Claims
It is claimed:
1. A new and distinct Petunia plant named `Sunsurfpiusi` as
illustrated and described.
Description
Botanical designation: Petunia.times.hybrida.
Cultivar denomination: `SUNSURFPIUSI`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Petunia plant, botanically known as Petunia.times.hybrida and
hereinafter referred to by the name `Sunsurfpiusi`.
The new Petunia 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
outwardly spreading Petunia plants with freely branching habit and
attractive flower coloration.
The new Petunia plant originated from a cross-pollination made by
the Inventors in September, 2005 in Higashiomi, Shiga, Japan of a
proprietary selection of Petunia.times.hybrida identified as code
name PxBR, not patented, as the female, or seed, parent with a
proprietary selection of Petunia.times.hybrida identified as code
name Px262-99, not patented, as the male, or pollen, parent. The
new Petunia plant was discovered and selected by the Inventors as a
single flowering plant within the progeny of the stated
cross-pollination in a controlled environment in Higashiomi, Shiga,
Japan in September, 2006.
Asexual reproduction of the new Petunia plant by terminal cuttings
in a controlled environment in Higashiomi, Shiga, Japan since
October, 2006, 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
environmental conditions and cultural conditions. The phenotype may
vary somewhat with variations in environment such as temperature,
daylength 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 `Sunsurfpiusi`.
These characteristics in combination distinguish `Sunsurfpiusi` as
a new and distinct Petunia plant: 1. Compact and mounding plant
habit. 2. Vigorous growth habit. 3. Freely branching habit. 4.
Early and freely flowering habit. 5. Long flowering period. 6.
Medium-sized purple-colored flowers. 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 the following
characteristics: 1. Plants of the new Petunia flower earlier than
plants of the female parent selection. 2. Plants of the new Petunia
have larger flowers than plants of the female parent selection. 3.
Plants of the new Petunia and the female parent selection differ in
flower color as plants of the female parent selection have
darker-colored flowers.
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 male parent selection have lavender-colored flowers.
Plants of the new Petunia can also be compared to plants of the
Petunia `Sunsurfcoparu`, disclosed in U.S. Plant Pat. No. 18,141.
In side-by-side comparisons conducted in Higashiomi, Shiga, Japan,
plants of the new Petunia and `Sunsurfcoparu` differed primarily in
the following characteristics: 1. Plants of the new Petunia had
smaller and darker green-colored leaves than plants of
`Sunsurfcoparu`. 2. Plants of the new Petunia were more freely
flowering than plants of `Sunsurfcoparu`. 3. Plants of the new
Petunia had larger flowers than plants of `Sunsurfcoparu`. 4.
Plants of the new Petunia and `Sunsurfcoparu` differed in flower
color as plants of `Sunsurfcoparu` had red purple-colored flowers.
5. Plants of the new Petunia had larger sepals than plants of
`Sunsurfcoparu`.
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 comprises a side perspective
view of a typical flowering plant of `Sunsurfpiusi` grown in a
container.
The photograph at the bottom of the sheet is a close-up view of a
typical flowering plant of `Sunsurfpiusi`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown during the spring and
early summer in 15-cm containers in an outdoor nursery in
Higashiomi, Shiga, Japan and under commercial practices. During the
production of the plants, day temperatures averaged 23.degree. C.
and night temperatures averaged 13.degree. C. Plants were four
months old when the photographs and description were taken. In the
following description, color references are made to The Royal
Horticultural Society Colour Chart, 2001 Edition, except where
general terms of ordinary dictionary significance are used.
