STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR/APPLICANT & ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Koppe Royalty B.V. of Putten, The Netherlands on Nov. 23, 2021, application number 2021/3016. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 an Elatior Begonia and hereinafter referred to by the name ‘KRHAISU01’.

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 freely-branching Begonia plants with excellent postproduction longevity and attractive flower color.

The new Begonia plant originated from a cross-pollination made by the Inventor in March, 2014 of a proprietary selection of Begonia x tuberhybrida identified as code number KV14-3481-004, not patented, as the female, or seed, parent with a proprietary selection of Begonia socotrana identified as code number S00, 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 May, 2015.

Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since August, 2015 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 ‘KRHAISU01’. These characteristics in combination distinguish ‘KRHAISU01’ as a new and distinct Begonia plant:

    • 1. Broadly upright to spreading and mounded plant habit.
    • 2. Moderately vigorous growth habit and moderate growth rate.
    • 3. Moderately freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Freely flowering habit.
    • 6. Double-type male flowers that are pinkish apricot in color and held above and beyond the foliar plane.
    • 7. Good postproduction longevity.

Plants of the new Begonia differ primarily from plants of the female parent selection in flower color as plants of the new Begonia have pinkish apricot-colored flowers whereas plants of the female parent selection have salmon orange-colored flowers.

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 double flowers whereas plants of the male parent selection have single flowers.
    • 2. Plants of the new Begonia have pinkish apricot-colored flowers whereas plants of the male parent selection have purplish pink-colored flowers.

Plants of the new Begonia can be compared to plants of Begonia x 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 flowers of plants of the new Begonia are pinkish apricot in color whereas flowers of plants of ‘Dark Netja’ are bright pink in color.

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) comprises a side perspective view of a typical plant of ‘KRHAISU01’ grown in a container.

The photograph on the second sheet (FIG. 2) are close up views of the upper (right) and lower (left) surfaces of typical leaves and flowers of ‘KRHAISU01’, and in the center of the photograph is a close-up view of typical flower buds.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn in 13-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.
