Abstract

A new and distinct cultivar of Begonia plant named ‘KRELECE01’ characterized by its upright to somewhat outwardly spreading and mounded plant habit; moderately freely branching habit; moderately to freely flowering habit; double flowers that are cerise in color and held above the foliar plane; and excellent postproduction longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘KRELECE01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially referred to as an Elatior Begonia and hereinafter referred to by the name ‘KRELECE01’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in De Kwakel and Ermelo, The Netherlands. The objective of the breeding program is to create new vigorous Begonia plants with excellent postproduction longevity.

The new Begonia plant is a naturally-occurring whole plant mutation of Begonia×hiemalis ‘Elektra Pink’, disclosed in U.S. Plant Pat. No. 18,967. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Elektra Pink’ grown in a controlled greenhouse environment in De Kwakel, The Netherlands in March, 2013.

Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since January, 2014 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, daylength 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 ‘KRELECE01’. These characteristics in combination distinguish ‘KRELECE01’ as a new and distinct Begonia plant:

- 1. Upright to somewhat outwardly spreading and mounded plant habit.
- 2. Moderately freely branching habit.
- 3. Moderately to freely flowering habit.
- 4. Double flowers that are cerise in color and held above the foliar plane.
- 5. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the mutation parent, ‘Elektra Pink’, in flower color as plants of ‘Elektra Pink’ have pink-colored flowers.

Plants of the new Begonia can be compared to plants of Begonia×hiemalis ‘Dark Netja’, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differ primarily from plants of ‘Dark Netja’ in flower color as plants of ‘Dark Netja’ have light pink-colored flowers. In addition, plants of the new Begonia have double flowers whereas plants of ‘Dark Netja’ have semi-double 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 comprises a side perspective view of a typical plant of ‘KRELECE01’ grown in a container.

The photograph on the second sheet are close up views of the upper (right) and lower (left) surfaces of typical leaves and flowers of ‘KRELECE01’ and in the center of the photograph is a close-up view of typical flower buds with pedicel.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn in 12-cm containers in a shaded glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial Begonia production. During the production of the plants, day and night temperatures averaged 20° C. Plants were ten weeks old when the photographs and 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.
