plant named ‘Innbolpink’

Abstract

A new and distinct cultivar of Begonia plant named ‘Innbolpink’, characterized by its compact and mounded to trailing plant habit; freely branching habit; dense and bushy growth habit; medium green-colored leaves; and numerous single flowers that are bright pink in color.

Description

Botanical designation: Begonia×tuberhybrida.

Cultivar denomination: ‘Innbolpink’.

BACKGROUND OF THE INVENTION

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

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop new compact Begonia cultivars with attractive single flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in January, 2005 of a proprietary selection of Begonia×tuberhybrida identified as code number B 04 19-1, not patented, as the female, or seed, parent with Begonia×tuberhybrida ‘Weiβ 1’, not patented, as the male, or pollen, parent. The new Begonia was discovered and selected by the Inventor as a single plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Gensingen, Germany in September, 2005.

Asexual reproduction of the new Begonia plant by vegetative cuttings in a controlled greenhouse environment in Gensingen, Germany since October, 2005, 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. The phenotype may vary somewhat with variations in environment 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 ‘Innbolpink’. These characteristics in combination distinguish ‘Innbolpink’ as a new and distinct cultivar of Begonia:

• • 1. Compact and mounded to trailing plant habit.
  • 2. Freely branching habit; dense and bushy growth habit.
  • 3. Medium green-colored leaves.
  • 4. Numerous single flowers that are bright pink in color.

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

• • 1. Plants of the new Begonia are more compact than and not as vigorous as plants of the female parent selection.
  • 2. Plants of the new Begonia are more freely branching than plants of the female parent selection.

Plants of the new Begonia differ from plants of the male parent, ‘Weiβ 1’ in the following characteristics:

• • 1. Plants of the new Begonia are more freely branching than plants of ‘Weiβ 1’.
  • 2. Plants of the new Begonia have single flowers whereas plants of ‘Weiβ 1’ have double flowers.
  • 3. Plants of the new Begonia and ‘Weiβ 1’ differ in flower color as plants of ‘Weiβ 1’ have white-colored flowers.

Plants of the new Begonia can also be compared to plants of the Begonia×tuberhybrida ‘Bonfire’, disclosed in U.S. Plant Pat. No. 15,108. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Begonia differed from plants of ‘Bonfire’ in the following characteristics:

• • 1. Plants of the new Begonia were more compact and mounded than plants of ‘Bonfire’.
  • 2. Plants of the new Begonia were more freely branching and denser than plants of ‘Bonfire’.
  • 3. Plants of the new Begonia and ‘Bonfire’ differed in flower color as plants of ‘Bonfire’ had orange-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia, 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 at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Innbolpink’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘Innbolpink’.

DETAILED BOTANICAL DESCRIPTIONS

Plants used for the aforementioned photographs and following observations and measurements were grown in Bonsall, Calif. in one-gallon containers and under commercial practice in a shaded polyethylene-covered greenhouse during the late summer. During the production of the plants, day temperatures ranged from 18° C. to 35° C., night temperatures ranged from 10° C. to 24° C. Plants used for the photographs and the description were pinched one time and were twelve weeks from planting.
