Claims
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named `Yosun
City`, as illustrated and described.
Description
Botanical designation: Chrysanthemum.times.morifolium.
Cultivar denomination: `Yosun City`.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Chrysanthemum plant, botanically known as
Chrysanthemum.times.morifolium and hereinafter referred to by the
name `Yosun City`.
The new Chrysanthemum is a product of a planned breeding program
conducted by the Inventor in Fareham, Hampshire, United Kingdom.
The objective of the program is to create or discover new potted
Chrysanthemum cultivars that are suitable for year-round production
with uniform plant growth habit, good vigor and strong branching
habit, numerous inflorescences, desirable inflorescence form and
floret colors, fast and uniform flowering response, and good
postproduction longevity.
The new Chrysanthemum originated from a cross-pollination made in
January, 2001 in Fareham, Hampshire, United Kingdom, of a
proprietary selection of Chrysanthemum.times.morifolium identified
as code number P130E 1, not patented, as the female, or seed,
parent with the Chrysanthemum.times.morifolium cultivar Los Alamos,
not patented, as the male, or pollen, parent. The new Chrysanthemum
was discovered and selected by the Inventor as a single flowering
plant within the progeny of the stated cross-pollination grown in a
controlled environment in Fareham, Hampshire, United Kingdom in
January, 2001. The selection of this plant was based on its uniform
plant growth habit, good vigor and strong branching habit,
desirable inflorescence form and floret colors, fast and uniform
flowering response, and good postproduction longevity.
Asexual reproduction of the new Chrysanthemum by vegetative tip
cuttings was first conducted in Fareham, Hampshire, United Kingdom
in January, 2001. Asexual reproduction by cuttings has shown that
the unique features of this new Chrysanthemum are stable and
reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Yosun City has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment such as temperature, daylength, and/or
light level, without, however, any variance in genotype.
The following traits have been repeatedly observed and are
determined to be the unique characteristics of `Yosun City`. These
characteristics in combination distinguish `Yosun City` as a new
and distinct Chrysanthemum: 1. Uniform and somewhat outwardly
spreading plant habit. 2. Strong and freely branching growth habit.
3. Dark green-colored foliage. 4. Uniform flowering response and
habit. 5. Typically grown as a spray-type. 6. Early flowering,
eight week response time. 7. Large daisy-type inflorescences with
elongated oblong-shaped ray florets. 8. Red and yellow bi-colored
ray florets. 9. Excellent postproduction longevity with plants
maintaining good substance and color for about four weeks in an
interior environment.
Plants of the new Chrysanthemum can be compared to plants of the
female parent selection. Plants of the new Chrysanthemum differ
from plants of the female parent selection primarily in ray floret
color as plants of the female parent selection have red-colored ray
florets. In addition, plants of the new Chrysanthemum flowered
about three or four days later than plants of the female parent
selection.
Plants of the new Chrysanthemum can be compared to plants of the
male parent, the cultivar Los Alamos. Plants of the new
Chrysanthemum differ from plants of the cultivar Los Alamos in the
following characteristics: 1. Plants of the new Chrysanthemum are
larger than plants of the cultivar Los Alamos. 2. Plants of the new
Chrysanthemum have larger inflorescences than plants of the
cultivar Los Alamos. 3. Plants of the new Chrysanthemum flower
about three to four days earlier than plants of the cultivar Los
Alamos.
Plants of the new Chrysanthemum can be compared to plants of the
cultivar Yobaton Rouge, disclosed in U.S. Plant Pat. No. 11,283. In
side-by-side comparisons conducted in Fareham, Hampshire, United
Kingdom, plants of the new Chrysanthemum differed from plants of
the cultivar Yobaton Rouge in the following characteristics: 1.
Plants of the new Chrysanthemum were larger than plants of the
cultivar Yobaton Rouge. 2. Plants of the new Chrysanthemum had
larger inflorescences than plants of the cultivar Yobaton Rouge. 3.
Plants of the new Chrysanthemum flowered about three to four days
earlier than plants of the cultivar Yobaton Rouge.
Plants of the new Chrysanthemum can also be compared to plants of
the cultivar Cedar Falls, disclosed in U.S. Plant Pat. No. 13,068.
In side-by-side comparisons conducted in Fareham, Hampshire, United
Kingdom, plants of the new Chrysanthemum differed from plants of
the cultivar Cedar Falls in the following characteristics: 1.
Plants of the new Chrysanthemum were shorter than plants of the
cultivar Cedar Falls. 2. Plants of the new Chrysanthemum had more
pointed ray florets than plants of the cultivar Cedar Falls. 3.
Plants of the new Chrysanthemum flowered about one week earlier
than plants of the cultivar Cedar Falls.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

this type. Colors in the photographs may differ from the color
values cited in the detailed botanical description which accurately
describe the colors of the new Chrysanthemum.
The photograph on the first sheet comprises a side perspective view
of typical flowering plants of `Yosun City` grown as
spray-types.
The photograph on the second sheet comprises a close-up view of
typical inflorescences of `Yosun City` grown as spray-types.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The
Royal Horticultural Society Colour Chart, 1995 Edition, except
where general terms of ordinary dictionary significance are used.
The aforementioned photographs, following observations and
measurements describe plants grown and flowered during the spring
in Salinas, Calif., in a fiberglass-covered greenhouse and under
conditions which approximate those generally used in commercial
potted Chrysanthemum production. During the production of these
plants, the following conditions were measured: day temperatures,
21 to 27.degree. C.; night temperatures, 17 to 19.degree. C.; and
light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings
were directly stuck in 15-cm containers, exposed to long day/short
night conditions, and pinched once about two weeks later. At the
time of the pinch, the photoinductive short day/long night
treatments were initiated. Plants used for the description were
grown as spray-types. Measurements and numerical values represent
averages of typical flowering plants. Botanical classification:
