plant named ‘Sunpa 127’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Sunpa 127’, characterized by its trailing plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; and medium-sized white-colored flowers with yellow orange-colored throats.

Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPA 127’.

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 ‘Sunpa 127’.

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 trailing and freely branching Mandevilla plants with freely flowering habit and attractive flowers.

The new Mandevilla plant originated from a cross-pollination in Higashiomi, Shiga, Japan in May, 2010 of a proprietary selection of Mandevilla hybrida identified as code number 02MH11-4, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number MH-58, 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 September, 2011.

Asexual reproduction of the new Mandevilla plant by terminal vegetative cuttings in Higashiomi, Shiga, Japan since March, 2012 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 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 ‘Sunpa 127’. These characteristics in combination distinguish ‘Sunpa 127’ as a new and distinct Mandevilla plant:

• • 1. Trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Long flowering period.
  • 6. Medium-sized white-colored flowers with yellow orange-colored throats.

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 flower color as plants of the new Mandevilla have white-colored flowers whereas 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 plant habit as plants of the new Mandevilla have a trailing plant habit whereas plants of the male parent selection have a semi-upright plant habit.

Plants of the new Mandevilla can be compared to plants of the Mandevilla amabilis X Mandevilla boliviensis ‘Sunmandeho’, disclosed in U.S. Plant Pat. No. 11,556. In side-by-side comparisons, plants of the new Mandevilla differ from plants of ‘Sunmandeho’ in the following characteristics:

• • 1. Plants of the new Mandevilla are more trailing than and not as upright as plants of ‘Sunmandeho’.
  • 2. Plants of the new Mandevilla have shorter internodes than plants of ‘Sunmandeho’.
  • 3. Plants of the new Mandevilla have smaller and darker green-colored leaves than plants of ‘Sunmandeho’.
  • 4. Plants of the new Mandevilla have smaller flowers than plants of ‘Sunmandeho’.

DETAILED BOTANICAL DESCRIPTION

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