Abstract

A new and attractive hybrid of Torenia plant, named `Sunrenibu`, attained as selected superior hybrid seedling from a cross involving `Crown Mix`×`Con Color`. The new plant has a less decumbent, more ascending or semi-upright habit, moderate branching and an unusually dense canopy of an attractive mounded form which does not collapse during the season. This plant produces a profusion of flowers of petals and corolla of a nearly monochromatic light purple; and has a high resistance to heat, moderate resistance to pests and diseases and is highly shade tolerant to produce copious flowers from about late June to November, or until killed by frost.

Description

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Torenia plant obtained from crossing "Crown Mix" (♀) and "Con Color" (♂).

The torenia 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 torenia plant which have a semi-erect growth habit, a high resistance to heat and diseases. And the Torenia plant needs full sunshine and hardly grows and has flowers in the shade of trees. Accordingly, this invention was aimed at obtaining a new variety having a great profusion of flowers, vivid purple flower petal with light purple floral tube, semi-erect growth habit, a high resistance to heat and diseases, and growing and having flowers ordinarily in the shade of trees.

The new variety of Torenia plant according to this invention originated from crossing "Con Color" as pollen parent and "Crown Mix" having white flower petals as female parent.

This new variety is an interspecific hybrid from within the genus Torenia.

This plant was originated as a seedling selection from a population of 30 seedlings resulting from the crossing of `Con Color`×`Crown Mix`. The cross was effected in the spring of 1991 in the Plant Biotechnology Laboratory, Institute for Fundamental Research of SUNTORY Ltd., located at 1-1, Wakayamadai 1-chrom, Shimamoto-cho, Mishima-gun, Osaka-fu, Japan. The 30 siblings were forced to a transplant stage in the laboratory, then set out in beds and pots for trials beginning in the fall of 1991. The seedlings were systematically evaluated against the parent varieties for novel and useful traits, leading to the selection and isolation of the subject plant of this invention. In the tests, it has been concluded that this plant has a valuable combination of traits and is distinguishable from all other varieties of Torenia known to us. The plant was then asexually reproduced, by the taking and rooting of cuttings at the location noted above. Clonal progeny from such cuttings were observed to be uniform and stable, and have been identical to the initially selected plant in all distinguishing characteristics. Based on the discovery and testing of this plant, we have determined that this plant not only has a highly desirable shape, plant density, flower size and color characteristics, but has an unusually high tolerance of heat and flowers well in shaded garden conditions. It has been named `Sunrenibu`.

In the following description, the color-coding is in accordance with the Horticultural Color Chart of The Royal Horticultural Society, London, England (R.H.S. Color Chart), and the Inter-Society color Council-Nation Bureau of Standard Color Name (I.S.C.C.-N.B.S. Color Name). A color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.

The female parent used in the crossing of this new variety "Sunrenibu" was "Crown Mix" having white flower petals is one of the Crown Series bred by the Sakata Seed Corp., Japan.
