Claims
We claim:
1. A new and distinct cultivar of Petunia-Calibrachoa hybrid plant
as illustrated and described herein.
Description
Genus and species: Petunia-Calibrachoa intergeneric hybrid.
Variety denomination: `SAKPXC017`.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of
Petunia-Calibrachoa (Petchoa) referred to by the variety name
`SAKPXC017`. Variety `SAKPXC017` originated from a hybridization in
Kakegawa, Japan in December 2011. The female parent was a
proprietary Petunia Hybrida line named `GY2-1E-6` (unpatented),
which had a yellow flower color and a mounding plant habit. The
male parent was a proprietary Calibrachoa Hybrida line named
`AM9-83A-1B-2A` (unpatented), which had a yellow flower color and a
compact plant habit.
In December 2011, the breeder made an initial cross between the
female and male breeding lines. In January 2012, 34 ovules were
obtained and ovule culture was done to rescue the embryo. In July
2012, 5 plants were obtained after the acclimatization process was
completed. Segregation in the F.sub.1 generation resulted in plants
having yellow, cream and brown flower colors with vein and mounding
or semi-mounding habits. The breeder selected a plant from the
group of plants that exhibited a yellow flower color that was well
blooming and had a mounding plant habit. The line was given the
experimental name `K2013-J-228`.
In August 2012, the selection was vegetatively propagated by
cuttings to produce rooted cuttings and plants of the selection
were cultivated evaluated in an open field. In November 2012, the
breeder observed the selected line to have its distinct
characteristics remain stable. In December 2012, the selection was
propagated again and plants were cultivated. In April 2013, the
breeder confirmed that the distinct characteristics of the
selection were fixed and stable. All breeding work was conducted at
Kakegawa Research station in Kakegawa Japan. The selection was
named `SAKPXC017`.
SUMMARY
The following are the most outstanding and distinguishing
characteristics of this new variety when grown under normal
horticultural practices in Salinas, Calif. 1. Light yellow flower
color with darker veins; and 2. A mounding plant habit.
DESCRIPTION OF THE PHOTOGRAPHS
This new Petunia-Calibrachoa 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
plant grown in Salinas, Calif. under greenhouse conditions. The
colors shown are as true as can be reasonably obtained by
conventional photographic procedures.

pot.
FIG. 2 shows a close-up of the buds, and flower, of the plant shown
in FIG. 1.
FIG. 3 shows the overall plant habit of a mature plant grown in a
pot.
FIG. 4 shows a close-up of the buds and flower of the plant shown
in FIG. 3.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `SAKPXC017`. Plants were five months from stick
date and two and a half months from transplant. Color references
are to The R.H.S. Colour Chart of The Royal Horticultural Society
of London (R.H.S.), 4.sup.th edition. Anatomic labels are from The
Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and

parent.--`GY2-1E-6` (unpatented). Male parent.--`AM9-83A-1B-2A`
(unpatented). Growth: 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), a 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. For the
first week, the cuttings were misted with water from overhead for
10 seconds every 30 minutes until sufficient roots were formed.

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. Pots
were top-dressed with a dry, slow release fertilizer containing 20%
nitrogen, 10% phosphorus and 18% potassium. The typical average air
temperature was 24.degree. C. Plant description: Habit.--Mounding.
