Description

Genus and species: Calibrachoa spp.

Variety denomination: ‘SAKCAL112’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Calibrachoa plant, botanically known as Calibrachoa spp., and referred to by the variety name ‘SAKCAL112’. ‘SAKCAL112’ originated from a hybridization made in 2008 in Kakegawa, Japan. The female parent was the proprietary hybrid Calibrachoa breeding line named ‘7-3B-1A’ and had a lavender, pink and rose flower color, large flower size and a mounding plant growth habit. The male parent was the proprietary hybrid Calibrachoa breeding line named ‘7B-16A-1’ characterized by its lavender flower color, medium flower size and a compact plant growth habit.

In November 2008, the parental lines ‘7-3B-1A’ and ‘7B-16A-1’ were crossed and 200 seeds were obtained. In February 2009, the F1 seed was sown in the greenhouse, cultivated and plant lines were produced with flower colors of rose, pink and lavender with a mounding and creeping plant growth habit. In May 2009, four plant lines were selected within the F1 plants that had lavender flowers and a compact plant growth habit. In June 2009, the four plant lines were intercrossed and 2,500 seeds were obtained from the group of F2 plants.

In August 2009, 500 seeds were sown in the greenhouse, cultivated and plant lines were produced with flower colors of lavender with a mounding and compact plant growth habit. In November 2009, the line ‘K2010-062’ was selected for its lavender flower color and compact plant growth habit.

In February 2010, line ‘K2010-062’ was first vegetatively propagated, cultivated and evaluated. In April 2010, line ‘K2010-062’ was confirmed to be fixed and stable. In July 2010, line ‘K2010-062’ was propagated and cultivated again to reconfirm the lines' stability. In November 2010, the line was confirmed to be fixed and stable. The line was subsequently named ‘SAKCAL112’ and its unique characteristics were found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Salinas, Calif. Asexual propagation was performed via excising the terminal 1.0 inches to 1.5 inches of an actively growing stem of the variety.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Salinas, Calif.

    • 1. Lavender flower color;
    • 2. Compact growth habit; and
    • 3. Large flower size.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKCAL112’. 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 2013. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4th edition (2001).

  • Classification:

      • Botanical.—Calibrachoa spp.
      • Common.—Calibrachoa.
      • Designation.—‘SAKCAL112’.
  • Parentage:
      • Female parent.—Proprietary hybrid Calibrachoa line ‘7-3B-1A’ (unpatented).
      • Male parent.—Proprietary hybrid Calibrachoa line ‘7B-16A-1’ (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), 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. 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 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.
