Abstract

A new and distinct cultivar of Mandevilla plant named ‘QD5’, characterized by its compact, broadly upright to vining plant habit; moderately vigorous to vigorous growth habit; freely branching habit; dense and bushy appearance; dark green-colored leaves; freely flowering habit; and relatively large red purple-colored flowers with orange yellow-colored throats.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘QD5’.

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 ‘QD5’.

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 conducted by the Inventor in Sabro, Denmark in August, 2015 of a proprietary selection of Mandevilla sanderi identified as code number GB 2013-0902, not patented, as the female, or seed, parent with a proprietary selection of Mandevilla sanderi identified as code number GB 2013-0818, 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, 2016.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Sabro, Denmark, since September, 2016 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 ‘QD5’. These characteristics in combination distinguish ‘QD5’ as a new and distinct Mandevilla plant:

- 1. Compact, broadly upright to vining plant habit.
- 2. Moderately vigorous to vigorous growth habit.
- 3. Freely branching habit; dense and bushy appearance.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit.
- 6. Relatively large red purple-colored flowers with orange yellow-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 red purple-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 growth habit as plants of the new Mandevilla are more compact and denser than and not as vigorous and open as plants of the male parent selection.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Sundaville Beauty Rose’, not patented. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Sundaville Beauty Rose’ in the following characteristics:

- 1. Plants of the new Mandevilla are more compact than and not as vigorous as plants of ‘Sundaville Beauty Rose’.
- 2. Plants of the new Mandevilla do not produce tendrils whereas plants of ‘Sundaville Beauty Rose’ produce tendrils.

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 of 2) comprises a side perspective view of a typical flowering plant of ‘QD5’ grown in a container.

The photographs on the second sheet (FIG. 2 of 2) are close-up views of typical developing flowers and developing leaves of ‘QD5’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn 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 29 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.
