the female, or seed, parent, with a proprietary
selection of Euphorbia pulcherrima Willd. identified as code number
PE2-16, 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
Encinitas, Calif. on Dec. 10, 2004.
Asexual reproduction of the new Poinsettia plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Encinitas, Calif. since January, 2005 has shown that the unique
features of this new Poinsettia plant are stable and reproduced
true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Poinsettia have not been observed under all
possible environmental conditions and cultural practices. 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 `PER1188`. These
characteristics in combination distinguish `PER1188` as a new and
distinct Poinsettia plant: 1. Compact, uniform, upright and mounded
plant habit. 2. Vigorous growth habit. 3. Freely branching habit.
4. Dark green-colored leaves. 5. Early season flowering response;
under natural season conditions, plants flower in early November in
Southern California. 6. Large inflorescences with bright
red-colored flower bracts. 7. Good post-production longevity.
In side-by-side comparisons conducted in Encinitas, Calif., plants
of the new Poinsettia differ primarily from plants of the female
parent in the following characteristics: 1. Plants of the new
Poinsettia are more compact than plants of the female parent
selection. 2. Plants of the new Poinsettia flower about two weeks
earlier than plants of the female parent selection. 3. Flower
bracts of plants of the new Poinsettia are bright red in color
whereas flower bracts of plants of the female parent selection are
dark red in color.
In side-by-side comparisons conducted in Encinitas, Calif., plants
of the new Poinsettia differ primarily from plants of the male
parent in the following characteristics: 1. Flower bracts of plants
of the new Poinsettia are not as smooth as flower bracts of plants
of the male parent selection. 2. Flower bracts of plants of the new
Poinsettia are bright red in color whereas flower bracts of plants
of the male parent selection are dark red in color.
Plants of the new Poinsettia can be compared to plants of the
Euphorbia pulcherrima Willd. `PER2804`, disclosed in U.S. Plant
Pat. No. 19,295. In side-by-side comparisons conducted in
Encinitas, Calif., plants of the new Poinsettia differed primarily
from plants of `PER2804` in the following characteristics: 1.
Plants of the new Poinsettia had darker green-colored leaves than
plants of `PER2804`. 2. Plants of the new Poinsettia flowered about
five days later than plants of `PER2804`. 3. Inflorescences of
plants of the new Poinsettia had fewer cyathia than inflorescences
of plants of `PER2804`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 at the bottom of the sheet comprises a side
perspective view of a typical flowering plant of `PER1188` grown in
a container.
The photograph at the top of the sheet is a close-up view of a
typical inflorescence of `PER1188`.
DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following
description were grown during the winter in 16.5-cm containers in a
polyethylene-covered greenhouse in Encinitas, Calif. and under
natural season conditions and cultural practices which approximate
those generally used in commercial Poinsettia production. During
the production of the plants, day temperatures ranged from
20.degree. C. to 27.degree. C., night ranged from 15.degree. C. to
20.degree. C. and light levels ranged from 3,000 to 4,000
foot-candles. Measurements and numerical values represent averages
for typical flowering plants. Plants were pinched one time and were
19 weeks old when the photographs and the description were taken.
In the following description, color references are made to The
Royal Horticultural Society Colour Chart, 2007 Edition, except
where general terms of ordinary dictionary significance are used.
