Claims
It is claimed:
1. A new and distinct Chrysanthemum plant named `Dochrysbumb` as
illustrated and described.
Description
Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: `DOCHRYSBUMB`.
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 `Dochrysbumb`.
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 807825, not patented, as the female, or
seed, parent with a proprietary selection of Chrysanthemum X
morifolium identified as code number 807744, 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 `Dochrysbumb`. These
characteristics in combination distinguish `Dochrysbumb` as a new
and distinct Chrysanthemum plant: 1. Upright to somewhat outwardly
spreading and uniformly and 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-sized
to large decorative-type inflorescences with dark yellow-colored
ray florets. 6. Freely and early flower habit. 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 have
larger inflorescences than plants of the female parent selection.
2. Ray florets of plants of the new Chrysanthemum are darker yellow
in color than ray florets of 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 are taller than
plants of the male parent selection. 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
dark yellow-colored ray florets whereas plants of the male parent
selection have inflorescences with bronze-colored ray florets.
Plants of the new Chrysanthemum can also be compared to plants of
Chrysanthemum X morifolium `Fichrysun`, not patented. In
side-by-side comparisons, plants of the new Chrysanthemum differ
primarily from plants of `Fichrysun` in the following
characteristics: 1. Plants of the new Chrysanthemum flower earlier
than plants of `Fichrysun`. 2. Plants of the new Chrysanthemum have
larger inflorescences than plants of `Fichrysun`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate 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 photographs 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 on the first sheet is a side perspective view of a
typical flowering plant of `Dochrysbumb` grown in a container.
The photograph on the second sheet is a close-up view of a typical
flowering plant of `Dochrysbumb`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and
measurements describe plants grown during the spring in 15.25-cm
containers in a polyethylene-covered greenhouse in Encinitas,
Calif. and under cultural practices typical of commercial potted
Chrysanthemum production. During the production of the plants, day
temperatures averaged 26.degree. C., night temperatures averaged
20.degree. C. and light levels averaged 4,500 lux. Plants were
propagated under long day/short night conditions and then grown
under short day/long night conditions to induce inflorescence
initiation and development. Plants were disbudded. Five plants were
grown per pot and plants were 14 weeks old when the photographs and
detailed description were taken. In the following description,
color references are made to The Royal Horticultural Society Colour
Chart, 2015 Sixth Edition, except where general terms of ordinary
dictionary significance are used. Botanical classification:
