Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘KIE186’, characterized by its upright, outwardly spreading and mounded plant habit; freely branching habit; dense and bushy growth habit; dark green and yellow green variegated leaves; freely flowering habit; and large light pink-colored flowers that are positioned above and beyond the foliage.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘KIE186’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the name ‘KIE186’.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop new Impatiens cultivars with numerous large flowers and attractive foliage and flower coloration.

The new Impatiens originated from a cross-pollination made by the Inventor in November, 2000, of a proprietary selection of Impatiens hawkeri identified as code number 00-113, not patented, as the female, or seed, parent with the Impatiens hawkeri cultivar Kidomia, disclosed in U.S. Plant Pat. No. 14,143, as the male, or pollen, parent. The cultivar KIE186 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany in April, 2001.

Asexual reproduction of the new cultivar by terminal cuttings propagated in a controlled environment in Gensingen, Germany since May, 2001 has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar KIE186 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KIE186’. These characteristics in combination distinguish ‘KIE186’ as a new and distinct cultivar of New Guinea Impatiens:

• • 1. Compact, upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching habit; dense and bushy growth habit.
  • 3. Green and yellow green variegated leaves.
  • 4. Freely flowering habit.
  • 5. Large light pink-colored flowers that are positioned above and beyond the foliage.

In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Impatiens differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Impatiens had darker green-colored leaves than plants of the female parent selection.
  • 2. Plants of the new Impatiens had larger flowers than plants of the female parent selection.

In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Impatiens differed from plants of the male parent, the cultivar Kidomia, in the following characteristics:

• • 1. Leaf variegation of plants of the new Impatiens was less pronounced than leaf variegation of plants of the cultivar Kidomia.
  • 2. Plants of the new Impatiens had larger flowers than plants of the cultivar Kidomia.
  • 3. Plants of the new Impatiens and the cultivar Kidomia differed in flower coloration.

Plants of the new Impatiens can be compared to plants of the New Guinea Impatiens cultivar Balcelbupi, disclosed in U.S. Plant Pat. No. 13,410. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Impatiens differed from plants of the cultivar Balcelbupi in the following characteristics:

• • 1. Plants of the new Impatiens and the cultivar Balcelbupi differed in foliage color as plants of the cultivar Balcelbupi had dark green-colored foliage.
  • 2. Plants of the new Impatiens and the cultivar Balcelbupi differed slightly in flower color.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Encinitas, Calif. during the winter and early spring in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial New Guinea Impatiens production. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 19° C. and light levels averaged 4,000 foot candles. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in one-gallon containers and were about 18 weeks old when the photographs and the detailed description were taken.
