Abstract

Disclosed herein is new Viola cornuta plant named ‘Sunvioho’, which is a vegetative propagated variety that was developed by specific hybridization between ‘9V-39a’ and ‘Alpine Sun’. ‘Sunvioho’ has a spreading habit with very long stem. The plant height is low and the branching is abundant. Flowers are vertically oblong and very small. The color of flower is pale yellow green with vivid yellow eye. The plant has a high resistance to rain, cold, pests and diseases.

Description

BOTANICAL/COMMERCIAL CLASSIFICATION: VIOLA CORNUTA/VIOLA PLANT.
Varietal denomination: cv. ‘Sunvioho’.
BACKGROUND OF THE VARIETY
The genus 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 temperate regions worldwide.
Each flower has 5 petals: a spurred lower petal, 2 lateral petals and 2 upward-facing upper petals.
While 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. wittrocklana.
Viola cornuta is stem prostrate, with leaves narrow to broad ovate, base cordate to truncate, and margin shallow-crenate.
The female parent used in the crossing of ‘Sunvioho’ was ‘9V-39a’ (unpatented in the U.S.) which is our breeding line and grown at Omori-cho, Yokaichi-shi, Shiga-ken, Japan
The pollen parent used in the crossing of ‘Sunvioho’ was ‘Alpine Sun’ (a cultivar unpatented in the U.S.).
BREEDING PROCESS
Crossing between ‘9V-39a’ as female parent and ‘Alpine Sun’ as male parent was conducted at Omori-cho, Yokaichi-shi, Shiga-ken, Japan in April 2000. In May, seeds were obtained from the crossing and were sown and grown at the same location. In August, three seedlings were selected in view of having highly spreading habit with white petals from 20 seedlings obtained, and propagated by cutting. Those three seedlings were tested by flower potting and bedding from October 2001, at Omori-cho, Yokaichi-shi, Shiga-ken, Japan. Finally one variety was selected in view of having a long blooming time. The botanical characteristics of that plant were then examined, using similar variety ‘Violetto Nive’ (unpatented in the U.S.) and ‘Alpine Summer’ (unpatented in the U.S.) 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. The new variety of Viola cornuta plant was named ‘Sunvioho’.
Viola cornuta plants, ‘Alpine Sun’ and ‘9V-39a’, are presently maintained at Omori-cho, Yokaichi-shi, Shiga-ken, Japan.
This new and distinct variety of Viola cornuta plant, ‘Sunvioho’, was asexually reproduced by tissue culture at the aforementioned the Omori-cho, Yokaichi-shi, Shiga-ken, Japan and the homogeneity and stability thereof were confirmed.
The new variety reproduces true to type in successive generations of asexual reproduction.
