BOTANICAL CLASSIFICATION/CULTIVAR DENOMINATION
Impatiens hawkeri cultivar Duepetwhite.
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 `Duepetwhite`.
The new Impatiens is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to develop New Guinea Impatiens cultivars that have a uniform plant habit and attractiveflower colors.
The new Impatiens originated from a cross made by the Inventor of a proprietary selection of Impatiens hawkeri identified as code number 94-104-1, not patented, as the female, or seed parent, with a proprietary selection of Impatiens hawkeriidentified as code number L-94-9, not patented, as the male, or pollen parent. The cultivar Duepetwhite was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Rheinberg,Germany.
Asexual reproduction of the new cultivar by terminal cuttings taken in Rheinberg, Germany, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Duepetwhite`. These characteristics in combination distinguish `Duepetwhite` as a new and distinct Impatiens cultivar:
1. Upright, rounded and uniform plant habit.
2. Freely branching and freely flowering habit.
3. White-colored flowers that are positioned above and beyond the leaves.
4. Dark green-colored leaves.
Plants of the new Impatiens can be compared to plants of the female parent, the selection 94-104-1. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Impatiens were more uniform in plant habit than plants of theselection 94-104-1.
Plants of the new Impatiens can be compared to plants of the male parent, the selection L-94-9. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Impatiens differed from plants of the selection L-94-9 in thefollowing characteristics:
1. Plants of the new Impatiens were more compact than plants of the selection L-94-9.
2. Plants of the new Impatiens had larger flowers than plants of the selection L-94-9.
Plants of the new Impatiens are similar to plants of the cultivar Moorea, disclosed in U.S. Plant Pat. No. 9,147, in flower color. However, in side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Impatiens differed fromplants of the cultivar Moorea in the following characteristics:
1. Plants of the new Impatiens were slightly shorter than plants of the cultivar Moorea.
2. Plants of the new Impatiens had smaller leaves than plants of the cultivar Moorea.
3. Plants of the new Impatiens were more freely flowering than plants of the cultivar Moorea.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightlyfrom 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 `Duepetwhite` grown in a container.
DETAILED BOTANICAL DESCRIPTION
The cultivar Duepetwhite 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 aforementioned photographs, following observations and measurements describe plants grown in Rheinberg, Germany, under commercial practice in a glass-covered greenhouse. Plants were about 16 weeks from cuttings and were grown in 12-cmcontainers. During the production of the plants, day and night temperatures averaged 18.degree. C. and light levels were about 4,500 lux.
