Description
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of
petunia plant obtained from the crossing of one petunia plant
(.female.), which was selected from a crossing a wild type of
petunia plant called "A1" (.female.) native to Brazil and the other
wild type of petunia plant called "B2" (.male.), and the wild type
of petunia plant called "B2" (.male.).
The petunia is a very popular plant and is used for flower bedding
and potting in the summer season. There are only a few varieties of
the petunia plant which do not have an upright growth habit and
which have a high resistance to rain, heat, cold, and diseases. The
petunia which we previously filed, i.e., the "Revolution" series
[(Revolution Purplepink (U.S. Plant Pat. No. 6,915). Revolution
Brilliantpink (U.S. Plant Pat. No. 6,914). Revolution
Brilliantpink-mini (U.S. Plant Pat. No. 6,899)] is decumbent type
plant having long stems, a lower plant height, abundant branching,
and a high resistance to heat, cold and rain. However, there are
only a few varieties having a great profusion of flowers, vivid
purple color and very small flower and a high resistance to rain,
heat, cold and diseases. Accordingly, this invention was aimed at
obtaining a new variety having a vivid purple color and very small
flower, together with the above features.
The new variety of petunia plant according to this invention
originated from crossing one petunia plant (.female.), which was
selected from a crossing a wild type of petunia plant called "A1"
(.female.) native to Brazil and the other wild type of petunia
plant called "B2" (.male.), and the wild type of petunia plant
called "B2" (.male.).
First of all, 250 seedling were obtained from crossing a wild type
of petunia plant called "A1" native to Brazil as female parent and
the other wild type of petunia plant called "B2" as pollen parent
in May, 1992. From this crossing 5 seedlings were selected in view
of decumbent habit and flower color. And then 300 seedlings were
obtained from a crossing of these selected 5 seedlings as female
parent and the other wild type of petunia plant called "B2" as
pollen parent in Jan., 1993. These 300 seedling were grown and 10
seedlings were selected from these. These selected 10 seedlings
were carried out a trial by flower potting and bedding, and then
the 2 plant selected in summer, 1993. The botanically
characteristics of the finally-selected 2 plants were then
examined, using similar variety "Pearl Sky Blue" for comparison,
from summer, 1993 to autumn, 1994. Finally the only one petunia
plant was selected in Oct. 1995. As a result, it was concluded that
this petunia is distinguishable from any other variety, whose
existence is known to us, sufficiently uniform and stable in its
characteristics, then this new variety of petunia plant was named
"Sunbelkubu".
In the following description, the color-coding is in accordance
with The Horticultural Colour Chart of The Royal Horticultural
Society, London, England (R.H.S. Colour Chart), and the
Inter-Society colour Council-Nation Bureau of Standard Colour Name
(I.S.C.C.-N.B.S. Colour Name). A colour chart based on The Japan
Colour Standard for Horticultural Plant (J.H.S. Colour Chart) is
also added for reference.
The female parent use in the crossing of "Sunbelkubu" was a wild
type of petunia plant called "A1" (.male.) native to Brazil, the
seeds of which were gathered at Gramado, Rio Grande Do Sul, Brazil
and introduced to Japan in December, 1989. The petunia plant "A1"
having a decumbent habit plant having long stems, an over-abundant
branching, great profusion blooms, flowers are single and small,
the petals having a reddish purple color, leaf shape is elliptic,
and a high resistance to rain, heat, drought and pest.
The pollen parent use in the crossing of "Sunbelkubu" was other
wild type of petunia plant called "B2" (.male.) native to Brazil,
the seeds of which were gathered at Gramado. Rio Grande Do Sul.
Brazil and introduced to Japan in December, 1992. The petunia plant
"B2" having a decumbent habit plant having long stems, an
over-abundant branching, great profusion blooms, flowers are single
and small, the petals having a strong bluish purple, leaf shape is
lanceolate, and a high resistance to rain, heat, drought and pest.
These wild type of petunia plants "A1" and "B2" are presently
maintained at the Plant Biotechnology Laboratory of Suntory Ltd.,
residing at 863-1, Aza-Iketani, Oomori-cho, Youkaiti-shi,
Shiga-ken, Japan.

This new and distinct variety of petunia plant, "Sunbelkubu", was
asexually reproduced by cutting at the aforementioned the Plant
Biotechnology Laboratory of Suntory Ltd., and the homogeneity and
stability thereof were confirmed.
SUMMARY OF THE VARIETY
The new variety of petunia plant has a decumbent habit, long stems
and vivid purple flower petal and thus is very different from a
similar variety, "Pearl Sky Blue". The plant has decumbent habit,
over-abundant branching and great profusion blooms, and the whole
bush remains in bloom for a considerable period of time. Especially
secondary braching is strong. The flower are single and very small,
which is clearly distinguished from small flower of "Pearl Sky
Blue" and the petals having a vivid purple, which is clearly
distinguished from strong bluish purple of "Pearl Sky Blue", The
bottom color of the corolla throat is bright greenish yellow and
the outside color of corolla tube is pale yellow green. The plant
has a high resistance to rain, heat, drought and pest.
