Claims
It is claimed:
1. A new and distinct Chrysanthemum plant named `Domchryrom` as
illustrated and described.
Description
Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: `DOMCHRYROM`.
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 potted Chrysanthemum plant, referred to as
code number 65896 in U.S. Provisional Patent Application Ser. No.
62/708,405 and hereinafter referred to by the name
`Domchryrom`.
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
potted Chrysanthemum plants with numerous attractive
inflorescences.
The new Chrysanthemum plant originated from a cross-pollination
made in January, 2015 by the Inventor in Fareham, Hampshire, United
Kingdom of a proprietary selection of Chrysanthemum X morifolium
identified as code number 808475, not patented, as the female, or
seed, parent with a proprietary selection of Chrysanthemum X
morifolium identified as code number P0043, 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, 2015.
Asexual reproduction of the new Chrysanthemum plant by terminal
vegetative cuttings was first conducted in Fareham, Hampshire,
United Kingdom in December, 2015. 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 `Domchryrom`. These
characteristics in combination distinguish `Domchryrom` as a new
and distinct Chrysanthemum plant: 1. Upright to outwardly spreading
and uniformly mounded plant habit. 2. Moderately vigorous growth
habit. 3. Freely branching habit; dense and full plant form. 4.
Uniform and freely flowering habit. 5.Medium to large decorative
type inflorescences with red purple and light purple-colored ray
florets. 6. Response time about 50 days under controlled
photoperiodic treatments. 7. Good postproduction longevity.
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
flower about four days earlier than plants of the female parent
selection. 2. Plants of the new Chrysanthemum have decorative type
inflorescences whereas plants of the female parent selection have
semi-decorative type inflorescences.
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 inflorescence
form as plants of the new Chrysanthemum have decorative type
inflorescences whereas plants of the male parent selection have
anemone type inflorescences.
Plants of the new Chrysanthemum can be compared to plants of
Chrysanthemum X morifolium `Chrystal Pink`, not patented. In
side-by-side comparisons, plants of the new Chrysanthemum differ
primarily from plants of `Chrystal Pink` in the following
characteristics: 1. Plants of the new Chrysanthemum have decorative
type inflorescences whereas plants of `Chrystal Pink` have
semi-decorative type inflorescences. 2. Plants of the new
Chrysanthemum and `Chrystal Pink` differ in ray floret color as
plants of the new Chrysanthemum have inflorescences with red purple
and light purple-colored ray florets whereas plants of `Chrystal
Pink` have inflorescences with light 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 side perspective view of a typical flowering
plant of `Domchryrom` grown in a 14-cm container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and
measurements describe plants grown during the spring in 14-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 two weeks and
then grown under short day/long night conditions to induce
inflorescence initiation and development. Plants were ten 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.
