Claims
It is claimed:
1. A new and distinct cultivar of Chrysanthemum plant named
`Yobrianna`, as illustrated and described.
Description
Botanical classification/cultivar designation:
Chrysanthemum.times.morifolium cultivar Yobrianna.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Chrysanthemum plant, botanically known as
Chrysanthemum.times.morifolium, commercially known as a garden-type
Chrysanthemum and hereinafter referred to by the name
`Yobrianna`.
The new cultivar is a product of a planned breeding program
conducted by the Inventor in Fareham, Hants, United Kingdom. The
objective of the breeding program is to create new garden-type
Chrysanthemum cultivars having inflorescences with desirable
inforescence forms, attractive floret coloration and good garden
performance.
The new Chrysanthemum originated from a cross-pollination made in
March, 1998 in Fareham, Hants, United Kingdon, of the
Chrysanthemum.times.morifolium cultivar Pidoul, disclosed in U.S.
Plant Pat. No. 10,218, as the female, or seed, parent with a
proprietary selection of Chrysanthemum.times.morifolium identified
as code number G137A1, 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, Hants, United Kingdom in September, 1998. The selection of
this plant was based on its desirable inflorescence form,
attractive floret coloration and good garden performance.
Asexual reproduction of the new cultivar by terminal vegetative
cuttings in a controlled environment in Fareham, Hants, United
Kingdom since December, 1998, 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 Yobrianna has not been observed under all possible
environmental conditions. The phenotype may vary somewhat with
variations in environment 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 `Yobrianna`. These
characteristics in combinaton distinguish `Yobrianna` as a new and
distinct cultivar of Chrysanthemum: 1. Upright, outwardly spreading
and rounded plant habit. 2. Freely branching habit; dense and full
plants. 3. Uniform and freely flowering habit. 4. Small daisy-type
inflorescences with elongated oblong-shaped ray florets. 5.
White-colored ray florets and bright yellow-colored disc florets.
6. Natural season flowering in mid-October in the Northern
Hemisphere. 7. Good garden performance.
In side-by-side comparisons conducted in Fareham, Hants, United
Kingdom, plants of the new Chrysanthemum differed from plants of
the female parent, the cultivar Pidoul, in the following
characteristics: 1. Plants of the new Chrysanthemum were larger
than plants of the cultivar Pidoul. 2. Plants of the new
Chrysanthemum flowered later than plants of the cultivar
Pidoul.
In side-by-side comparisons conducted in Fareham, Hants, United
Kingdom, plants of the new Chrysanthemum differed from plants of
the male parent, the proprietary selection identified as code
number G137A1, in the following characteristics: 1. Inflorescences
of plants of the new Chrysanthemum had fewer ray florets than
inflorescences of plants of the male parent selection. 2. Plants of
the new Chrysanthemum and the male parent selection differed in ray
floret coloration as plants of the male parent selection had creamy
white-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the
Chrysanthemum cultivar Shepherd, disclosed in U.S. Plant Pat. No.
13,371. In side-by-side comparisons conducted in Alva, Fla. under
natural season conditions, plants of the new Chrysanthemum differed
from plants of the cultivar Shepherd in the following
characteristics: 1. Plants of the new Chrysanthemum were larger
than plants of the cultivar Shepherd. 2. Plants of the new
Chrysanthemum had slightly smaller inflorescences than plants of
the cultivar Shepherd. 3. Plants of the new Chrysanthemum flowered
about two weeks later than plants of the cultivar Shepherd.
Plants of the new Chrysanthemum can also be compared to plants of
the Chrysanthemum cultivar Papiro, disclosed in U.S. Plant Pat. No.
12,998. In side-by-side comparisons conducted in Alva, Fla. under
natural season conditions, plants of the new Chrysanthemum differed
from plants of the cultivar Papiro in the following
characteristics: 1. Plants of the new Chrysanthemum were larger and
had a more rounded crown than plants of the cultivar Papiro. 2.
Plants of the new Chrysanthemum had larger inflorescences than
plants of the cultivar Papiro. 3. Plants of the new Chrysanthemum
flowered about 10 to 14 days earlier than plants of the cultivar
Papiro. 4. Plants of the new Chrysanthemum and the cultivar Papiro
differed in ray floret coloration as plants of the cultivar Papiro
had creamy white-colored ray florets.

of a typical flowering plant of `Yobrianna` grown in a
container.
The photograph on the second sheet comprises a close-up view of
typical inflorescences of the cultivar `Yobrianna`.
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 following observations and measurements describe plants grown
in Leamington, Ontario, Canada during the late summer and fall in
an outdoor nursery and under conditions and practices which
approximate those generally used in commercial garden-type
Chrysanthemum production. One cutting was planted in a 15.25-cm
container in mid-July. During the production of the plants, plants
were exposed to natural season photoperiodic conditions with day
temperatures averaging 26.degree. C. and night averaging 18.degree.

flowering plants. Botanical classification:
