Claims
What is claimed is:
1. A new and distinct cultivar of Petunia plant named `Kirimaji
Double Blue Velvet`, substantially as herein shown and described.
Description
Latin name of genus and species of plant claimed:
Petunia.times.hybrida.
Variety denomination: `Kirimaji Double Blue Velvet`.
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 cultivar name `Kirimaji Double Blue
Velvet`.
The new cultivar originated in a controlled breeding program in
Tochigi, Japan during March 2003. The objective of the breeding
program was the development of new double-type Petunia cultivars
have a strong, spreading growth habit and attractive flower
coloration.
The female (seed) parent of the new cultivar was the unnamed
proprietary Petunia.times.hybrida breeding selection, not patented,
characterized by its single-type, dark purple-colored flowers, dark
green-colored foliage, and low mounded, cascading growth habit. The
male (pollen) parent of the new cultivar was `Petudre Violet`, not
patented, characterized by its semi-double type, violet-colored
flowers, medium green-colored foliage, and medium mounded,
cascading growth habit. The new Petunia was discovered and selected
as a single flowering plant within the progeny of the above stated
cross-pollination during October 2003 in a controlled environment
at Tochigi, Japan.
Asexual reproduction of the new cultivar by terminal stem cuttings
since October 2003 at Tochigi, Japan and West Chicago, Ill. has
demonstrated that the new cultivar reproduces true to type with all
characteristics, as herein described, firmly fixed and retained
through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been
repeatedly observed and can be used to distinguish `Kirimaji Double
Blue Velvet` as a new and distinct cultivar of Petunia plant: 1.
Double-type, dark violet-colored flowers; 2. Medium green-colored
foliage; 3. Excellent branching characteristic; and 4. Vigorous,
low mounded, and cascading growth habit.
Plants of the new cultivar differ from plants of the female parent
primarily in flower type and foliage color and from plants of the
male parent primarily in flower type and growth habit.
Of the many commercially available Petunia cultivars known to the
inventors, the most similar in comparison to the new cultivars is
`Kirimaji Double Purple`, U.S. Plant Pat. No. 14,283. However, in
side by side comparisons, plants of the new cultivar differ from
plants of `Kirimaji Double Purple` in the following
characteristics: 1. Plants of the new cultivar are shorter and
wider than plants of `Kirimaji Double Purple`; 2. Plants of the new
cultivar have more and larger flowers than plants of `Kirimaji
Double Purple`; 3. Plants of the new cultivar have more branches
than plants of `Kirimaji Double Purple`; and 4. Plants of the new
cultivar have a different flower color from plants of `Kirimaji
Double Purple`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is
reasonably possible to make the same in color illustrations of this
type, typical flower and foliage characteristics of the new
cultivar. Colors in the photographs differ slightly from the color
values cited in the detailed description, which accurately
describes the colors of `Kirimaji Double Blue Velvet`. The plants
were grown in 10 cm pots for 11 weeks in a greenhouse at West
Chicago, Ill.
FIG. 1 illustrates a side view of the overall growth and flowering
habit of `Kirimaji Double Blue Velvet`.
FIG. 2 illustrates a close-up view of an individual flower of
`Kirimaji Double Blue Velvet`.
DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible
environmental conditions to date. Accordingly, it is possible that
the phenotype may vary somewhat with variations in the environment,
such as temperature, light intensity, and day length, without,
however, any variance in genotype.
The chart used in the identification of colors described herein is
The R.H.S. Colour Chart of The Royal Horticultural Society, London,
England, 2001 edition, except where general color terms of ordinary
significance are used. The color values were determined on Sep. 6,
2005 between 3:00 p.m. and 4:00 p.m. under natural light
conditions, in West Chicago, Ill.
The following descriptions and measurements describe plants
produced from cuttings taken from stock plants and grown in a
double polycarbonate-covered greenhouse under conditions comparable
to those used in commercial practice. The plants were grown at West
Chicago, Ill. in 10 cm pots for 11 weeks utilizing a soilless
growth medium. Greenhouse temperatures were maintained at
approximately 58.degree. F. to 75.degree. F. (14.degree. C. to
24.degree. C. during the day and approximately 52.degree. F. to
62.degree. F. (11.degree. C. to 17.degree. C.) during the night.
Greenhouse light levels of 5,000 to 8,000 footcandles were
maintained during the day. Botanical classification:
