New Guinea Impatiens plant named ‘Odycorinth’

Abstract

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

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘Odycorinth’.

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 ‘Odycorinth’.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program was to develop new drought-tolerant New Guinea 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 May, 2002, of a proprietary selection of Impatiens hawkeri identified as code number 200104-03, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number 200025, not patented, as the male, or pollen, parent. The cultivar Odycorinth was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in De Kwakel, The Netherlands in July, 2003.

Asexual reproduction of the new cultivar by terminal cuttings propagated in a controlled environment in De Kwakel, The Netherlands since October, 2003 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 Odycorinth 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 ‘Odycorinth’. These characteristics in combination distinguish ‘Odycorinth’ as a new and distinct cultivar of New Guinea Impatiens:

• • 1. Upright, outwardly spreading and mounded plant habit.
  • 2. Vigorous and freely branching habit; dense and bushy growth habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large bright orange-colored flowers that are positioned above and beyond the foliage.

In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Impatiens differed from plants of the female parent selection primarily in flower color as plants of the female parent selection had duller orange-colored flowers. In addition, plants of the new Impatiens and the female parent selection differ in leaf shape.

In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Impatiens differed from plants of the male parent selection primarily in flower color as plants of the male parent selection had orange-colored flowers. In addition, plants of the new Impatiens and the male parent selection differ in leaf shape.

Plants of the new Impatiens can be compared to plants of the New Guinea Impatiens cultivar Timor, disclosed in U.S. Plant Pat. No. 9,144. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Impatiens differed from plants of the cultivar Timor in the following characteristics:

• • 1. Plants of the new Impatiens were more freely branching than plants of the cultivar Timor.
  • 2. Plants of the new Impatiens had slightly larger leaves than plants of the cultivar Timor.
  • 3. Plants of the new Impatiens and the cultivar Timor differed in flower color as plants of the cultivar Timor had darker orange-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Impatiens. The photograph show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘Odycorinth’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in De Kwakel, The Netherlands during the autumn in a glass-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 and night temperatures averaged 18° C. and light levels averaged 220 Watts per square meter. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 13-cm pots and were about three months old when the photograph and the detailed description were taken.
