Description

Genus and species: Calibrachoa spp.

Variety denomination: ‘SAKCAL108’.

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 ‘SAKCAL108’. ‘SAKCAL108’ originated from a hybridization in Kakegawa, Japan in 2007 between the female Calibrachoa line ‘7B-15A’, an unpatented proprietary hybrid Calibrachoa breeding line having a white flower color and semi-mounding growth habit and the male Calibrachoa line ‘6dw-1A-1B’, an unpatented proprietary hybrid Calibrachoa breeding line with a white flower color and compact growth habit.

In February 2007, the female parent line ‘7B-15A’ and the male parent line ‘6dw-1A-1B’ were crossed and 200 seeds were obtained. The F1 seed were sown in a greenhouse, cultivated, and plant lines were produced with white flower color with compact and vigorous growth habits.

In May 2007 a single plant was selected within the F1 plants that had a white flower color and a compact growth habit and designated ‘K2009-104’.

In July 2007, ‘K2009-104’ was vegetatively propagated, cultivated, and evaluated. In October 2007, ‘K2009-104’ was confirmed to be fixed and stable. In February 2008 ‘K2009-104’ was further propagated and cultivated to reconfirm the line's stability. ‘K2009-104’ was subsequently designated ‘SAKCAL108’ and found to have its unique characteristics reproduce true to type in successive generations of asexual vegetative propagation via vegetative cuttings in Salinas, Calif.

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; and
    • 2. A compact plant growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

This 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 four-month-old plant grown in Salinas, Calif. under greenhouse conditions in the summer of 2012. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

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 ‘SAKCAL108’. 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.), 4th edition (2001).

  • Classification:
      • Family.—Solanaceae.

      • Common.—Calibrachoa.
      • Designation.—‘SAKCAL108’.
  • Parentage:
      • Female parent.—Proprietary hybrid Calibrachoa line ‘7B-15A’ (unpatented).
      • Male parent.—Proprietary hybrid Calibrachoa line ‘6dw-1A-1B’ (unpatented).
  • Growth:
      • Time to produce a rooted cutting.—About 6 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 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.
