CROSS REFERENCED TO CLOSELY-RELATED APPLICATIONS

Title: Begonia Plant Named ‘KRSSUCO01’.

Applicant: Lubbertus H. Koppe.

Filed: Concurrently with this application U.S. Plant application Ser. No. 13/573,166.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially known as Elatior Begonia and hereinafter referred to by the name ‘KRSSUSA01’.

The new Begonia plant is a naturally-occurring whole plant mutation of a proprietary selection of Begonia×hiemalis identified as code number KV03-0205-02, not patented. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Ermelo, The Netherlands in August, 2010.

Asexual reproduction of the new Begonia plant by vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since November, 2010 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 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 ‘KRSSUSA01’. These characteristics in combination distinguish ‘KRSSUSA01’ as a new and distinct Begonia plant:

    • 1. Compact, upright, outwardly spreading and mounded plant habit.
    • 2. Freely branching habit.
    • 3. Dark green-colored leaves.
    • 4. Numerous large salmon red-colored flowers with lighter-colored centers that are held above and beyond the foliar plane.
    • 5. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the parent selection in flower color. Plants of the new Begonia have salmon red-colored flowers whereas plants of the parent selection have dark pink-colored flowers. In addition, plants of the new Begonia have shorter internodes than plants of the parent selection.

Plants of the new Begonia can be compared to plants of the Begonia ‘KRSSUCO01’, U.S. Plant Patent application Ser. No. 13/573,166, filed concurrently. Plants of the new Begonia differ primarily from plants of ‘KRSSUCO01’ in flower color as plants of the new Begonia have salmon red-colored flowers whereas plants of ‘KRSSUCO01’ have coral red-colored flowers. In addition, plants of the new Begonia have longer leaf petioles than plants of ‘KRSSUCO01’.

Plants of the new Begonia can be compared to plants of Begonia×hiemalis ‘KRSSUWH01’, disclosed in U.S. Plant Pat. No. 23,205. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed primarily from plants of ‘KRSSUWH01’ in flower color as plants of ‘KRSSUWH01’ had white-colored flowers.

Plants of the new Begonia can also be compared to plants of Begonia×hiemalis ‘Dark Britt’, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed primarily from plants of ‘Dark Britt’ in flower color as plants of ‘Dark Britt’ had orange-colored flowers. In addition, flowers of plants of the new Begonia had fewer tepaloids than flowers of plants of ‘Dark Britt’.

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 flowering plant of ‘KRSSUSA01’ grown in a container.

The photograph on the second sheet are close up views of the upper and lower surfaces of typical leaves (right) and upper, lateral and lower surfaces of developing and open flowers of ‘KRSSUSA01’ (left).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring 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 averaged 20° C. and night temperatures averaged 18° C. Plants were pinched one time and were ten weeks old when the photographs and description were taken.
