Description

Botanical designation: Catharanthus roseus.

Cultivar denomination: ‘SUNCATH 132’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee, Suntory Flowers Limited of Tokyo, Japan, assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Catharanthus plant, botanically known as Catharanthus roseus and hereinafter referred to by the cultivar name ‘Suncath 132’.

The new Catharanthus plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new uniform and freely branching Catharanthus plants with numerous small attractive flowers.

The new Catharanthus plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in September, 2011 of a proprietary selection of Catharanthus roseus identified as code designation FS22-9, not patented, as the female, or seed, parent with a proprietary selection of Catharanthus roseus identified as code designation CL, not patented, as the male, or pollen, parent. The new Catharanthus 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 September, 2013.

Asexual reproduction of the new Catharanthus plant by vegetative tip cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since December, 2013, has shown that the unique features of this new Catharanthus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Catharanthus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Suncath 132’. These characteristics in combination distinguish ‘Suncath 132’ as a new and distinct Catharanthus plant:

• • 1. Upright to outwardly spreading and uniformly mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely basal branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Relatively small star-shaped purplish red-colored flowers with white-colored centers.
  • 7. Good garden performance.

Plants of the new Catharanthus can be compared to plants of the female parent selection. Plants of the new Catharanthus differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Catharanthus have smaller flowers than plants of the female parent selection.
  • 2. Plants of the new Catharanthus have purplish red-colored flowers whereas plants of the female parent selection have red-colored flowers.

Plants of the new Catharanthus can be compared to plants of the male parent selection. Plants of the new Catharanthus differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Catharanthus have smaller flowers than plants of the male parent selection.
  • 2. Plants of the new Catharanthus have purplish red-colored flowers whereas plants of the male parent selection have lavender pink-colored flowers.

Plants of the new Catharanthus can be compared to plants of the Catharanthus roseus ‘Suncatha 2460’, disclosed in U.S. Plant Pat. No. 27,455. In side-by-side comparisons, plants of the new Catharanthus differ from plants of ‘Suncatha 2460’ in the following characteristics:

• • 1. Plants of the new Catharanthus are not as broad as plants of ‘Suncatha 2460’.
  • 2. Plants of the new Catharanthus have larger flower petals than plants of ‘Suncatha 2460’.
  • 3. Plants of the new Catharanthus and ‘Suncatha 2460’ differ in flower color as plants of the new Catharanthus have purplish red-colored flowers whereas plants of ‘Suncatha 2460’ have light red purple-colored flowers.
  • 4. Flowers of plants of the new Catharanthus have a larger “eye zone” than flowers of plants of ‘Suncatha 2460’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 24-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial production. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 15° C. Plants were four months old when the photographs were taken and five months old when the description was taken.
