Claims
It is claimed:
1. A new and distinct Petunia plant named `Sunpetu 761` as
illustrated and described.
Description
Botanical designation: Petunia x hybrida.
Cultivar denomination: `SUNPETU 761`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Petunia plant, botanically known as Petunia x hybrida and
hereinafter referred to by the name `Sunpetu 761`.
The new Petunia plant is a product of a planned breeding program
conducted by the Inventor in Higashiomi, Shiga, Japan. The
objective of the breeding program is to create new vigorous,
trailing and freely-flowering Petunia plants with attractive flower
colors and patterns.
The new Petunia plant originated from a cross-pollination made by
the Inventor in July, 2013 in Higashiomi, Shiga, Japan of a
proprietary selection of Petunia x hybrida identified as code
number MP24-125-2, not patented, as the female, or seed, parent
with a proprietary selection of Petunia x hybrida identified as
code number MP25-125-2, not patented, as the male, or pollen,
parent. The new Petunia plant was discovered and selected by the
Inventor as a single flowering plant within the progeny of the
stated cross-pollination in a controlled greenhouse environment in
Higashiomi, Shiga, Japan in July, 2014.
Asexual reproduction of the new Petunia plant by terminal
vegetative cuttings in a controlled greenhouse environment in
Higashiomi, Shiga, Japan since January, 2015 has shown that the
unique features of this new Petunia plant are stable and reproduced
true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Petunia have not been observed under all possible
combinations of environmental conditions and cultural conditions.
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 `Sunpetu 761`. These
characteristics in combination distinguish `Sunpetu 761` as a new
and distinct Petunia plant: 1. Mounding and trailing plant habit.
2. Vigorous growth habit. 3. Freely branching habit. 4. Freely
flowering habit. 5. Long flowering period. 6. Flowers that are
white in color with a red purple-colored cordate-shaped pattern. 7.
Good garden performance.
Plants of the new Petunia can be compared to plants of the female
parent selection. Plants of the new Petunia differ primarily from
plants of the female parent selection in flower color as plants of
the new Petunia have white-colored flowers with a red
purple-colored cordate pattern whereas plants of the female parent
selection have white-colored flowers with a purple-colored picotee
pattern.
Plants of the new Petunia can be compared to plants of the male
parent selection. Plants of the new Petunia differ primarily from
plants of the male parent selection in flower color as plants of
the new Petunia have white-colored flowers with a red
purple-colored cordate pattern whereas plants of the male parent
selection have white-colored flowers with a light pink-colored
cordate pattern.
Plants of the new Petunia can also be compared to plants of the
Petunia x hybrida `Sunmomoheart`, disclosed in U.S. Plant Pat. No.
28,290. In side-by-side comparisons, plants of the new Petunia and
`Sunmomoheart` differ primarily in the following characteristics:
1. Plants of the new Petunia are more trailing than and not as
mounding as plants of `Sunmomoheart`. 2. Plants of the new Petunia
are broader than plants of `Sunmomoheart`. 3. Leaves of plants of
the new Petunia are darker green than leaves of plants of
`Sunmomoheart`. 4. Plants of the new Petunia are more freely
flowering than plants of `Sunmomoheart`. 5. Flower petals of plants
of the new Petunia are broader than flower petals of plants of
`Sunmomoheart`. 6. Flowers of plants of the new Petunia have a
larger cordate pattern than flowers of plants of
`Sunmomoheart`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Petunia 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 Petunia plant.
The photograph at the top of the sheet (FIG. 1 of 2) is a side
perspective view of a typical flowering plant of `Sunpetu 761`
grown in a container.
The photograph at the bottom of the sheet (FIG. 2 of 2) is a
close-up view of a typical flowering plant of `Sunpetu 761`.
