We claim:
1. A new and distinct cultivar of New Guinea Impatiens plant as
shown and described herein.
Description
Genus and species: Impatiens hybrida hort.
Variety denomination: `SAKIMP027`.
BACKGROUND OF THE NEW PLANT
The present invention comprises of a new and distinct cultivar of
New Guinea Impatiens, botanically known as Impatiens hybrida hort,
and referred to by the variety name `SAKIMP027`. Impatiens variety
`SAKIMP027` originated from a hybridization in Misato, Japan
between the female Impatiens line `NE-4391`, an unpatented
proprietary Impatiens breeding line with a white flower color and
the male Impatiens line `H-10UA`, an unpatented proprietary
Impatiens breeding line with a white flower color.
In October 2008, the female parent line `NE-4391` and the male
parent line `H-10UA` were crossed and a population of F.sub.1
plants was created. The F.sub.1 plants were evaluated in Misato,
Japan in an open field trial. The criteria for plant selection
included a beautiful white flower color, strong root system and a
compact plant growth habit. At the completion of the trial, one
single-plant selection was made based on the aforementioned
criteria and vegetatively propagated. From May to August 2010, the
selection was evaluated in an open field in Misato, Japan. The
selection subsequently was named `SAKIMP027`. The selection has
been asexually propagated by means of vegetative cuttings at
Salinas, Calif., and has been found to retain all of its unique
characteristics and reproduce true to type in successive
generations though such vegetative propagation.
SUMMARY
The following are the most outstanding and distinguishing
characteristics of this new variety when grown under normal
horticultural practices in Salinas, Calif. 1. White flower color;
2. Strong root system; and 3. A compact plant growth habit.
DESCRIPTION OF THE PHOTOGRAPHS
This Impatiens plant is illustrated by the accompanying photographs
which show the plant's overall plant habit including form, foliage,
and flowers. The photographs are of a four-month-old plant grown in
Salinas, Calif. under greenhouse conditions in the spring of 2012.
The colors shown are as true as can be reasonably obtained by
conventional photographic procedures.
FIG. 1 shows the overall plant habit of the plant grown in a
pot.
FIG. 2 shows a close-up of the mature inflorescence of the
plant.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `SAKIMP027`. The data which define these
characteristics were collected from asexual reproductions carried
out in Salinas, Calif. Data was collected on four-month-old plants
grown under greenhouse conditions in Salinas, Calif. in the summer
of 2012. Color references are to The R.H.S. Colour Chart of The
Royal Horticultural Society of London (R.H.S.), 4.sup.th edition
(2001). Classification: Family.--Balsaminaceae.
Botanical.--Impatiens interspecific cross (Impatiens hybrida hort).
Common.--Impatiens. Designation.--`SAKIMP027`. Parentage: Female
parent.--Proprietary Impatiens line `NE-4391` (unpatented). Male
parent.--Proprietary Impatiens line `H-10UA` (unpatented). Growth:
Time to produce a rooted cutting.--About 4 weeks. Environmental
conditions for plant growth.--The terminal 1.0 to 1.5 inches of an
actively growing stem was excised. The vegetative cuttings were
propagated in five to six weeks. The base of the cuttings were
dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N Grow (1
solution:9 water) root inducing solution immediately prior to
sticking into the cell trays. Cuttings were stuck into plastic cell
trays having 98 cells, and containing a moistened peat moss-based
growing medium. The cuttings were misted with water from overhead
for 10 seconds every 30 minutes until sufficient roots were formed.
Rooted cuttings were transplanted and grown in 6-inch plastic pots
in a glass greenhouse located in Salinas, Calif. Pots contained a
peat moss-based growing medium. Soluble fertilizer containing 20%
nitrogen, 10% phosphorus and 20% potassium was applied once a day
or every other day by overhead irrigation. Plants were fertilized
every 2 to 3 days, 2 times in consecutive applications and then
given one clear water application. Pots were top-dressed with a
dry, slow release fertilizer containing 14% nitrogen, 14%
phosphorus and 14% potassium. The typical average air temperature
was 24.degree. C. Time to bloom from propagation: 6 to 8 weeks.
