plant named ‘BKPBECVP’

Abstract

A new and distinct cultivar of Begonia plant named ‘BKPBECVP’, characterized by its broadly upright, somewhat outwardly spreading and mounded plant habit; moderately freely basal branching habit; medium-size leaves; uniform and freely flowering habit; and flowers that are light pink in color on both the upper and lower surfaces.

Description

Botanical designation: Begonia hiemalis.

Cultivar denomination: ‘BKPBECVP’.

BACKGROUND OF THE INVENTION

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

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Amstelveen, The Netherlands. The objective of the breeding program was to develop new freely branching and freely flowering Begonia plants with attractive foliage and flower colors.

The new Begonia plant originated from a cross-pollination made by the Inventor in September, 2006 of a proprietary selection of Begonia hiemalis identified as code number 06-187-01, not patented, as the female, or seed, parent with a proprietary selection of Begonia hiemalis identified as code number 6500604, 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 Amstelveen, The Netherlands in October, 2007.

Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Amstelveen, The Netherlands since February, 2008 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 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 ‘BKPBECVP’. These characteristics in combination distinguish ‘BKPBECVP’ as a new and distinct Begonia plant:

• • 1. Broadly upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Moderately freely basal branching habit.
  • 3. Medium-size leaves.
  • 4. Uniform and freely flowering habit.
  • 5. Flowers that are light pink in color on both the upper and lower surfaces.

Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection primarily in the following characteristics:

• • 1. Leaves of plants of the new Begonia are lighter green in color than leaves of plants of the female parent selection.
  • 2. Leaves of plants of the new Begonia are glabrous whereas leaves of plants of the female parent selection are slightly pubescent.
  • 3. Plants of the new Begonia have smaller flowers than plants of the female parent selection.

Plants of the new Begonia can be compared to plants of the male parent selection. 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 larger flowers than plants of the male parent selection.
  • 2. Plants of the new Begonia and the male parent selection differ slightly in flower color as plants of the male parent selection have pale pink-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia ‘Nelly’, not patented. In side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Begonia differed from plants of ‘Nelly’ in the following characteristics:

• • 1. Plants of the new Begonia were more upright than plants of ‘Nelly’.
  • 2. Plants of the new Begonia were not as compact as plants of ‘Nelly’.
  • 3. Plants of the new Begonia and ‘Nelly’ differed slightly in flower color.

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 ‘BKPBECVP’ grown in a container.

The photograph on the second sheet is a close up view of the upper and lower surfaces of typical flower buds, flowers and leaves of ‘BKPBECVP’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were grown in 12-cm containers during the winter in a glass-covered greenhouse in Maasdijk, The Netherlands.
