Abstract

A distinct cultivar of Dahlia plant named ‘Karma Bon Bini’, characterized by its straight and strong flowering stems; freely basal branching growth habit; cactus-type inflorescence form; yellow and red bi-colored ray florets; excellent garden performance; and excellent inflorescence longevity.

Description

Botanical classification/cultivar designation: Dahlia hybrida cultivar Karma Bon Bini.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida and hereinafter referred to by the name ‘Karma Bon Bini’.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Lisse, The Netherlands. The objective of the breeding program is to create new cut flower Dahlia cultivars with straight strong flowering stems, decorative inflorescence form, attractive ray floret colors, and good inflorescence longevity.
The new Dahlia originated from a cross-pollination made by the Inventor in 1996 of the Dahlia hybrida cultivar Bridgeview Aloha, not patented, as the female or seed parent with an unidentified selection of Dahlia hybrida, not patented, as the male or pollen parent. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Lisse, The Netherlands, in the summer of 1997. The selection of this plant was based on its strong straight stems and attractive ray floret coloration.
Asexual reproduction of the new Dahlia by cuttings was first conducted in a controlled environment in Lisse, The Netherlands in the Spring of 1998. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Karma Bon Bini 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 ‘Karma Bon Bini’. These characteristics in combination distinguish ‘Karma Bon Bini’ as a new and distinct Dahlia cultivar:
1. Straight and strong flowering stems.
2. Freely basal branching growth habit.
3. Cactus-type inflorescence form.
4. Yellow and red bi-colored ray florets.
5. Excellent garden performance.
6. Excellent inflorescence longevity.
Plants of the new Dahlia are most similar to plants of the female parent, the cultivar Bridgeview Aloha. However, in side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Bridgeview Aloha in the following characteristics:
1. Plants of the new Dahlia were shorter than plants of the cultivar Bridgeview Aloha.
2. Plants of the new Dahlia had stronger flowering stems than plants of the cultivar Bridgeview Aloha.
3. Plants of the new Dahlia had cactus-type inflorescences whereas plants of the cultivar Bridgeview Aloha had decorative-type inflorescences.
4. Ray floret coloration of plants of the new Dahlia was stronger and resisted fading better than plants of the cultivar Bridgeview Aloha.
Plants of the new Dahlia differ primarily from plants of the male parent, an unidentified selection, in ray floret coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Dahlia showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia.
The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Karma Bon Bini’.
The photograph on the second sheet is a close-up view of typical inflorescences of ‘Karma Bon Bini’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and the following observations and measurements describe plants grown and flowered during the summer and early autumn in Lisse, The Netherlands, in an outdoor nursery and under conditions which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged between 15 and 30° C. and night temperatures ranged between 14 and 20° C. Plants were pinched one time about three to four weeks after planting rooted cuttings. Plants were about four months old when the photographs and the description were taken.
