Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DUEPETPASAL’.

BACKGROUND OF THE INVENTION

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

The new New Guinea Impatiens is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact New Guinea Impatiens cultivars with large and attractive flowers.

The new New Guinea Impatiens originated from a cross-pollination made by the Inventor in May, 2003 in Rheinberg, Germany of a proprietary selection of Impatiens hawkeri identified as code number F-16-07, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number F-14-09, not patented, as the male, or pollen, parent. The new New Guinea Impatiens was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2005.

Asexual reproduction of the new New Guinea Impatiens by terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since May, 2005, has shown that the unique features of this new New Guinea Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new New Guinea Impatiens have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Duepetpasal’. These characteristics in combination distinguish ‘Duepetpasal’ as a new and distinct cultivar of Impatiens:

• • 1. Compact, upright and outwardly spreading growth habit; mounded plant habit.
  • 2. Freely branching habit.
  • 3. Moderately vigorous growth habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Large salmon pink-colored flowers.
  • 7. Good garden performance.

Plants of the new New Guinea Impatiens can be compared to plants of the female parent selection. Plants of the new New Guinea Impatiens differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new New Guinea Impatiens are more compact than plants of the female parent selection.
  • 2. Plants of the new New Guinea Impatiens are more freely branching than plants of the female parent selection.

Plants of the new New Guinea Impatiens can be compared to plants of the male parent selection. Plants of the new New Guinea Impatiens differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new New Guinea Impatiens are more compact than plants of the male parent selection.
  • 2. Plants of the new New Guinea Impatiens are more freely branching than plants of the male parent selection.

Plants of the new New Guinea Impatiens can be compared to plants of Impatiens hawkeri ‘Fisimp 149’,disclosed in U.S. Plant Pat. No. 13,711. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new New Guinea Impatiens differed from plants of ‘Fisimp 149’ in the following characteristics:

• • 1. Plants of the new New Guinea Impatiens were more compact and had shorter internodes than plants of ‘Fisimp 149’.
  • 2. Plants of the new New Guinea Impatiens were more freely flowering than plants of ‘Fisimp 149’.
  • 3. Plants of the new New Guinea Impatiens had smaller leaves than plants of ‘Fisimp 149’.
  • 4. Plants of the new New Guinea Impatiens had smaller flowers than plants of ‘Fisimp 149’.
  • 5. Plants of the new New Guinea Impatiens had shorter peduncles than plants of ‘Fisimp 149’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Impatiens, showing 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 New Guinea Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘Duepetpasal’ grown in a container.
