Claims
It is claimed:
1. A new and distinct Mandevilla plant named `Sunpa 2671` as
illustrated and described.
Description
Botanical designation: Mandevilla hybrida.
Cultivar denomination: `SUNPA 2671`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Mandevilla plant, botanically known as Mandevilla hybrida and
hereinafter referred to by the name `Sunpa 2671`.
The new Mandevilla plant is a product of a planned breeding program
conducted by the Inventors in Higashiomi, Shiga, Japan. The
objective of the breeding program is to create new freely branching
Mandevilla plants with freely flowering habit and attractive
flowers.
The new Mandevilla plant originated from a cross-pollination in
Higashiomi, Shiga, Japan in May, 2013 of a proprietary selection of
Mandevilla hybrida identified as code number 09M111-1, not
patented, as the female, or seed parent with a proprietary
selection of Mandevilla hybrida identified as code number
09M111-1self-1, not patented, as the male, or pollen, parent. The
new Mandevilla 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
Higashiomi, Shiga, Japan in September, 2014.
Asexual reproduction of the new Mandevilla plant by terminal
vegetative cuttings in Higashiomi, Shiga, Japan since March, 2015
has shown that the unique features of this new Mandevilla plant are
stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Mandevilla 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 and light intensity
without, however, any variance in genotype.
The following traits have been repcatedly observed and are
determined to be the unique characteristics of `Sunpa 2671`. These
characteristics in combination distinguish `Sunpa 2671` as a new
and distinct Mandevilla plant: 1. Climbing plant habit. 2. Vigorous
growth habit. 3. Freely branching habit. 4. Early and freely
flowering habit. 5. Long flowering period. 6. Medium-sized
yellow-colored flowers with yellow orange-colored throats.
Plants of the new Mandevilla can be compared to plants of the
female parent selection. Plants of the new Mandevilla differ
primarily from plants of the female parent selection in flower
color as plants of the new Mandevilla have yellow-colored flowers
with yellow orange-colored throats whereas plants of the female
parent selection have pale yellowish pink-colored flowers.
Plants of the new Mandevilla can be compared to plants of the male
parent selection. Plants of the new Mandevilla differ primarily
from plants of the male parent selection in flower color as plants
of the new Mandevilla have yellow-colored flowers with yellow
orange-colored throats whereas plants of the male parent selection
have soft pink-colored flowers.
Plants of the new Mandevilla can be compared to plants of the
Mandevilla hybrida `Sunpapri`, disclosed in U.S. Plant Pat. No.
28,277. In side-by-side comparisons, plants of the new Mandevilla
differ from plants of `Sunpapri` in the following characteristics:
1. Plants of the new Mandevilla have shorter internodes than plants
of `Sunpapri`. 2. Plants of the new Mandevilla have smaller leaves
with shorter petioles than plants of `Sunpapri`. 3. Plants of the
new Mandevilla have smaller flowers than plants of `Sunpapri`. 4.
Plants of the new Mandevilla and `Sunpapri` differ in flower color
as plants of the new Mandevilla have yellow-colored flowers with
yellow orange-colored throats whereas plants of `Sunpapri` have
light to pale orange-colored flowers with orange-colored
throats.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Mandevilla 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 actual colors of the new Mandevilla
plant.
The photograph on the first sheet comprises a side perspective view
of a typical flowering plant of `Sunpa 2671` grown in a
container.
The photograph on the second sheet is a close-up view of typical
flowers and flower buds of `Sunpa 2671`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the summer in
15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan

production. During the production of the plants, day temperatures
averaged 25.degree. C. and night temperatures averaged 15.degree.
C. Plants were six months old when the photographs and detailed
description were taken. In the following description, color
references are made to The Royal Horticultural Society Colour

dictionary significance are used. Botanical classification:
