Botanical designation: Begonia×hiemalis.
Cultivar denomination: ‘BKPBECHL’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially referred to as Elatior Begonia and hereinafter referred to by the name ‘Bkpbechl’.
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.
The new Begonia plant originated from a cross-pollination made by the Inventor in January, 2013 of a proprietary selection of Begonia×hiemalis identified as code number 6502406, not patented, as the female, or seed, parent with a proprietary selection of Begonia×hiemalis identified as code number 6500604, 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 August, 2013.
Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since November, 2013 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONPlants 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 ‘Bkpbechl’. These characteristics in combination distinguish ‘Bkpbechl’ as a new and distinct Begonia plant:
-
- 1. Broadly upright to outwardly spreading 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-type female flowers and fully double male flowers that are light 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. Plants of the new Begonia and the female parent selection differ in leaf texture as plants of the female parent selection have pubescent leaves.
- 2. Plants of the new Begonia and the female parent selection differ in flower color as plants of the female parent selection have very light pink-colored flowers.
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 and the male parent selection differ in flower form as plants of the male parent selection have single-type flowers.
- 2. Plants of the new Begonia and the male parent selection differ in flower color as plants of the male parent selection have pink-colored flowers.
Plants of the new Begonia can be compared to plants of the Begonia×hiemalis ‘Bkpbeegl’, disclosed in U.S. Plant Pat. No. 23,825. Plants of the new Begonia differ from plants of ‘Bkpbeegl’ in the following characteristics:
-
- 1. Plants of the new Begonia have darker green-colored leaves than plants of ‘Bkpbeegl’.
- 2. Plants of the new Begonia have larger flowers than plants of ‘Bkpbeegl’.
- 3. Plants of the new Begonia and ‘Bkpbeegl’ differ in flower color as plants of ‘Bkpbeegl’ have pink-colored flowers.
Plants of the new Begonia can be compared to plants of the Begonia×hiemalis ‘Bkpbeeep’, disclosed in U.S. Plant Pat. No. 27,116. Plants of the new Begonia differ from plants of ‘Bkpbeeep’ in the following characteristics:
-
- 1. Plants of the new Begonia are more open than plants of ‘Bkpbeeep’.
- 2. Plants of the new Begonia have more double flowers than plants of ‘Bkpbeeep’.
- 3. Plants of the new Begonia and ‘Bkpbeeep’ differ in flower color as plants of ‘Bkpbeeep’ have dark pink-colored flowers.
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 comprises a side perspective view of a typical flowering plant of ‘Bkpbechl’ grown in a container.
The photograph on the second sheet are close-up views of upper and lower surfaces of typical fully developed male flowers, typical flower buds and upper and lower surfaces of typical leaves of ‘Bkpbechl’.
Plants used for the aforementioned photographs and following observations and measurements were grown during the winter in 12-cm containers in a glass-covered greenhouse in Maasdijk, The Netherlands. During the production of the plants, day and night temperatures ranged from 19° to 21° C. Plants were ten weeks old 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.
