Abstract

A new and distinct cultivar of Begonia plant named ‘BKPBEMCRG’, characterized by its broadly upright and mounded plant habit; sturdy plants with freely basal branching habit; dark green-colored leaves; uniform and freely flowering habit; and single flowers that are red in color.

Description

Botanical designation: Begonia x hiemalis.
Cultivar denomination: ‘BKPBEMCRG’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia x hiemalis, commercially referred to as Elatior Begonia and hereinafter referred to by the name ‘BKPBEMCRG’.
The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program was to develop new freely branching and freely flowering Begonia plants with attractive flowers and good garden performance.
The new Begonia plant originated from a cross-pollination made by the Inventor in May, 2015 of a proprietary selection of Begonia x tuberhybrida identified as code number 09-0008-03, not patented, as the female, or seed, parent with an unnamed proprietary selection of Begonia socotrana, not patented, as the male, or pollen, parent. The new Begonia 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 Maasdijk, The Netherlands in October, 2015.
Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since March, 2016 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Begonia 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 ‘BKPBEMCRG’. These characteristics in combination distinguish ‘BKPBEMCRG’ as a new and distinct Begonia plant:
    • 1. Broadly upright and mounded plant habit.
    • 2. Sturdy plants with freely basal branching habit.
    • 3. Dark green-colored leaves.
    • 4. Uniform and freely flowering habit.
    • 5. Single flowers that are red in color.
Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Leaves of plants of the new Begonia are dark green in color whereas leaves of plants of the female parent selection are reddish green in color.
    • 2. Leaves of plants of the new Begonia are glabrous whereas leaves of plants of the female parent selection are pubescent.
Plants of the new Begonia can be compared to plants of the male parent selection. Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Begonia have red-colored flowers whereas plants of the male parent selection have pink-colored flowers.
    • 2. Flowers of plants of the new Begonia do not produce pollen whereas flowers of plants of the male parent selection produce pollen.
Plants of the new Begonia can be compared to plants of Begonia x hiemalis ‘BKPBECRM’, disclosed in U.S. Plant Pat. No. 28,818. Plants of the new Begonia differ primarily from plants of ‘BKPBECRM’ in the following characteristics:
    • 1. Leaves of plants of the new Begonia are larger and darker green in color than leaves of plants of ‘BKPBECRM’.
    • 2. Plants of the new Begonia have single-type flowers whereas plants of ‘BKPBECRM’ have double-type flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Begonia 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 colors of the new Begonia plant.
The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical flowering plant of ‘BKPBEMCRG’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) are close-up views of a typical flower bud and the upper and lower surfaces of typical developed flowers and leaves of ‘BKPBEMCRG’.
DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following observations and measurements were grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Dinslaken, Germany. During the production of the plants, day and night temperatures ranged from 19° to 21° C. Plants were eleven weeks from planting rooted cuttings when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
