USPP18967P2 - Begonia plant named ‘Elektra Pink’ - Google Patents

Abstract

A new and distinct cultivar of Begonia plant named ‘Elektra Pink’, characterized by its upright and mounded plant habit; freely branching habit; double flowers that are dark pink in color and held above the foliage; and excellent postproduction longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘Elektra Pink’.

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 ‘Elektra Pink’.

The new Begonia 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 vigorous Begonia cultivars with excellent postproduction longevity.

The new Begonia originated from a cross-pollination made by the Inventor in Ermelo, The Netherlands in January, 1999 of an unnamed selection of Begonia tuberhybrida, not patented, as the female, or seed, parent with an unnamed selection of Begonia socotrana, not patented. The cultivar Elektra Pink was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Ermelo, The Netherlands in June, 1999.

Asexual reproduction of the new Begonia by cuttings harvested in a controlled environment in Ermelo, The Netherlands since June, 2000, has shown that the unique features of this new Begonia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Elektra Pink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Elektra Pink’. These characteristics in combination distinguish ‘Elektra Pink’ as a new and distinct Begonia:

• • 1. Upright and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Double flowers that are dark pink in color and held above the foliage.
  • 4. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the female parent selection primarily in flower color as plants of the female parent selection have yellow-colored flowers.

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

• • 1. Plants of the new Begonia are more freely branching than plants of the male parent selection.
  • 2. Plants of the new Begonia have darker green-colored leaves than plants of the male parent selection.
  • 3. Plants of the new Begonia have darker pink-colored leaves than plants of the male parent selection.

Plants of the new Begonia can also be compared to plants of the cultivar Dark Netja, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed from plants of the cultivar Dark Netja in the following characteristics:

• • 1. Plants of the new Begonia had narrower leaves than plants of the cultivar Dark Netja.
  • 2. Flowers of plants of the new Begonia were more double than flowers of plants of the cultivar Dark Netja.
  • 3. Plants of the new Begonia and the cultivar Dark Netja differed in flower color as plants of the cultivar Dark Netja had pink and white-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.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Elektra Pink’ grown in a container.

The photograph at the bottom of the sheet is a close up view of typical leaves and flowers of ‘Elektra Pink’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Ermelo, The Netherlands, under commercial practice in a glass-covered greenhouse during the spring and summer. Average day and night temperature was about 20° C. during the first three to four weeks then lowered to an average day and night temperature of 19° C. until flowering. Four weeks after planting rooted cuttings in 12-cm containers, one week of long nyctoperiods of 16 hours was given followed by short nyctoperiods of eight hours until flowering. Plants used for the photographs and the description were about 15 weeks from planting.
