Abstract

A new and distinct cultivar of Begonia plant named ‘KROUTWH01’, characterized by its broadly upright and mounded plant habit; moderately vigorous growth habit; moderately freely branching habit; dark green-colored leaves; large single-type white-colored flowers variably blushed with red purple that are positioned above and beyond the foliar plane; and continuous flowering throughout the summer.

Description

Botanical designation: Begonia boliviensis X Begonia x tuberhybrida.

Cultivar denomination: ‘KROUTWH01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis X Begonia x tuberhybrida and hereinafter referred to by the name ‘KROUTWH01’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Ermelo, The Netherlands. The objective of the breeding program is to create new Begonia plants with uniform plant habit and numerous attractive flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in Ermelo, The Netherlands in September, 2015 of Begonia boliviensis ‘Yagance’, disclosed in U.S. Plant Pat. No. 19,817, as the female, or seed, parent with a proprietary selection of Begonia x tuberhybrida identified as code number KV11K1912-012, 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 Ermelo, The Netherlands in June, 2016.

Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since March, 2017 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 ‘KROUTWH01’. These characteristics in combination distinguish ‘KROUTWH01’ as anew and distinct Begonia plant:

    • 1. Broadly upright and mounded plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Moderately freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Large single-type white-colored flowers variably blushed with red purple that are positioned above and beyond the foliar plane.
    • 6. Continuous flowering throughout the summer.

Plants of the new Begonia differ primarily from plants of the female parent, ‘Yagance’, in the following characteristics:

    • 1. Plants of the new Begonia are more freely flowering than plants of ‘Yagance’.
    • 2. Plants of the new Begonia have larger and more open flowers than plants of ‘Yagance’.

Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Begonia are more freely flowering than plants of the male parent selection.
    • 2. Flowers of plants of the new Begonia are larger and more open than flowers of plants of the male parent selection.

Plants of the new Begonia can be compared to plants of Begonia boliviensis X Begonia x tuberhybrida ‘KROUTOR01’, disclosed in U.S. Plant Pat. No. 26,248. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed primarily from plants of ‘KROUTOR01’ in flower color as plants of the new Begonia have white-colored flowers blushed with red purple whereas plants of ‘KROUTOR01’ have dark orange-colored 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 plant of ‘KROUTWH01’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) is a close up view of typical flowers and leaves of ‘KROUTWH01’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring and early summer in 10.5-cm containers in a glass-covered greenhouse in Ermelo, The Netherlands and under cultural practices typical of commercial Begonia production. During the production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 16° C. to 18° C. Plants were three months 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.
