|||||||||||||||||||||||||
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 cultivar name `Kijos`.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop early-flowering varieties with numerous flowers, uniform plant habit, attractive flower and foliage colors, and good flower form.
The new cultivar originated from a cross made by the Inventor of the cultivar `Moorea` (disclosed in U.S. Plant Pat. No. 9,147) as the male, or pollen parent, with the proprietary selection MF 302 as the female, or seed parent.
The cultivar `Kijos` was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany, in April, 1996.
Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Kijos`. These characteristics in combination distinguish `Kijos` as a new and distinct cultivar:
1. Numerous white-colored flowers that are held above the foliage.
2. Upright and outwardly spreading; broad "V"-shaped; uniform, rounded canopy.
3. Very freely branching, dense and bushy plant habit.
4. Dark green leaves.
Compared to plants of the female parent, the proprietary selection MF 302, plants of the new New Guinea Impatiens have larger flowers, larger leaves and more rounded flowers.
Plants of the new New Guinea Impatiens are similar in flower color to plants of the male parent, the cultivar `Moorea`. However, in side-by-side comparisons conducted in Encinitas, Calif., plants of the new New Guinea Impatiens differed from plants of the cultivar `Moorea` in the following characteristics:
1. Plants of the new New Guinea Impatiens are larger, more vigorous, have longer lateral branches, and are more spreading than plants of the cultivar `Moorea`.
2. Plants of the new New Guinea Impatiens are more freely branching than plants of the cultivar `Moorea`.
3. Leaves of plants of the new New Guinea Impatiens are longer and wider than leaves of plants of the cultivar `Moorea`.
4. Flowers of plants of the new New Guinea Impatiens are held higher above the canopy and are angled more outwardly than flowers of plants of the cultivar `Moorea`.
5. Flowers of plants of the new New Guinea Impatiens are slightly smaller and more rounded than flowers of plants of the cultivar `Moorea`.
6. Plants of the new New Guinea Impatiens flower about 7 to 10 days earlier than plants of the cultivar `Moorea`.
A detailed comparison of plants of the cultivars `Kijos` and `Moorea` appears in Chart A at the end of the specification.
Plants of the new New Guinea Impatiens are also similar in flower color to plants of the cultivar `Jasius`, disclosed in U.S. Plant Pat. No. 7,345. However, in side-by-side comparisons conducted in Gensingen, Germany, plants of the new New Guinea Impatiens were smaller; had broader, stiffer leaves; had more rounded flowers; and flowered about 10 to 14 days earlier than plants of the cultivar `Jasius`.
The accompanying colored photographs illustrate 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. The photograph at the top of the sheet comrpises a top perspective view of a typical plant of the cultivar `Kijos`. The photograph at the bottom of the sheet comrpises a comparison close-up view of typical flowers and leaves of the cultivars `Kijos` (left) and `Moorea` (right). Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.
Plants of the cultivar `Kijos` have 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 observations, measurements and comparisons describe three plants measured separately in 25-cm hanging baskets in Encinitas, Calif., under commercial practice in a polyethylene- covered greenhouse with day temperatures ranging from 21 to 32°C and night temperatures ranging from 16 to 18°C and light levels of about 3,500 footcandles.
