Latest Yoder Brothers, Inc. Patents:
The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus rosa-sinensis, and hereinafter referred to by the cultivar name Light Wind.
The new cultivar is a product of a planned breeding program conducted by the inventor in Alva, Fla. The objective of the breeding program is to create new Hibiscus cultivars having uniform plant habit, early flowering, numerous flowers per lateral branch, desirable flower color, resistance to flower bud abscission, and good postproduction longevity.
The new cultivar originated from a cross made by the inventor in Alva, Fla. of the proprietary seedling selection identified as number 1184 as the female, or seed, parent with the commerical cultivar Waikiki (disclosed in U.S. Plant Pat. No. 7,834) as the male, or pollen parent. Compared to plants of the dark orange-colored proprietary seedling selection number 1184, plants of the new Hibiscus have a more uniform plant habit, more flowers and are more freely branching. Compared to plants of the cultivar Waikiki, plants of the new Hibiscus have more upright growth habit, darker foliage, smaller flowers, lighter flower color, and more uniform flowering. In addition, plants of the new Hibiscus have a white flower throat color whereas plants of the cultivar Waikiki have a dark red flower throat color.
The cultivar Light Wind was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., on Aug. 26, 1993. The selection of this plant was based on its desirable flower color, resistance to flower bud abscission, good postproduction longevity, and uniform plant habit and flowering.
The new Hibiscus is similar to plants of the nonpatented cultivar Pink Versicolor. In side-by-side comparisons conducted in Alva, Fla., plants of the new cultivar differ from plants of the cultivar Pink Versicolor in the following characteristics:
1. Plants of the new Hibiscus have smaller leaves than plants of the cultivar Pink Versicolor.
2. Plants of the new Hibiscus have more flowers than plants of the cultivar Pink Versicolor.
3. Plants of the new Hibiscus have lighter pink-colored flowers than plants of the cultivar Pink Versicolor.
4. Flower throat color of plants of the new Hibsicus is white whereas flower throat color of plants of the cultivar Pink Versicolor is dark red.
5. Plants of the new Hibiscus flower are more resistant to flower bud abscission than plants of the cultivar Pink Versicolor.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla., has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.
The cultivar Light Wind has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, nutrition and water status without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be unique characteristics of `Light Wind`. These characteristics in combination distinguish `Light Wind` as a new and distinct cultivar:
1. Very dark green leaves with long petioles.
2. Upright and compact, uniform and symmetrical plant habit.
3. Very freely branching.
4. Freely flowering, numerous light pink-colored flowers with white throat color.
5. Good resistance to flower bud abscission.
6. Excellent postproduction longevity.
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 side perspective view of typical plant of `Light Wind`. The second photograph comprises a close-up view of a typical flower of `Light Wind`. Flower and foliage colors in the photographs may appear different from the actual colors due to the light reflectance.
The aformentioned and following observations, measurements, values, and comparisons describe plants grown in Alva, Fla., in 15-cm containers with day temperatures ranging from 16.degree. to 35.degree. C. and night temperatures ranging from 10.degree. to 24.degree. C. Plants were grown under a polypropylene covering with light levels ranging from 6,000 to 9,000 footcandles.
In the following descriptions, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
