New Guinea Impatiens plant named ‘SAKIMP005’

Abstract

A New Guinea Impatiens cultivar particularly distinguished by having large, pinkish-red flowers, vigorous rooting, spreading growth habit and variegated leaves is disclosed.

Description

Genus and species: Impatiens×hybrida.

Variety denomination: ‘SAKIMP005’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of New Guinea Impatiens, botanically known as Impatiens×hybrida, and hereinafter referred to by the cultivar name ‘SAKIMP005’. ‘SAKIMP005’ originated from an interspecific hybridization between ‘NG-02WM1’, an unpatented proprietary deep-orange flowered Impatiens plant and ‘NG-01H-15B’, an unpatented proprietary magenta flowered Impatiens plant, in Misato, Japan.

In April 2002, the female parent line ‘NG-02WM1’ and male parent line ‘NG-01H-15B’ were crossed and a population of F₁ plants was created. The F₁ plants were evaluated in Misato, Japan in an open field trial. The criteria for plant selection included spreading growth habit, vigorous rooting, pinkish-red flower color and variegated leaves. At the completion of the trial, one single-plant selection was made based on the above criteria and vegetatively propagated. From May to August 2004, the selection was evaluated in an open field in Misato, Japan. The selection was also evaluated in an open field trial during the summer of 2004 in Athens, Ga., USA. Shoot-tip cuttings of the variety were then shipped in Salinas, Calif., where the plants were regenerated and reevaluated for stability of traits. The selection subsequently was named ‘SAKIMP005’ and found to have its unique characteristics reproduce true to type in successive generations of asexual propagation. The instant plant was asexual reproduced by vegetative cutting in Salinas, Calif.

Plant Breeder's Rights for this cultivar were applied for in Canada on Mar. 28, 2007.

SUMMARY OF THE INVENTION

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

• • 1. Pinkish-red flower color;
  • 2. Spreading growth habit;
  • 3. Vigorous rooting; and
  • 4. Variegated leaves.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘SAKIMP005’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The plant history was taken on plants grown for about four months from propagation by terminal cuttings under greenhouse conditions. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^th edition (2001). Anatomic labels are from The Cambridge Illustrated Glossy of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

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. Plants were fertilized every 2-3 days, 2 times in consecutive applications and then given one clear water application.
