Abstract

A new and distinct cultivar of Dahlia plant named ‘Karma Red Corona’, characterized by its upright and somewhat outwardly spreading plant habit; strong and erect peduncles; freely flowering habit; decorative-type inflorescence form; large inflorescences with bright red-colored ray florets; and good garden performance and postproduction longevity.

Description

Botanical designation: Dahlia hybrida.
Cultivar denomination: ‘Karma Red Corona’.
CROSS-REFERENCED TO RELATED APPLICATIONS
Dahlia Plant Named ‘Karma Pink Corona’; Aad W.M. Verwer, applicant; filed concurrently (U.S. Plant patent application Ser. No. 11/524,394).
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida, and hereinafter referred to by the name ‘Karma Red Corona’.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Lisse, The Netherlands. The objective of the breeding program is to create new cut flower Dahlia cultivars that have a freely flowering habit, decorative inflorescence form, attractive ray floret coloration, and good postproduction longevity.
The new Dahlia is a naturally-occurring branch mutation of the Dahlia hybrida cultivar Karma Corona, disclosed in U.S. Plant Pat. No. 13,650. The new Dahlia was discovered and selected by the Inventor from within a population of plants of the cultivar Karma Corona in a controlled environment in Lisse, The Netherlands during the summer of 2001.
Asexual reproduction of the new Dahlia by cuttings since the spring of 2002 in a controlled environment in Lisse, The Netherlands, has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Karma Red Corona 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 traits have been repeatedly observed and are determined to be the unique characteristics of ‘Karma Red Corona’. These characteristics in combination distinguish ‘Karma Red Corona’ as a new and distinct cultivar of Dahlia:
    • 1. Upright and somewhat outwardly spreading plant habit.
    • 2. Strong and erect peduncles.
    • 3. Freely flowering habit.
    • 4. Decorative-type inflorescence form.
    • 5. Large inflorescences with bright red-colored ray florets.
    • 6. Good garden performance and postproduction longevity.
Compared to plants of the parent, the cultivar Karma Corona, plants of the new Dahlia differ primarily in ray floret color as plants of the cultivar Karma Corona have golden orange-colored ray florets.
Compared to plants of the cultivar Karma Pink Corona, plants of the new Dahlia differ primarily in ray floret color as plants of the cultivar Karma Pink Corona have light purple-colored ray florets. In addition, plants of the new Dahlia are taller than plants of the cultivar Karma Pink Corona.
Plants of the new Dahlia can be compared to plants of the Dahlia cultivar Witteman's Best, not patented. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Witteman's Best in the following characteristics:
    • 1. Plants of the new Dahlia were shorter than plants of the cultivar Witteman's Best.
    • 2. Inflorescences of plants of the new Dahlia had longer postproduction longevity than plants of the cultivar Witteman's Best.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Dahlia. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia. The photograph comprises a side perspective view of typical flowering plants of ‘Karma Red Corona’ grown in an outdoor nursery.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Lisse, The Netherlands during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Dahlia production. During the production of the plants, day temperatures ranged from 15° C. to 30° C. and night temperatures ranged from 10° C. to 20° C. Plants were pinched one time about three to four weeks after planting. Measurements and numerical values represent averages for typical flowering plants. Plants were about four months old when the photograph and description were taken.
