Claims
It is claimed:
1. A new and distinct Chrysanthemum plant named `Dommertrup` as
illustrated and described.
Description
Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: `DOMMERTRUP`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Chrysanthemum
plant, botanically known as Chrysanthemum X morifolium,
commercially grown as a garden Chrysanthemum plant, referred to as
code number 66569 in U.S. Provisional Patent Application Ser. No.
62/708,405 and hereinafter referred to by the name
`Dommertrup`.
The new Chrysanthemum plant is a product of a planned breeding
program conducted by the Inventor in Fareham, Hampshire, United
Kingdom. The objective of the breeding program is to create new
garden Chrysanthemum plants with numerous attractive
inflorescences.
The new Chrysanthemum plant originated from a cross-pollination
made in January, 2013 by the Inventor in Fareham, Hampshire, United
Kingdom of a proprietary selection of Chrysanthemum X morifolium
identified as code number 802483, not patented, as the female, or
seed, parent with a proprietary selection of Chrysanthemum X
morifolium identified as code number 802067, not patented, as the
male, or pollen, parent. The new Chrysanthemum 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 Fareham, Hampshire, United Kingdom in
September, 2013.
Asexual reproduction of the new Chrysanthemum plant by terminal
vegetative cuttings was first conducted in Fareham, Hampshire,
United Kingdom in December, 2013. Asexual reproduction by terminal
vegetative cuttings has shown that the unique features of this new
Chrysanthemum plant are stable and reproduced true to type in
successive generations.
SUMMARY OF THE INVENTION
Plants of the new Chrysanthemum have not been observed under all
possible combinations of environmental conditions and cultural
practices. The phenotype may vary somewhat with variations in
environmental conditions 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 `Dommertrup`. These
characteristics in combination distinguish `Dommertrup` as a new
and distinct Chrysanthemum plant: 1. Upright to outwardly spreading
and uniformly and broadly mounded plant habit. 2. Moderately
vigorous growth habit. 3. Freely branching habit; dense and full
plant form. 4. Uniform and freely flowering habit. 5.
Decorative-type inflorescences with light purple-colored ray
florets. 6. Mid-season flowering habit, grown under natural season
conditions, plants begin flowering in early September in the United
Kingdom. 7. Good garden performance.
Plants of the new Chrysanthemum can be compared to plants of the
female parent selection. Plants of the new Chrysanthemum differ
primarily from plants of the female parent selection in the
following characteristics: 1. Plants of the new Chrysanthemum are
larger than plants of the female parent selection. 2. Plants of the
new Chrysanthemum have larger inflorescences than plants of the
female parent selection.
Plants of the new Chrysanthemum can be compared to plants of the
male parent selection. Plants of the new Chrysanthemum differ
primarily from plants of the male parent selection in the following
characteristics: 1. Plants of the new Chrysanthemum have decorative
type inflorescences whereas plants of the male parent selection
have semi-decorative type inflorescences. 2. Plants of the new
Chrysanthemum and the male parent selection differ in ray floret
color as plants of the new Chrysanthemum have inflorescences with
light purple-colored ray florets whereas plants of the male parent
selection have inflorescences with coral pink-colored ray
florets.
Plants of the new Chrysanthemum can be compared to plants of
Chrysanthemum X morifolium `Fichrysunaub`, disclosed in U.S. Plant
patent application Ser. No. 15/732,517. In side-by-side
comparisons, plants of the new Chrysanthemum differ primarily from
plants of `Fichrysunaub` in the following characteristics: 1.
Plants of the new Chrysanthemum flower later than plants of
`Fichrysunaub`. 2. Plants of the new Chrysanthemum and
`Fichrysunaub` differ in ray floret color as plants of the new
Chrysanthemum have inflorescences with light purple-colored ray
florets whereas plants of `Fichrysunaub` have inflorescences with
deep red purple-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of
the new Chrysanthemum plant showing the colors as true as it is
reasonably possible to obtain in colored reproductions of this
type. Colors in the photograph may differ slightly from the color
values cited in the detailed botanical description which accurately
describe the colors of the new Chrysanthemum plant.
The photograph is a top perspective view of a typical flowering
plant of `Dommertrup` grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and
measurements describe plants grown during the winter in 19-cm
containers in a glass-covered greenhouse in Fareham, Hampshire,
United Kingdom and under cultural practices typical of commercial
garden Chrysanthemum production. During the production of the
plants, day and night temperatures ranged from 17.degree. C. to
21.degree. C. and light levels averaged 6,000 lux. Plants were
grown under long day/short night conditions for about seven weeks
(including propagation period) and then grown under short day/long
night conditions to induce inflorescence initiation and
development. Plants were 14 weeks old when the photograph and
detailed description were taken. In the following description,
color references are made to The Royal Horticultural Society Colour
Chart, Fifth Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification:
