USPP23959P2 - Mandevilla plant named ‘Sunparacore’ - Google Patents

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunparacore’, characterized by its compact plant habit; vigorous growth habit; freely branching habit and short internodes, dense and bushy plant form; freely flowering habit; medium-sized dark red-colored flowers; and long flowering period.

Description

Botanical designation: Mandevilla×amabilis.

Cultivar denomination: ‘SUNPARACORE’.

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 ‘Sunparacore’.

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 freely-branching Mandevilla plants with numerous dark red-colored flowers.

The new Mandevilla plant originated from an open-pollination in Higashiomi, Shiga, Japan in April, 2006 of a proprietary selection of Mandevilla×amabilis identified as code number M37-mt1, not patented, as the female, or seed parent with an unknown selection of Mandevilla×amabilis 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 open-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2007.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan, since November, 2007 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 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 ‘Sunparacore’. These characteristics in combination distinguish ‘Sunparacore’ as a new and distinct Mandevilla plant:

• • 1. Compact plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit and short internodes, dense and bushy plant form.
  • 4. Freely flowering habit.
  • 5. Medium-sized dark red-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 slightly longer internodes than plants of the female parent selection.

2. Petals of plants of the new Mandevilla are ovate in shape whereas petals of plants of the female parent selection are spatulate in shape.

• • 3. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have red purple-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunmanderemi’, disclosed in a U.S. Plant Pat. No. 16,449. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunmanderemi’ in the following characteristics:

• • 1. Plants of the new Mandevilla had longer internodes than plants of ‘Sunmanderemi’.
  • 2. Petals of plants of the new Mandevilla were ovate in shape whereas petals of plants of ‘Sunmanderemi’ were spatulate in shape.
  • 3. Plants of the new Mandevilla had smaller leaves than plants of ‘Sunmanderemi’.
  • 4. Flowers of plants of the new Mandevilla were darker in color than flowers of plants of ‘Sunmanderemi’.
