plant named ‘Sunpararopi’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunpararopi’, characterized by its vining plant habit; vigorous growth habit; relatively small glossy leaves; freely branching and flowering habit; medium-sized reddish pink-colored flowers; and long flowering period.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPARAROPI’.

BACKGROUND OF THE INVENTION

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

The new Mandevilla 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 create new vining and freely-branching Mandevilla plants with numerous small dark green-colored leaves and attractive flowers.

The new Mandevilla plant originated from a cross-pollination made by the Inventor in Higashiomi, Shiga, Japan in April, 2004, of a proprietary selection of Mandevilla hybrida identified as code number M35-4, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number M28-3, not patented, as the male, or pollen, parent. The new Mandevilla 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 November, 2005.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan, since December, 2005, has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla 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 ‘Sunpararopi’. These characteristics in combination distinguish ‘Sunpararopi’ as a new and distinct cultivar:

• • 1. Vining plant habit.
  • 2. Vigorous growth habit.
  • 3. Relatively small glossy leaves.
  • 4. Freely branching and flowering habit.
  • 5. Medium-sized reddish pink-colored flowers.
  • 6. Long flowering period.

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

• • 1. Plants of the new Mandevilla are more vigorous than plants of the female parent selection.
  • 2. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have pale pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunmandecripi’, disclosed in a U.S. Plant Pat. No. 18,578. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunmandecripi’ in the following characteristics:

• • 1. Plants of the new Mandevilla were more vigorous than plants of ‘Sunmandecripi’.
  • 2. Plants of the new Mandevilla were shorter than plants of
  • ‘Sunmandecripi’.
  • 3. Plants of the new Mandevilla had thicker stems than plants of ‘Sunmandecripi’.
  • 4. Plants of the new Mandevilla had smaller leaves than plants of ‘Sunmandecripi’.
  • 5. Plants of the new Mandevilla had smaller flowers than plants of ‘Sunmandecripi’.
  • 6. Plants of the new Mandevilla and ‘Sunmandecripi’ differed in flower color as plants of ‘. Sunmandecripi’ had red purple-colored flowers.
