Description

Genus and species: Portulaca oleracea.

Variety denomination: ‘SAKPOR005’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Portulaca plant, botanically known as Portulaca oleracea, and referred to by the variety name ‘SAKPOR005’. Portulaca line ‘SAKPOR005’ originated from a hybridization in Kakegawa, Japan in 2006 between the female Portulaca line ‘Mo04-19A-V2’, an unpatented proprietary Portulaca breeding line having a white flower color and bushy growth habit and the male Portulaca line ‘Ma01-3A-1B1’, an unpatented proprietary Portulaca breeding line with a gold flower color and bushy growth habit.

In August 2006, the female parent line ‘Mo04-19A-V2’ and male parent line ‘Ma01-3A-1B1’ were crossed and F1 seeds were obtained. In May 2007, the F1 seed was sown in the greenhouse, cultivated and plant lines were produced with pink and lemon colored flowers with a bushy plant habit. The plants were evaluated and plant line ‘K2008-107’ was selected for its lemon yellow flower color, flower blooming period from spring to fall and vigorous plant growth habit. In May 2008, line ‘K2008-107’ was vegetatively propagated, cultivated and evaluated. In August 2008, line ‘K2008-107’ was confirmed to be fixed and stable. Line ‘K2008-107’ was propagated and cultivated again in May 2009, May 2010 and May 2011 to reconfirm the stability of the line. Line ‘K2008-107’ was subsequently named ‘SAKPOR005’ and its unique characteristics were found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings.

SUMMARY

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

    • 1. Lemon yellow flower color;
    • 2. Flower blooming period from spring to fall; and
    • 3. Vigorous, semi-mounding and upright plant growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKPOR005’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on twelve-month-old plants grown under greenhouse conditions in Salinas, Calif. in the fall 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:

      • Botanical.—Portulaca oleracea.
      • Common.—Purslane.
      • Designation.—‘SAKPOR005’.
  • Parentage:
      • Female parent.—Proprietary Portulaca line ‘Mo04-19A-V2’ (unpatented).
      • Male parent.—Proprietary Portulaca line Ma01-3A-1B1’ (unpatented).
  • Growth:
      • Time to produce a rooted cutting.—About 2 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.
