Abstract

A new Petunia-Calibrachoa hybrid plant particularly distinguished by having a pink with red-purple vein flower color and mounding plant growth habit is disclosed.

Description

Genus and species: Petunia-Calibrachoa intergeneric hybrid.
Variety denomination: ‘SAKPXC008’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of Petunia-Calibrachoa (Petchoa) referred to by the variety name ‘SAKPXC008’. Variety ‘SAKPXC008’ originated from a hybridization in Kakegawa, Japan in December 2006. The male parent was a proprietary hybrid Calibrachoa line named ‘5Bdw-7b-V1’ (unpatented), which had a pink flower with unknown vein color and a creeping plant habit. The female parent was a proprietary hybrid petunia line named ‘AM6-64A’ (unpatented), which had a pink flower color with a yellow throat and a mounding plant habit.
In December 2006, an F1 generation from the initial hybridization was grown and approximately 70 seeds were obtained. In February 2007, 70 seeds were sown and the plants were cultivated in a greenhouse. Segregation in the F1 generation resulted in plants that had pink flower color with vein, rose flower color with vein and either a mounding or semi-creeping plant growth habit. In May 2007, a plant was selected that exhibited a pink with red-purple vein flower color and a mounding plant growth habit from the group of plants.
In July 2007, plants were vegetatively propagated to produce rooted cuttings. The plants were transplanted to an open field and evaluated for flower color and plant growth habit. A plant was selected that had a pink flower color, an excellent blooming ability and semi-creeping plant growth habit. The selection was propagated and plants of the selection were cultivated and evaluated in an open field. In November 2007, the selection was observed to have its distinct characteristics remain stable. In February 2008, the selection was propagated again and plants were cultivated. In May 2008, it was confirmed that the distinct characteristics of the selection were fixed and stable. The selection was given the experimental name ‘K2008-J-222’. The selection was later named ‘SAKPXC008’ and was found to reproduce true to type in successive generations of asexual propagation via 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. Pink with red-purple vein flower color; and
    • 2. Mounding plant growth 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 three-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 the mature inflorescence of the plant.
 DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive characteristics of ‘SAKPXC008’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on three-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.), 4th edition.

  • Growth:
      • Time to produce a rooted cutting.—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 four 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. For the first week, the cuttings were misted with water from overhead for 20 seconds, one time per hour. For the second week, the cuttings were misted one time every 2 hours for 10 seconds. After that time, the cuttings were misted occasionally until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter 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° C.
