Claims
It is claimed:
1. A new and distinct Dahlia plant named `BKDAMRD` as illustrated
and described.
Description
Botanical designation: Dahlia hybrida.
Cultivar denomination: `BKDAMRD`.
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 `BKDAMRD`.
The new Dahlia plant is a product of a planned breeding program
conducted by the Inventor in Maasdijk, The Netherlands. The
objective of the breeding program is to create new sturdy container
Dahlia plants that have a freely basal branching habit, and large
inflorescences with attractive ray floret coloration.
The new Dahlia plant originated from an open-pollination in
September, 2012 in Maasdijk, The Netherlands of a proprietary
selection of Dahlia hybrida identified as code number 4002145, not
patented, as the female, or seed, parent with an unknown selection
of Dahlia hybrida as the male, or pollen, parent. The new Dahlia
plant was discovered and selected by the Inventor as a single
flowering plant from within the progeny of the stated
open-pollination in a controlled greenhouse environment in
Maasdijk, The Netherlands in October, 2013.
Asexual reproduction of the new Dahlia plant by terminal cuttings
in a controlled greenhouse environment in Maasdijk, The Netherlands
since February, 2014 has shown that the unique features of this new
Dahlia plant are stable and reproduced true to type in successive
generations.
SUMMARY OF THE INVENTION
Plants of the new Dahlia have not been observed under all possible
combinations of environmental conditions and cultural conditions.
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 `BKDAMRD`. These
characteristics in combination distinguish `BKDAMRD` as a new and
distinct Dahlia plant: 1. Broadly upright and sturdy plant habit.
2. Freely basal branching habit; dense and bushy growth habit. 3.
Dark green-colored leaves. 4. Large semi-double inflorescences with
bright red-colored ray florets.
Plants of the new Dahlia differ primarily from plants of the female
parent selection in the following characteristics: 1.
Inflorescences of plants of the new Dahlia are larger than
inflorescences of plants of the female parent selection. 2. Plants
of the new Dahlia and the female parent selection differ in ray
floret color as plants of the female parent selection have
yellow-colored ray florets.
Plants of the new Dahlia can be compared to plants of Dahlia
variabilis `Carolina Burgundy`, disclosed in U.S. Plant Pat. No.
13,635. In side-by-side comparisons, plants of the new Dahlia
differ from plants of `Carolina Burgundy` in the following
characteristics: 1. Inflorescences of plants of the new Dahlia have
more ray florets than inflorescences of plants of `Carolina
Burgundy`. 2. Plants of the new Dahlia and `Carolina Burgundy`
differ in ray floret color as plants of `Carolina Burgundy` have
dark red purple-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of
the new Dahlia 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 Dahlia plant.
The photograph on the first sheet comprises a side perspective view
of a typical flowering plant of `BKDAMRD` grown in a container.
The photograph on the second sheet is a close-up view of a typical
inflorescence of `BKDAMRD`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and the following observations and
measurements describe plants grown during the winter in 12-cm
containers in a glass-covered greenhouse in Maasdijk, The
Netherlands and under cultural practices typical of commercial
Dahlia production. During the production of the plants, day and
night temperatures ranged from 17.degree. C. to 19.degree. C.
Plants were pinched one time and were nine weeks old when the
photographs and description were taken. To induce inflorescence
initiation and development, plants were grown under short
nyctoperiod (long day) conditions. In the following description,
color references are made to The Royal Horticultural Society Colour
Chart, 2015 Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification: Dahlia
hybrida `BKDAMRD`. Parentage: Female, or seed, parent.--Proprietary
