Claims
It is claimed:
1. A new and distinct Catharanthus plant named `Suncatha 2316` as
illustrated and described.
Description
Botanical designation: Catharanthus roseus.
Cultivar denomination: `SUNCATHA 2316`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Catharanthus
plant, botanically known as Catharanthus roseus and hereinafter
referred to by the cultivar name `Suncatha 2316`.
The new Catharanthus plant is a product of a planned breeding
program conducted by the Inventor in Yame, Fukuoka, Japan. The
objective of the breeding program is to develop new freely
branching and vigorous Catharanthus plants with numerous attractive
flowers.
The new Catharanthus plant originated from a cross-pollination
conducted by the Inventor in Yame, Fukuoka, Japan in August, 2011
of a proprietary selection of Catharanthus roseus identified as
code designation S22-P-27, not patented, as the female, or seed,
parent with a proprietary selection of Catharanthus roseus
identified as code designation SIR22-16, not patented, as the male,
or pollen, parent. The new Catharanthus 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 Yame, Fukuoka, Japan in February,
2012.
Asexual reproduction of the new Catharanthus plant by vegetative
tip cuttings in a controlled greenhouse environment in Yame,
Fukuoka, Japan since February, 2012, has shown that the unique
features of this new Catharanthus plant are stable and reproduced
true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Catharanthus 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 `Suncatha 2316`.
These characteristics in combination distinguish `Suncatha 2316` as
a new and distinct Catharanthus plant: 1. Upright to outwardly
spreading and mounding plant habit. 2. Vigorous growth habit. 3.
Freely basal branching habit. 4. Freely flowering habit. 5. Long
flowering period. 6. Double-type flowers that are pale pink in
color. 7. Good garden performance.
Plants of the new Catharanthus can be compared to plants of the
female parent selection. Plants of the new Catharanthus differ
primarily from plants of the female parent selection in flower
petal color as plants of the female parent selection have darker
pink-colored flower petals.
Plants of the new Catharanthus can be compared to plants of the
male parent selection. Plants of the new Catharanthus differ
primarily from plants of the male parent selection in the following
characteristics: 1. Plants of the new Catharanthus have double-type
flowers whereas plants of the male parent selection have
single-type flowers. 2. Plants of the new Catharanthus and the male
parent selection differ in flower color as plants of the male
parent selection have red-colored flowers.
Plants of the new Catharanthus can be compared to plants of the
Catharanthus roseus `Sunnichi Tahome`, disclosed in U.S. Plant Pat.
No. 25,250. In side-by-side comparisons, plants of the new
Catharanthus differed from plants of `Sunnichi Tahome` in the
following characteristics: 1. Plants of the new Catharanthus were
larger than plants of `Sunnichi Tahome`. 2. Plants of the new
Catharanthus had smaller leaves than plants of `Sunnichi Tahome`.
3. Plants of the new Catharanthus had smaller flowers than plants
of `Sunnichi Tahome`. 4. Plants of the new Catharanthus had
double-type flowers whereas plants of `Sunnichi Tahome` had
single-type flowers. 5. Plants of the new Catharanthus and
`Sunnichi Tahome` differed in flower color as plants of `Sunnichi
Tahome` had white-colored flowers with red purple-colored centers.
6. Plants of the new Catharanthus had shorter peduncles than plants
of `Sunnichi Tahome`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Catharanthus 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 Catharanthus plant.
The photograph at the top of the sheet comprises a side perspective
view of a typical flowering plant of `Suncatha 2316` grown in a
container.
The photograph at the bottom of the sheet comprises a close-up view
of a typical flowering plant of `Suncatha 2316`.
