Claims
It is claimed:
1. A new and distinct Poinsettia plant named `Rineab` as
illustrated and described.
Description
Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: `RINEAB`.
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 cultivar name
`Rineab`.
The new Poinsettia plant is a product of a planned breeding program
conducted by the Inventor in Bonsall, Calif. The objective of the
breeding program is to create new strong, upright and
early-flowering Poinsettia plants having upright flower bracts,
good cyathia development, high temperature tolerance and excellent
post-production longevity.
The new Poinsettia plant originated from a cross-pollination made
by the Inventor in the autumn of 2013 of Euphorbia pulcherrima
Willd. `Dueavared`, disclosed in U.S. Plant Pat. No. 18,627, as the
female, or seed, parent, with Euphorbia pulcherrima Willd.
`PER1360`, disclosed in U.S. Plant Pat. No. 28,222, as the male, or
pollen, parent. The new Poinsettia plant was discovered and
selected by the Inventor as a single flowering plant from within
the progeny of the stated cross-pollination in a controlled
greenhouse environment in Bonsall, Calif. in November, 2014.
Asexual reproduction of the new Poinsettia plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Bonsall, Calif. since the spring of 2015 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 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 `Rineab`. These
characteristics in combination distinguish `Rineab` as a new and
distinct Poinsettia plant: 1. Upright and uniformly mounded plant
habit. 2. Moderately vigorous growth habit. 3. Freely and upright
to somewhat outwardly branching habit with thick and sturdy lateral
branches. 4. Dark green-colored leaves that are oak leaf-shaped. 5.
Early flowering habit; when grown under natural flowering season
conditions plants flower on or about November 28 in Southern
California. 6. Inflorescences with vivid red-colored flower bracts
that are oak leaf-shaped. 7. Good post-production longevity.
In side-by-side comparisons conducted in Bonsall, Calif., plants of
the new Poinsettia differ primarily from plants of the female
parent, `Dueavared`, in the following characteristics: 1. Branch
angle of plants of the new Poinsettia is more upright than and not
as wide as branch angle of plants of `Dueavared`. 2. Plants of the
new Poinsettia have thicker stems than plants of `Dueavared`. 3.
Leaves of plants of the new Poinsettia are broader than leaves of
plants of `Dueavared`. 4. Leaves of plants of the new Poinsettia
are oak leaf-shaped whereas leaves of plants of `Dueavared` are
ovate in shape. 5. Flower bracts of plants of the new Poinsettia
are broader than flower bracts of plants of `Dueavared`. 6. Flower
bracts of plants of the new Poinsettia are oak leaf-shaped whereas
flower bracts of plants of `Dueavared` are ovate in shape. 7.
Flower bracts of plants of the new Poinsettia are lighter red in
color than flower bracts of plants of `Dueavared`.
In side-by-side comparisons conducted in Bonsall, Calif., plants of
the new Poinsettia differ primarily from plants of the male parent,
`PER1360`, in the following characteristics: 1. Plants of the new
Poinsettia are taller than plants of `PER1360`. 2. Branch angle of
plants of the new Poinsettia is more upright than and not as wide
as branch angle of plants of `PER1360`. 3. Leaves of plants of the
new Poinsettia are oak leaf-shaped whereas leaves of plants of
`PER1360` are ovate in shape occasionally with broad lobes. 4.
Flower bracts of plants of the new Poinsettia are oak leaf-shaped
whereas flower bracts of plants of `PER1360` are ovate in shape
occasionally with broad lobes. 5. Flower bracts of plants of the
new Poinsettia are more upright than flower bracts of plants of
`PER1360`. 6. Flower bracts of plants of the new Poinsettia are
lighter red in color than flower bracts of plants of `PER1360`.
Plants of the new Poinsettia can be compared to plants of the
Euphorbia pulcherrima Willd. `Eckanezka`, disclosed in U.S. Plant
Pat. No. 19,192. In side-by-side comparisons, plants of the new
Poinsettia differ primarily from plants of `Eckanezka` in the
following characteristics: 1. Plants of the new Poinsettia are more
upright and taller than plants of `Eckanezka`. 2. Leaves of plants
of the new Poinsettia are broader than leaves of plants of
`Eckanezka`. 3. Leaves of plants of the new Poinsettia are oak
leaf-shaped whereas leaves of plants of `Eckanezka` are ovate to
elliptical in shape. 4. Flower bracts of plants of the new
Poinsettia are oak leaf-shaped whereas flower bracts of plants of
`Eckanezka` are ovate to elliptical in shape. 5. Flower bracts of
plants of the new Poinsettia are lighter red in color than flower
bracts of plants of `Eckanezka`. 6. Plants of the new Poinsettia
are more high temperature tolerant than plants of `Eckanezka`.
Plants of the new Poinsettia can also be compared to plants of the
Euphorbia pulcherrima Willd. `PER1055`, disclosed in U.S. Plant
Pat. No. 15,882. In side-by-side comparisons, plants of the new
Poinsettia differ primarily from plants of `PER1055` in the
following characteristics: 1. Leaves of plants of the new
Poinsettia are oak leaf-shaped whereas leaves of plants of
`PER1055` are elliptical in shape. 2. Flower bracts of plants of
the new Poinsettia are oak leaf-shaped whereas flower bracts of
plants of `PER1055` are elliptical in shape. 3. Flower bracts of
plants of the new Poinsettia are flatter than and not as undulate
as flower bracts of plants of `PER1055`. 4. Flower bracts of plants
of the new Poinsettia are lighter red in color than flower bracts
of plants of `PER1055`.

DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following
detailed description were grown during the spring and summer in
15.25-cm in a polyethylene-covered greenhouses in Bonsall and
Encinitas, Calif. under artificial long nyctoperiod conditions and
cultural practices typical of commercial Poinsettia production.
During the production of the plants, day temperatures averaged
26.degree. C., night temperatures averaged 18.degree. C. and light
levels averaged 4,500 foot-candles. Measurements and numerical
values represent averages for typical flowering plants. Plants were
pinched one time two weeks after planting and were 18 weeks from
unrooted cuttings 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.
