Abstract

A new and distinct cultivar of Mandevilla plant named ‘Inmanbegsc’, characterized by its broadly upright and vining plant habit; moderately vigorous growth habit; freely branching habit; glossy dark green-colored leaves; early and freely flowering habit; large deep scarlet red-colored flowers with slightly undulate margins and orange red-colored centers that resist fading; and relative tolerance to low temperatures.

Description

Botanical designation: Mandevilla sanderi.
Cultivar denomination: ‘INMANBEGSC’.
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 ‘Inmanbegsc’.
The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa and Gensingen, Germany. The objective of the breeding program is to create new freely branching Mandevilla plants that flower early and freely and have attractive flowers that resist fading and sun scald.
The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in January, 2014 of a proprietary selection of Mandevilla sanderi identified as code number D11-2524-1, not patented, as the female, or seed parent with a proprietary selection of Mandevilla sanderi identified as code number D11-2102-1, 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 Gensingen, Germany in June, 2015.
Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in Gensingen, Germany since August, 2015 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 ‘Inmanbegsc’. These characteristics in combination distinguish ‘Inmanbegsc’ as a new and distinct Mandevilla plant:
    • 1. Broadly upright and vining plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Glossy dark green-colored leaves.
    • 5. Early and freely flowering habit.
    • 6. Large deep scarlet red-colored flowers with slightly undulate margins and orange red-colored centers that resist fading.
    • 7. Relatively tolerant to low temperatures.
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 are more freely branching and bushier than plants of the female parent selection.
    • 2. Plants of the new Mandevilla flower later than plants of the female parent selection.
    • 3. Plants of the new Mandevilla have deep scarlet red-colored flowers with orange red-colored centers whereas plants of the female parent selection have slightly deep red-colored flowers with white-colored centers.
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 stronger roots than plants of the male parent selection.
    • 2. Plants of the new Mandevilla are more upright than plants of the male parent selection.
    • 3. Leaves of plants of the new Mandevilla are smoother and flatter than leaves of plants of the male parent selection.
    • 4. Flower margins of plants of the new Mandevilla are undulate whereas flower margins of plants of the male parent selection are not undulate.
Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Inmanredeep’, disclosed in U.S. Plant Pat. No. 29,096. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Inmanredeep’ in the following characteristics:
    • 1. Plants of the new Mandevilla are larger than plants of ‘Inmanredeep’.
    • 2. Plants of the new Mandevilla have larger flowers than plants of ‘Inmanredeep’.
    • 3. Flowers of plants of the new Mandevilla are brighter red in color than flowers of plants of ‘Inmanredeep’.
    • 4. Flower margins of plants of the new Mandevilla are undulate whereas flower margins of plants of ‘Inmanredeep’ are not undulate.
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 ‘Inmanbegsc’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flower of ‘Inmanbegsc’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 11-cm containers in a glass-covered greenhouse in Heidesheim, Germany and under cultural practices typical of commercial Mandevilla production.
