Abstract

A new and distinct cultivar of Mandevilla plant named ‘QD-94’, characterized by its compact and upright plant habit; freely branching habit; dense and bushy appearance; dark green-colored leaves; freely flowering habit; and bright purplish pink-colored flowers with bright yellow-colored centers that are held beyond the foliar plane.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘QD-94’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATION

A European Community Plant Breeder's Rights application for the instant plant was filed by the Assignee of the instant application, Graff Breeding A/S of Sabro, Denmark on Apr. 16, 2025, application number 2359470. Foreign priority is not claimed to this European Plant Breeder's Rights application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla sanderi and hereinafter referred to by the name ‘QD-94’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Sabro, Denmark. The objective of the breeding program is to create new compact and freely branching Mandevilla plants with numerous attractive flowers.

The new Mandevilla plant originated from a cross-pollination in Sabro, Denmark in August 2019 of a proprietary selection of Mandevilla sanderi identified as code number M-2011-0008, not patented, as the female, or seed, parent with a proprietary selection of Mandevilla sanderi identified as code number M-2013-0902, 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 Sabro, Denmark in May 2020.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Sabro, Denmark, since September 2020 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 ‘QD-94’. These characteristics in combination distinguish ‘QD-94’ as a new and distinct Mandevilla plant:

- 1. Compact and upright plant habit.
- 2. Freely branching habit; dense and bushy appearance.
- 3. Dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Bright purplish pink-colored flowers with bright yellow-colored centers that are held beyond the foliar plane.

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 bright purplish pink-colored flowers whereas plants of the female parent selection have soft pink-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 new Mandevilla have bright purplish pink-colored flowers whereas plants of the male parent selection have soft pink-colored flowers. In addition, plants of the new Mandevilla are more upright and more compact than plants of the male parent selection.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘QD5’, disclosed in U.S. Plant Pat. No. 32,469. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants of ‘QD5’ in the following characteristics:

- 1. Plants of the new Mandevilla are more upright than and not as broad as plants of ‘QD5’.
- 2. Plants of the new Mandevilla have larger flowers than plants of ‘QD5’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘QD-94’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close up view of a typical open flower and developing flower bud of ‘QD-94’.

The photograph on the third sheet (FIG. 3 ) is a close up view of typical developing and fully developed leaves of ‘QD-94’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 13-cm containers in a glass-covered greenhouse in Sabro, Denmark and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 19° C. to 21° C. and light levels ranged from 40 klux to 50 klux. Plants were pinched two times and were 31 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
