Claims
It is claimed:
1. A new and distinct cultivar of Mandevilla plant named
`Sunmandecrikin`, as illustrated and described.
Description
Botanical designation: Mandevilla hybrid.
Cultivar denomination: `Sunmandecrikin`.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Mandevilla plant, botanically known as Mandevilla hybrid, and
hereinafter referred to by the name `Sunmandecrikin`.
The new cultivar is a product of a planned breeding program
conducted by the Inventors in Higashiomi, Shiga, Japan. The
objective of the breeding program was to develop new Mandevilla
cultivars with glossy leaves and attractive flower form and
coloration.
The new cultivar originated from a cross-pollination made by the
Inventors in June, 2001 of the Mandevilla hybrid cultivar
Sunmandeho, disclosed in U.S. Plant Pat. No. 11,556, as the female,
or seed, parent with a proprietary Mandevilla hybrid selection
identified as code number M38-1, not patented, as the male, or
pollen, parent. The new cultivar was discovered and selected by the
Inventors as a flowering plant within the progeny from this
cross-pollination in a controlled environment in Higashiomi, Shiga,
Japan.
Asexual reproduction of the new cultivar by terminal cuttings in
Higashiomi, Shiga, Japan, since October, 2004, has shown that the
unique features of this new Mandevilla are stable and reproduced
true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Sunmandecrikin have not been observed under
all possible environmental conditions. The phenotype may vary
somewhat with variations in environment 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 `Sunmandecrikin`.
These characteristics in combination distinguish `Sunmandecrikin`
as a new and distinct cultivar: 1. Upright and vigorous vining
growth habit. 2. Glossy and narrowly elliptic leaves. 3. Freely
branching and flowering habit. 4. Large red-colored flowers with
imbricate petals. 5. Long flowering period.
Plants of the new Mandevilla can be compared to plants of the
female parent, the cultivar Sunmandeho. In side-by-side comparisons
conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla
differed from plants of the cultivar Sunmandeho in the following
characteristics: 1. Plants of the new Mandevilla had longer leaves
than plants of the cultivar Sunmandeho. 2. Plants of the new
Mandevilla and the cultivar Sunmandeho differed in flower color as
plants of the cultivar Sunmandeho had white-colored flowers.
Plants of the new Mandevilla can be compared to plants of the male
parent, the proprietary selection identified as M38-1. In
side-by-side comparisons conducted in Higashiomi, Shiga, Japan,
plants of the new Mandevilla differed from plants of the male
parent selection in the following characteristics: 1. Plants of the
new Mandevilla had broader leaves than plants of the male parent
selection. 2. Plants of the new Mandevilla were more tolerant to
high temperatures than plants of the male parent selection.
Plants of the new Mandevilla can be compared to plants of the
Mandevilla cultivar, `Sunmandecos`, disclosed in U.S. Plant Pat.
No. 15,202. In side-by-side comparisons conducted in Higashiomi,
Shiga, Japan, plants of the new Mandevilla differed from plants of
the cultivar Sunmandecos in the following characteristics: 1.
Plants of the new Mandevilla had longer lateral branches and longer
internodes than plants of the cultivar Sunmandecos. 2. Plants of
the new Mandevilla had narrower leaves than plants of the cultivar
Sunmandecos. 3. Plants of the new Mandevilla had slightly smaller
flowers than plants of the cultivar Sunmandecos. 4. Plants of the
new Mandevilla and the cultivar Sunmandecos differed in flower
coloration as plants of the cultivar Sunmandecos had light red
purple-colored flowers. 5. Plants of the new Mandevilla flowered
for a longer period of time than plants of the cultivar
Sunmandecos.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new cultivar, 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 Mandevilla.
The photograph at the top of the sheet comprises a side perspective
view of a typical flowering plant of `Sunmandecrikin`.
The photograph at the bottom of the sheet is a close-up view of
typical flowers of `Sunmandecrikin`.
