Description

Botanical/commercial classification: Torenia hybrid/Torenia Plant.
Varietal denomination: CV. ‘Sunrenilapa’.
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Torenia plant that was obtained from the artificial chromosome doubling of ‘Sunrenirirepa’ (Torenia hybrid), obtained by colchicine solution treatment (“artificial doubling”).
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 that have a semi-erect growth habit, medium branching, and a great profusion of blooms.
Accordingly, this invention was aimed at obtaining a new variety having large globose form flowers, strong purplish-red with moderate purplish-pink petals, a semi-erect growth habit, medium branching and a great profusion of blooms.
The new variety of the Torenia plant of this invention originated from the artificial doubling of ‘Sunrenirirepa’ that was previously filed in Japan and the United States of America.
In September 1998, the cuttings of ‘Sunrenirirepa’ were treated with 0.1% colchicines solution, which were propagated by the use of cuttings on the peat at Yokaichi, Shiga, Japan. After two months, some survived plantlets were transplanted in pots. In December 1998, colchiploids were obtained from the cultivation. The discovered Torenia plants were propagated by the use of cuttings and then grown in beds and pots on trial. The botanical characteristics of the plants were examined using the parent variety ‘Sunrenirirepa’ (U.S. Plant Pat. No. 14,302) and the similar variety ‘Sunrenilabu’ (U.S. Plant Pat. No. 10,843) for comparison. As a result, one plant was selected in view of flower size and color, and its growth habit, and it was concluded that the finally selected plant is distinguishable from any other variety whose existence is known to us and is uniform and stable in its characteristics. The new variety reproduces true to type in successive generations of asexual reproduction. The new variety has been named ‘Sunrenilapa’.
In the following description the color-coding is in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England.
