Claims
It is claimed:
1. A new and distinct Mandevilla plant named `Sunpa 6173` as
illustrated and described.
Description
Botanical designation: Mandevilla hybrida.
Cultivar denomination: `SUNPA 6173`.
STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTORS/APPLICANTS
& ASSIGNEE
The Inventors/Applicants and Assignee assert that no publications
nor advertisements relating to sales, offers for sale or public
distribution occurred more than one year prior to the effective
filing date of this application. Any information about the claimed
plant would have been obtained from a direct or indirect disclosure
from the Inventors/Applicants and/or Assignee. Inventors/Applicants
and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1)
for disclosure and/or sales prior to the filing date but less than
one year prior to the effective filing date.
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 6173`.
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 upright and
freely branching Mandevilla plants with freely flowering habit and
attractive flowers.
The new Mandevilla plant originated from a cross-pollination
conducted by the Inventors in Higashiomi, Shiga, Japan in October,
2014 of a proprietary selection of Mandevilla hybrida identified as
code number 13M-41-7, not patented, as the female, or seed parent
with a proprietary selection of Mandevilla hybrida identified as
code number M37-1, not patented, as the male, or pollen, parent.
The new Mandevilla plant was discovered and selected by the
Inventors 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, 2016.
Asexual reproduction of the new Mandevilla plant by terminal
vegetative cuttings in Higashiomi, Shiga, Japan since March, 2017
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 repeatedly observed and are
determined to be the unique characteristics of `Sunpa 6173`. These
characteristics in combination distinguish `Sunpa 6173` as a new
and distinct Mandevilla plant: 1. Upright plant habit. 2. Vigorous
growth habit. 3. Freely branching habit. 4. Early and freely
flowering habit. 5. Long flowering period. 6. Medium-sized
red-colored flowers with orangish yellow-colored centers.
Plants of the new Mandevilla can be compared to plants of the
female and male parent selections. Plants of the new Mandevilla
differ primarily from plants of the parent selections in plant
habit as plants of the new Mandevilla are upright whereas plants of
the parent selections are semi-upright.
Plants of the new Mandevilla can be compared to plants of the
Mandevilla atroviolacea X (Mandevilla amabilis x M. boliviensis)
`Sunmandecrim`, disclosed in U.S. Plant Pat. No. 15,539. In
side-by-side comparisons, plants of the new Mandevilla differ from
plants of `Sunmandecrim` in the following characteristics: 1.
Plants of the new Mandevilla have shorter internodes than plants of
`Sunmandecrim`. 2. Leaves of plants of the new Mandevilla are
decussate whereas leaves of plants of `Sunmandecrim` are opposite.
3. Plants of the new Mandevilla flower earlier than plants of
`Sunmandecrim`. 4. Plants of the new Mandevilla have smaller
flowers than plants of `Sunmandecrim`. 5. Petals of plants of the
new Mandevilla are not imbricate whereas petals of plants of
`Sunmandecrim` are imbricate. 6. Petals of plants of the new
Mandevilla are lighter red in color than petals of plants of
`Sunmandecrim`.
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 at the top of the sheet (FIG. 1) is a side
perspective view of a typical flowering plant of `Sunpa 6173` grown
in a container.
The photograph at the bottom of the sheet (FIG. 2) is a close-up
view of a typical flower of `Sunpa 6173`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the late
summer in 15-cm containers in an outdoor nursery in Higashiomi,
Shiga, Japan and under cultural practices typical of commercial
Mandevilla 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
Chart, 2015 Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification:
