Ser. No.: 62/919,611
Inventor/Applicant hereby claim the benefit of this provisional
U.S. Patent Application.
STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT &
ASSIGNEE
A Columbian Plant Breeder's Rights application for the instant
plant was filed by the Assignee, Deliflor Royalties B.V. of
Maasdijk, The Netherlands on Aug. 24, 2018, application number
A182425. Foreign priority is not claimed to this application.
The Inventor/Applicant and Assignee assert that no publications nor
advertisements relating to sales, offers for sale or public
distribution occurred more than one year prior to the effective
filing date of this application. Any information about the claimed
plant would have been obtained from a direct or indirect disclosure
from the Inventor/Applicant and/or the Assignee. Inventor/Applicant
and Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1)
for disclosure and/or sales prior to the filing date but less than
one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Chrysanthemum plant, botanically known as Chrysanthemum x
morifolium, typically grown as a cut flower Chrysanthemum and
hereinafter referred to by the name `DLFSOLE2`.
The new Chrysanthemum 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 cut flower
Chrysanthemum plants with numerous attractive inflorescences.
The new Chrysanthemum plant is a naturally-occurring whole plant
mutation of Chrysanthemum x morifolium `Delisolemio`, not patented.
The new Chrysanthemum plant was discovered and selected as a single
flowering plant from within a population of plants of `Delisolemio`
in a controlled greenhouse environment in Maasdijk, The Netherlands
in September, 2015.
Asexual reproduction of the new Chrysanthemum plant by vegetative
terminal cuttings since September, 2016 in Maasdijk, The
Netherlands, has shown that the unique features of this new
Chrysanthemum plant are stable and reproduced true to type in
successive generations of asexual reproduction.
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 `DLFSOLE2`. These
characteristics in combination distinguish `DLFSOLE2` as a new and
distinct Chrysanthemum plant: 1. Upright plant habit; vigorous
growth habit. 2. Large dark green-colored leaves. 3. Uniform
flowering habit. 4. Strong upright flowering stems typically grown
as a single-stem (disbudded) cut flower. 5. Decorative-type
inflorescences with bright yellow-colored ray florets. 6.
Relatively resistant to Fusarium oxysporum f. sp. chrysanthemi and
Puccinia horiana strain PhNL1.
Plants of the new Chrysanthemum differ from plants of the mutation
parent, `Delisolemio`, in ray floret color as plants of the new
Chrysanthemum have bright yellow-colored ray florets whereas plants
of `Delisolemio` have greyed orange-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of
Chrysanthemum X morifolium `Zembla Yellow`, disclosed in U.S. Plant
Pat. No. 14,733. In side-by-side comparisons, plants of the new
Chrysanthemum differ primarily from plants of `Zembla Yellow` in
ray floret color as ray florets of plants of the new Chrysanthemum
are brighter yellow in color than ray florets of plants of `Zembla
Yellow`. In addition, ray florets of plants of the new
Chrysanthemum are more incurved than ray florets of plants of
`Zembla Yellow`.
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. The photograph on the first sheet (FIG. 1 of 2) comprises a
side perspective view of a typical flowering stem of `DLFSOLE2`
grown as a disbud-type cut flower.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view
of lower (top of the photographic sheet) and upper (bottom of the
photographic sheet) surfaces of typical inflorescences (left) and
leaves (right).
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and
measurements describe plants grown during the winter in ground beds
in a glass-covered greenhouse in Maasdijk, The Netherlands and
under cultural practices typical of commercial cut Chrysanthemum
production. Plants were initially given long day/short night
treatments followed by short day/long night treatments to induce
flower initiation and development. During the production of the
plants, day temperatures ranged from 18.degree. C. to 25.degree.
C., night temperatures ranged from 2.degree. C. to 20.degree. C.
and light levels averaged 8 klux. Plants were grown as single-stem
disbud-type plants and were nine weeks old when the photographs and
the description were taken. 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:
