Mandevilla plant named ‘Sunparacoho’

Abstract

A new and distinct cultivar of mandevilla plant named ‘Sunparacoho’, characterized by its vining plant habit; vigorous growth habit; freely branching habit; freely flowering habit; medium-sized white-colored flowers; and long flowering period.

Description

Botanical designation: Mandevilla×amabilis.

Cultivar denomination: ‘SUNPARACOHO’.

BACKGROUND OF THE INVENTION

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

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 white-colored 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×amabilis identified as code number M-7, not patented, as the female, or seed parent with a proprietary selection of Mandevilla×amabilis identified as code number M-1, 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 October, 2005.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan, since November, 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 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 ‘Sunparacoho’. These characteristics in combination distinguish ‘Sunparacoho’ as a new and distinct Mandevilla plant:

• • 1. Vining plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Medium-sized white-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 have smaller leaves than plants of the female parent selection.
  • 2. Plants of the new Mandevilla have smaller flowers than plants of the female parent selection.
  • 3. Petal apices of plants of the new Mandevilla are rounded whereas petal apices of plants of the female parent selection are acute.

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 the following characteristics:

• • 1. Plants of the new Mandevilla have larger leaves than plants of the male parent selection.
  • 2. Plants of the new Mandevilla have larger flowers than plants of the male parent selection.
  • 3. Petal apices of plants of the new Mandevilla are rounded whereas petal apices of plants of the male parent selection are truncate.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunmandeho’, disclosed in a U.S. Plant Pat. No. 11,556. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunmandeho’ in the following characteristics:

• • 1. Plants of the new Mandevilla had shorter lateral branches than plants of ‘Sunmandeho’.
  • 2. Plants of the new Mandevilla had shorter internodes than plants of ‘Sunmandeho’.
  • 3. Plants of the new Mandevilla had smaller leaves than plants of ‘Sunmandeho’.
  • 4. Plants of the new Mandevilla were more freely flowering than plants of ‘Sunmandeho’.
  • 5. Plants of the new Mandevilla had smaller flowers than plants of ‘Sunmandeho’.
  • 6. Petal apices of plants of the new Mandevilla were rounded whereas petal apices of plants of ‘Sunmandeho’ were cuspidate.
