Abstract

A distinct cultivar of Kalanchoe plant named `Rocket`, characterized by its bright deep crimson flower color; upright plant habit; relative compactness; freely branching habit with shoots forming at every node; uniform plant habit and inflorescence display; small dark green glossy leaves; proportional leaf size to plant size; numerous flowers per plant; medium to large flowers; resistance to Botrytis, Rhizoctonia and Fusarium; and excellent postproduction longevity.

Description

The present invention relates to a new and distinct cultivar of Kalanchoe plant, botanically known as Kalanchoe blossfeldiana Adans., and hereinafter referred to by the cultivar name `Rocket`.
The new cultivar is a product of a planned breeding program conducted by the inventor in Soquel and Half Moon Bay, Calif. The objective of the breeding program was to create new Kalanchoe cultivars having a uniform and compact plant habit; freely branching habit; attractive flower and foliage colors; short response time; resistance to deseases and insects; and good postproduction longevity.
The new cultivar originated from a self-pollination made by the inventor of a proprietary Kalanchoe blossfeldiana Adans. selection code number 967-001. The cultivar `Rocket` was discovered and selected by the inventor in July, 1993, as a flowering plant within the progeny of the stated selfing in a controlled environment in Soquel, Calif. Compared to the parent selection, plants of the new Kalanchoe are larger, flower one week later, have larger leaves and have a different flower color.
Asexual reproduction of the new cultivar by terminal and node cuttings taken at Soquel and Half Moon Bay, Calif., has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.
The cultivar Rocket has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Rocket`. These characteristics in combination distinguish `Rocket` as a new and distinct cultivar:
1. Bright deep crimson flower color.
2. Upright plant habit, relatively compact.
3. Full plants, freely branching habit with shoots forming at every node. Plants do not require pinching.
4. Uniform plant habit and inflorescence display.
5. Small dark green glossy leaves.
6. Proportional leaf size to plant size.
7. Numerous flowers per plant.
8. Medium to large flowers.
9. Resistant to Botrytis, Rhizoctonia and Fusarium.
10. Not attractive to aphids.
11. Excellent postproduction longevity.
The new Kalanchoe is most similar in flower color to the commercial cultivar, Juliana (disclosed in U.S. Plant Pat. No. 02010,228).
However, in side-by-side comparisons in Soquel and Half Moon Bay, Calif., plants of the new Kalanchoe were more freely branching; more compact; and had smaller leaves than plants of the cultivar Juliana. Although flower color of plants of the cultivar Juliana is similar to flower color of plants of the new Kalanchoe, there is a discernible difference in the shade of the color. In addition, under high light, foliage of plants of the cultivar Juliana will become red, whereas under high light, foliage of plants of the new Kalanchoes will maintain remain dark green without reddening.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 comprises a top perspective view of a typical potted plant of `Rocket` taken in Soquel, Calif. Flower color in the photograph may appear different from the actual color due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Measurements and numerical values represent typical plants in 10.5-cm containers that were grown during the spring in Northern California. Plants were grown under cultural and environmental conditions that approximated commercial practice in a plastic-covered greenhouse with day temperatures ranging from 16 to 38° C. and night temperatures ranging from 4.5 to 13° C. Plants were exposed to five weeks of long day/short nights followed by six weeks of short day/long night photoperiodic treatments.
