|||||||||||||||||
The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, known by the name `Kirawa`, and hereinafter referred to by the cultivar name `Tarawa`.
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 new varieties that have a uniform plant habit, attractive flower colors, good flower form and numerous flowers per plant.
The new cultivar originated from a cross made bythe inventor of a proprietary seedling selection identified as R556 as the male, or pollen parent, with the proprietary seedling selection identified as O419 as the female, or seed patent. The cultivar Tarawa was discovered and selected by the inventot as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany. 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 `Tarawa`. These characteristics in combination distinguish `Tarawa` as a new and distinct cultivar:
1. Flat and rounded red-colored flowers.
2. Freely flowering habit.
3. Outwardly spreading, rounded and mounding growth habit.
4. Dark green, slightly glossy, non-variegated foliage.
The new New Guinea Impatiens is similar in flower color to the New Guinea Impatiens cultivar `Lanai` (disclosed in U.S. Plant Pat. No. 8,397). However in side-by-side comparisons in Encinitas, Calif., under commercial practice, plants of the New Guinea Impatiens differed from plants of the cultivar `Lanai` in the following characteristics:
1. Plants of the new New Guinea Impatiens are more outwardly spreading and rounded than plants of the cultivar `Lanai`.
2. Plants of the new Guinea Impatiens have dark red stems whereas plants of the cultivar `Lanai` have green stems with red streaks.
3. Leaves of plants of the new Guinea Impatiens are not as glossy as leaves of plants of the cultivar `Lanai`.
4. Lower surfaces of mature leaves of plants of the new Guinea Impatiens are grayed red in color whereas lower surfaces of mature leaves of the cultivar `Lanai` are light green.
5. Plants of the new New Guinea Impatiens are more freely flowering than plants of the cultivar `Lanai`.
6. Flowers of plants of the new New Guinea Impatiens are larger, flatter and more rounded than flowers of plants of the cultivar `Lanai`.
7. Peduncles of plants of the new New Guinea Impatiens are longer than peduncles of plants of the cultivar `Lanai`.
A detailed comparison of plants of the new New Guinea Impatiens and the cultivar `Lanai` appears in Chart A at the end of the specification.
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 first photograph comprises a top perspective view of a typical plant of `Tarawa`.
The second photograph comprises a close-up view of typical flowers and upper (left) and lower (right) surfaces of leaves of the varieties `Lanai` (top) and `Tarawa` (bottom).
Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.
The cultivar `Tarawa` has not been observed under all possible environmental conditions. The phenotpe 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 plants grown 10-cm pots in Encinitas, Calif., under commercial practice in a fiberglass-covered greenhouse with day temperatures ranging from 23 to 29 C. and night temperatures ranging from 16 to 18 C. and light levels averaging 3,000 footcandles.
