Claims
What is claimed is:
1. A new and distinct cultivar of Petunia plant named `Bluette
Gradation Pink` as herein illustrated and described.
Description
Latin name of the genus and species: Petunia hybrid.
Variety denomination: `Bluette Gradation Pink`.
The new Petunia cultivar resulted as part of a planned breeding
program by the inventor Jun Tsukahara, in Yame, Fukuoka, Japan. The
objective of the breeding program was to develop new Petunia
varieties with interesting colors and attractive plant forms.
The new variety resulted from the crossing of the seed parent, an
unnamed, unpatented proprietary Petunia seedling with the pollen
parent, an unnamed, unpatented proprietary Petunia seedling in
September 2005. The new variety was discovered in November of 2007
by the inventor in a group of seedlings resulting from that
crossing, in a commercial greenhouse in Yame, Fukuoka, Japan.
Asexual reproduction of the new cultivar `Bluette Gradation Pink`
was first performed by vegetative cuttings at a commercial
greenhouse in Yame, Fukuoka, Japan in January 2008. Subsequently
many generations have been produced and have shown that the unique
features of this cultivar are stable and reproduced true to
type.
SUMMARY OF THE INVENTION
The cultivar `Bluette Gradation Pink` has not been observed under
all possible environmental conditions. The phenotype may vary
somewhat with variations in environment such as temperature, day
length and light intensity, without however, any variance in
genotype.
The following traits have been repeatedly observed and are
determined to be the unique characeristics of `Bluette Gradation
Pink`. These characteristics in combination distinguish `Bluette
Gradation Pink` as a new and distinct Petunia cultivar: 1. Unique
pink color with white veins and tube. 2. Trailing plant shape.
COMPARISON TO THE PARENT VARIETIES
Plants of the new cultivar `Bluette Gradation Pink` are similar in
most horticultural characteristics to plants of the unnamed
proprietary seed parent. However, the seed parent has a larger
overall flower size than the new cultivar. Additionally, the seed
parent has thicker diameter stems than `Bluette Gradation
Pink`.
Plants of the new cultivar `Bluette Gradation Pink` are similar in
most horticultural characteristics to plants of the unnamed
proprietary pollen parent. However, the pollen parent has darker
colored flowers, and a smaller overall flower size than the new
cultivar. Additionally, the pollen parent has thinner stems than
the new cultivar.
COMPARISON TO COMMERCIAL VARIETIES
The new cultivar can be compared to the unpatented commercial
variety `Blue Duet Rose`. `Bluette Gradation Pink` is similar to
this commercial variety in most horticultural characteristics,
especially plant habit, however, the new variety has flowers with a
different colored throat and vein, whereas the comparison variety
is all over one solid color.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a
typical plant of `Bluette Gradation Pink` grown in a greenhouse, in
a 6 inch pot. Age of the plant photographed is approximately 12
weeks from a rooted cutting. The photographs were taken using
conventional techniques and although colors may appear different
from actual colors due to light reflectance it is as accurate as
possible by conventional photographic techniques.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The
Royal Horticultural Society Colour Chart except where general terms
