Abstract

A new and distinct cultivar of Begonia plant named ‘KROUTRE01’, characterized by its broadly upright and mounded plant habit; moderately vigorous growth habit; moderately freely branching habit; dark greyed green-colored leaves; large single-type red-colored flowers 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: ‘KROUTRE01’.
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 ‘KROUTRE01’.
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, 2014 of a proprietary selection of Begonia boliviensis identified as code number KV13H1260-004, not patented, as the female, or seed, parent with Begonia x tuberhybrida ‘Nonstop Mocca’, 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 October, 2015.
Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Ermelo, 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 ‘KROUTRE01’. These characteristics in combination distinguish ‘KROUTRE01’ as a new and distinct Begonia plant:
    • 1. Broadly upright and mounded plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Moderately freely branching habit.
    • 4. Dark greyed green-colored leaves.
    • 5. Large single-type red-colored flowers 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 selection in the following characteristics:
    • 1. Plants of the new Begonia are larger and more mounding than plants of the female parent selection.
    • 2. Plants of the new Begonia have larger flowers than plants of the female parent selection.
Plants of the new Begonia differ primarily from plants of the male parent, ‘Nonstop Mocca’, in the following characteristics:
    • 1. Plants of the new Begonia have dark greyed green-colored leaves whereas plants of ‘Nonstop Mocca’ have bronze-colored leaves.
    • 2. Plants of the new Begonia have single-type flowers whereas plants of ‘Nonstop Mocca’ have double-type flowers.
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 red-colored flowers 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 ‘KROUTRE01’ 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 ‘KROUTRE01’.
 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.
