Abstract

A new and distinct cultivar of New Guinea Impatiens plant named `Kijuan`, characterized by its small and numerous blush pink-colored flowers; compact, upright and outwardly spreading growth habit; freely branching plant habit; and narrow dark green slightly glossy non-variegated leaves.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, previously known under the code name, MF 338 Blush, and hereinafter referred to by the cultivar name `Kijuan`.
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 compact varieties with numerous small flowers, early-flowering, 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 proprietary selection identified as MF 571 as the male, or pollen parent, with the proprietary selection identified as MF 22 as the female, or seed parent. The cultivar `Kijuan` 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.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Kijuan`. These characteristics in combination distinguish `Kijuan` as a new and distinct cultivar:
1. Small and numerous blush pink-colored flowers.
2. Compact, upright and outwardly spreading growth habit.
3. Freely branching plant habit.
4. Narrow dark green, slightly glossy non-variegated leaves.
Plants of the new New Guinea Impatiens have darker green foliage and lighter flower color than plants of the male parent, MF 571. Compared to plants of the female parent, MF 22, plants of the new New Guinea Impatiens are larger and have darker pink and more rounded flowers.
Plants of the new New Guinea Impatiens are similar in flower color to the New Guinea Impatiens cultivar `Apple Blossom` (disclosed in U.S. Plant Pat. No. 10,111). However in side-by-side comparisons in Encinitas, Calif., under commercial practice, plants of the new New Guinea Impatiens differed from plants of the cultivar `Apple Blossom` in the following characteristics:
1. Plants of the new New Guinea Impatiens are more compact than plants of the cultivar `Apple Blossom`.
2. Leaves of plants of the new New Guinea Impatiens are darker green and more narrow than leaves of plants of the cultivar `Apple Blossom`.
3. Leaf petioles of plants of the new New Guinea Impatiens are shorter than leaf petioles of plants of the cultivar `Apple Blossom`.
4. Flowers of plants of the new New Guinea Impatiens are held above the foliage whereas flowers of plants of the cultivar `Apple Blossom` are held at canopy level or slightly below.
5. Flowers of plants of the new New Guinea Impatiens are smaller and have a less distinct "eye" at the center of the flower than flowers of plants of the cultivar `Apple Blossom`.
6. Flower peduncles of plants of the new New Guinea Impatiens are longer than flower peduncles of plants of the cultivar `Apple Blossom`.
A detailed comparison of plants of the new New Guinea Impatiens and the cultivar `Apple Blossom` appears in Chart A at the end of the specification.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 comprises a side perspective view of a typical plant of `Kijuan`.
The photograph at the bottom of the sheet comprises a close-up view of a typical flower and leaves of `Kijuan`. Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
The cultivar `Kijuan` 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 observations, measurements and comparisons describe plants grown in 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 of about 3,000 footcandles.
