Title: Torenia Plant Named ‘Sunrenikonho’

Applicants: Tetsuya Kako & Kiyoshi Miyazaki

Filed: Concurrently with this application (U.S. Plant patent application No. 12/590,019)

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Torenia plant, botanically known as Torenia sp. and hereinafter referred to by the name ‘Sunrenikonpe’.

The new Torenia plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new freely-branching Torenia plants with mounding habit and numerous large flowers.

The new Torenia plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in July, 2006 of a proprietary selection of Torenia sp, identified as code number TP-1, not patented, as the female, or seed, parent with a proprietary selection of Torenia sp. identified as code number TFOEx-W, not patented, as the male, or pollen, parent. The new Torenia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in March, 2007.

Asexual reproduction of the new Torenia plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April, 2007, has shown that the unique features of this new Torenia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Torenia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunrenikonpe’. These characteristics in combination distinguish ‘Sunrenikonpe’ as a new and distinct cultivar of Torenia:

- 1. Compact and mounding to trailing plant habit.
- 2. Freely branching habit.
- 3. Freely flowering habit.
- 4. Long flowering period.
- 5. Light violet-colored flowers.
- 6. Good garden performance.

Plants of the new Torenia differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Torenia are more mounding than plants of the female parent selection.
- 2. Plants of the new Torenia and the female parent selection differ in flower color as plants of the female parent selection have light purple-colored flowers.

Plants of the new Torenia differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Torenia are more mounding and trailing than plants of the male parent selection.
- 2. Plants of the new Torenia and the male parent selection differ in flower color as plants of the male parent selection have pink-colored flowers.

Plants of the new Torenia can be compared to plants of Torenia sp. ‘Sunrenikonho’, disclosed in U.S. Plant patent application No. 12/590,019, filed concurrently. Plants of the new Torenia and ‘Sunrenikonho’ differ primarily in flower color as plants of ‘Sunrenikonho’ have white-colored flowers.

Plants of the new Torenia can also be compared to plants of Torenia ‘Sunrenilabu’, disclosed in U.S. Plant Pat. No. 10,843. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Torenia and ‘Sunrenilabu’ differed in the following characteristics:

- 1. Plants of the new Torenia were larger and more mounding than plants of ‘Sunrenilabu’.
- 2. Plants of the new Torenia had thicker stems than plants of ‘Sunrenilabu’.
- 3. Plants of the new Torenia had larger leaves than plants of ‘Sunrenilabu’.
- 4. Plants of the new Torenia were more freely flowering than plants of ‘Sunrenilabu’.
- 5. Flowers of plants of the new Torenia had a yellow-colored blotch whereas flowers of plants of ‘Sunrenilabu’ did not have a yellow-colored blotch.
- 6. Plants of the new Torenia and ‘Sunrenilabu’ differed slightly in flower color.
