Claims
It is claimed:
1. A new and distinct Chrysanthemum plant named `Dochryspur` as
illustrated and described.
Description
Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: `DOCHRYSPUR`.
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 and hereinafter
referred to by the name `Dochryspur`.
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, 2014 by the Inventor in Fareham, Hampshire, United
Kingdom of a proprietary selection of Chrysanthemum X morifolium
identified as code number 807686, not patented, as the female, or
seed, parent with a proprietary selection of Chrysanthemum X
morifolium identified as code number 807678, 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, 2014.
Asexual reproduction of the new Chrysanthemum plant by terminal
vegetative cuttings was first conducted in Fareham, Hampshire,
United Kingdom in December, 2014. 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 `Dochryspur`. These
characteristics in combination distinguish `Dochryspur` as a new
and distinct Chrysanthemum plant: 1. Upright to outwardly spreading
and uniformly mounded plant habit. 2. Medium in height and
moderately vigorous growth habit. 3. Freely branching habit; dense
and full plant form. 4. Uniform and freely flowering habit. 5.
Large decorative-type inflorescences with dark red purple-colored
ray florets. 6. Grown under controlled daylength/nyctoperiods,
flowering response time is about 50 days.
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 ray floret
color as of the female parent selection have bronze-colored ray
florets.
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 time to
flower as plants of the male parent selection flower about two days
earlier.
Plants of the new Chrysanthemum can be compared to plants of
Chrysanthemum X morifolium `Chrystal Aubergine`, not patented. In
side-by-side comparisons, plants of the new Chrysanthemum differ
primarily from plants of `Chrystal Aubergine` in time to flower as
plants of the new Chrysanthemum flower about four days later than
plants of `Chrystal Aubergine`. In addition, plants of the new
Chrysanthemum are taller than plants of `Chrystal Aubergine`.
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
`Dochryspur` grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and
measurements describe plants grown during the winter 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
propagated under long day/short night conditions for two weeks and
then grown under short day/long night conditions to induce
inflorescence initiation and development. Plants were nine 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.
