Claims
It is claimed:
1. A new and distinct variety of Viola cornuta plant named
`Sunvioki`, substantially as herein illustrated and described.
Description
Botanical/commercial classification: Viola cornuta/Viola Plant.
Varietal denomination: cv. `Sunvioki`.
BACKGROUND OF THE VARIETY
The genus of Viola is included in the family Violaceae, and has
about 500 species of annuals, biennials, evergreen, and
semi-evergreen and deciduous perennials found in varied habitats in
temperature regions worldwide.
Each flower has 5 petals: a spurred lower petal, 2 lateral petals
and 2 upward-facing upper petals.
Many cultivars within the genus are informally referred to as
garden pansies. Violas are all derived from the complex
hybridization of V.tricolour, V.lutea, V.cornuta, and other
species.
Viola cornuta has played an important role in the development of
garden violas and violettas as a result of cross breeding with the
garden pansy, V. wittorockiana.
Viola cornuta is stem prostrate. Leaves are narrow to broad ovate,
base cordate to truncate, margin deeply segmented.
The female parent used in the crossing for obtaining `Sunvioki` was
`9V-39a` (not patented in the United States.
The pollen parent used in the crossing for obtaining of `Sunvioki`
is a commercial cultivar, `Alpine Sun`.
BREEDING PROCESS
Crossing between `9V-39a` as female parent and `Alpine Sun` as male
parent was conducted in Shiga-ken, Japan, in April 2000. In May,
seeds were obtained from the crossing. In August, three seedlings
were selected in view of having highly spreading habit with yellow
petals, and were propagated by cutting. A trial was carried out for
those seedlings by flower potting and bedding from October 2001.
One variety was selected in view of having long blooming time. The
botanical characteristics of that plant were then examined, using
similar varieties `Alpine Spring` and `Violetto Lune` for
comparison. As a result, it was concluded that this Viola cornuta
plant is distinguishable from any other variety, whose existence is
known to us, and uniform and stable in its characteristics. Thenew
variety of Viola cornuta plant was named `Sunvioki`.
This new and distinct variety of Viola cornuta plant, `Sunvioki`,
was asexually reproduced by tissue culture and the homogeneity and
stability thereof were confirmed. The new variety reproduces true
to type in successive generations of asexual reproduction.
Viola cornuta plants, `9V-39a` and `Alpine Sun` are presently
maintained at Shiga-ken, Japan.
