Abstract

A new and distinct cultivar of New Guinea Impatiens plant named `Electra Hot White`, characterized by its large pure white flowers; flowers held above the foliage; rounded flower form; numerous flowers per plant; freely branching, dense and bushy plant habit; moderately vigorous and compact, rounded plant habit; dark green and glossy foliage that is flat and horizontal to the plant.

Description

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 `Electra Hot White`.
The new cultivar is a product of a planned breeding program conducted by the inventors in Coquille, Oreg. The objective of the breeding program was to develop varieties with uniform plant habit, attractive flower colors, good flower form, and numerous flowers per plant.
The new cultivar originated from a cross made in November, 1993, by the inventors of two unnamed proprietary seedling selections.
The cultivar `Electra Hot White` was discovered and selected by the inventors as a flowering plant within the progeny of the stated cross in a controlled environment in Coquille, Oreg. Asexual reproduction of the new cultivar by terminal cuttings taken at Coquille, Oreg., has shown that the unique features of this new New Guinea 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 unique characteristics of `Electra Hot White`. These characteristics in combination distinguish the new New Guinea Impatiens as a new and distinct cultivar:
1. Large pure white flowers.
2. Flowers held above the foliage.
3. Rounded flower form.
4. Numerous flowers per plant.
5. Freely branching, dense and bushy plant habit.
6. Moderately vigorous and compact, rounded plant habit.
7. Dark green and glossy foliage that is flat and horizontal.
In contrast to plants of the new New Guinea Impatiens, plants of the parent proprietary seedling selections have lighter green foliage, more upright habit, and smaller flowers.
The new New Guinea Impatiens is similar in flower color to the New Guinea Impatiens cultivar BSR-203 Pure White (disclosed in U.S. Plant Pat. No. 8,410). However, in side-by-side comparisons in Coquille, Oreg., under commercial practice, plants of the new New Guinea Impatiens differed from plants of the cultivar BSR-203 Pure White in the following characteristics:
1. Leaves of plants of the new New Guinea Impatiens are darker green than leaves of plants of the cultivar BSR-203 Pure White.
2. Stems of plants of the new New Guinea Impatiens are green whereas stems of plants of the cultivar BSR-203 Pure White have a brownish tinge.
3. Plants of the new New Guinea Impatiens flower earlier than flowers of plants of the cultivar BSR-203 Pure White.
4. Flowers of plants of the new New Guinea Impatiens are displayed higher above the foliage than flowers of plants of the cultivar BSR-203 Pure White.
5. Flowers of plants of the new New Guinea Impatiens are larger and more rounded than flowers of plants of the cultivar BSR-203 Pure White.
The new New Guinea Impatiens is also similar in flower color to the New Guinea Impatiens cultivar Moorea (disclosed in U.S. Plant Pat. No. 9,147). However in side-by-side comparisons in Coquille, Oreg., under commercial practice, 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 rounded in plant shape whereas plants of the cultivar Moorea are more upright.
2. Leaves of plants of the new New Guinea Impatiens are horizontal to the plant whereas leaves of plants of the cultivar Moorea are orientated upwards.
3. Leaves of plants of the new New Guinea Impatiens are longer than leaves of plants of the cultivar Moorea.
4. Plants of the new New Guinea Impatiens flower about one week earlier than flowers of plants of the cultivar Moorea.
5. Plants of the new New Guinea Impatiens have more flowers per lateral stem than of plants of the cultivar Moorea.
6. Flowers of plants of the new New Guinea Impatiens are displayed above the foliage whereas flowers of plants of the cultiar Moorea are often down in the foliage due to the longer peduncles on plants of the new New Guinea Impatiens.
7. Flowers of plants of the new New Guinea Impatiens are flat whereas flowers of plants of the cultiar Moorea are slightly cupped.
A detailed comparison of plants of the new New Guinea Impatiens and the cultivar Moorea appears in Chart A at the end of the specification.
The new New Guinea Impatiens has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.
The accompanying colored photographs illustrate the overall appearance and flower color of the new New Guinea Impatiens, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The first photograph comprises a side perspective view of a typical plant of the new New Guinea Impatiens.
The second photograph comprises a side perspective view of typical plants of the cultivar Moorea (left) and the new New Guinea Impatiens (right) showing the differences in plant and flowering habit. Flower and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
The following observations, measurements, values, and comparisons describe plants grown in Coquille, Oreg., grown under double layer of polyethylene with day temperatures ranging from 23 to 30C and night temperatures ranging from 10 to 18C, and light levels ranging from 3,000 to 5,000 footcandles.
