New Guinea impatiens plant named ‘SAKIMP011’

Abstract

A New Guinea Impatiens cultivar particularly distinguished by having red flowers, a strong root system, and a compact growth habit, is disclosed.

Description

Genus and species: Impatiens×hybrida (hort).

Variety denomination: ‘SAKIMP011’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of New Guinea Impatiens, botanically known as Impatiens×hybrida (hort), and hereinafter referred to by the cultivar name ‘SAKIMP011’. ‘SAKIMP011’ originated from an interspecific hybridization between the female parent, ‘NG-02SM-13’, an unpatented proprietary orange-flowered Impatiens breeding line and the male parent, ‘NB-42ZA’, an unpatented proprietary lilac-flowered Impatiens breeding line in Misato, Japan.

In April 2002, the female parent line, ‘NG-02SM-13’ and the male parent line, ‘NB-42ZA’ 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 bright red flower color, strong root system and a compact growth habit. At the completion of the trial, one single-plant selection was made based on the above criteria and vegetatively propagated. From May to August 2005, the selection was evaluated in an open field in Masato, Japan. Shoot-tip cuttings of the variety were then shipped to Salinas, Calif., where the plants were regenerated and reevaluated for stability of traits. The selection subsequently was named ‘SAKIMP011’ and found to have its unique characteristics reproduce true to type in successive generations of asexual propagation.

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. Red flowers;
  • 2. A compact growth habit; and
  • 3. A strong root system.

DESCRIPTION OF THE PHOTOGRAPHS

This new impatiens plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are 5 months from their transplanting date and 6 months from the stick date.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘SAKIMP011’. The data which define these characteristics were collected from asexual reproductions carried out under greenhouse conditions in Salinas, Calif. The plant history was taken on plants grown for about five 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 Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.
