| Abstract: |
A new and distinct cultivar of Dahlia plant named `Baldelmim`, characterized by its double type white-colored flowers, medium green-colored foliage, and moderately vigorous, upright-mounded growth habit. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of Dahlia plant named `Baldelmim`, substantially as herein shown and described. |
| Description: |
Latin name of genus and species of plant claimed: Dahlia variabilis.
Variety denomination: `Baldelmim`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Dahlia plant botanically known as Dahlia variabilis and hereinafter referred to by the cultivar name `Baldelmim`.
The new cultivar originated in a controlled breeding program in Rijsenhout, the Netherlands during July 1999. The objective of the breeding program was the development of Dahlia cultivars that are freely flowering with large flowers and amoderately vigorous growth habit.
The new Dahlia cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is the proprietary Dahlia variabilis breeding selection designated 3236, not patented, characterized by its double type white-coloredflowers, medium green-colored foliage, and semi-upright growth habit. The male (pollen) parent of the new cultivar is unknown. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above statedopen-pollination during September 2000 in a controlled environment at Rijsenhout, the Netherlands.
Asexual reproduction of the new cultivar by terminal stem cuttings since September 2000 at Rijsenhout, the Netherlands and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, asherein described, firmly fixed and retained through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish `Baldelmim` as a new and distinct cultivar of Dahlia plant: 1. Double type, white-colored flowers; 2. Medium green-colored foliage;and 3. Moderately vigorous, upright-mounded growth habit.
Plants of the new cultivar differ from plants of the female parent primarily in flower color and flower size. Plants of the new cultivar have milky white-colored flowers whereas plants of the female parent have plain white-colored flowers.
Of the many commercially available Dahlia cultivars, the most similar in comparison to the new cultivar is Delicious.TM. Marshmallow `Baldelmalo`, U.S. Plant Pat. No. 16,518. However, in side by side comparisons, plants of the new cultivardiffer from plants of `Baldelmalo` in the following characteristics: 1. Plants of the new cultivar are shorter than plants of `Baldelmalo`; 2. Plants of the new cultivar have fewer ray florets than plants of `Baldelmalo`; and 3. Plants of the newcultivar have longer peduncles than plants of `Baldelmalo`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly fromthe color values cited in the detailed description, which accurately describes the colors of `Baldelmim`. The plants were grown in 4.5 inch pots for 9 weeks in a greenhouse at West Chicago, Ill.
FIG. 1 illustrates a side view of the overall growth and flowering habit of `Baldelmim`.
FIG. 2 illustrates a close-up view of an individual inflorescence of `Baldelmim` with ray florets and disc florets fully opened.
DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and daylength, without, however, any variance in genotype.
The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color valueswere determined on Apr. 4, 2007 between 9:00 a.m. and 11:00 a.m. under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at WestChicago, Ill. in 4.5 inch pots for 9 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70.degree. F. to 77.degree. F. (21.degree. C. to 25.degree. C.) during the day and approximately 65.degree. F.to 68.degree. F. (18.degree. C. to 20.degree. C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Botanical classification: Dahlia variabilis cultivar Baldelmim.
