Abstract
A distinct cultivar of Dahlia plant named ‘Select White’, characterized by its upright and compact plant habit; freely branching, full and dense plants; medium-sized semi-double type inflorescences; white-colored ray florets with bright yellow-colored disc florets; and good garden performance.
Description
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia variabilis, commercially referred to as a pot-type Dahlia, and hereinafter referred to by the cultivar name ‘Select White’.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Mariahout-Laarbeek, The Netherlands. The objective of the breeding program is to create new pot-type Dahlia cultivars with desirable inflorescence form, attractive colors, and good garden performance.
The new Dahlia originated from a cross made by the Inventor of two unidentified proprietary Dahlia variabilis selections, not patented. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Mariahout-Laarbeek, The Netherlands. Plants of the new Dahlia differ from plants of the parent selections primarily in ray floret coloration.
Asexual reproduction of the new Dahlia by vegetative tip cuttings was first conducted in Mariahout-Laarbeek, The Netherlands in 1997. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
The cultivar ‘Selet White’ 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 ‘Select White’. These characteristics in combination distinguish ‘Select White’ as a new and distinct pot-type Dahlia:
1. Upright and compact plant habit.
2. Freely branching, full and dense plants.
3. Medium-sized semi-double type inflorescences.
4. White-colored ray florets with bright yellow-colored disc florets.
5. Good garden performance.
Plants of the new Dahlia can be compared to plants of the Dahlia cultivar ‘Mipawhi’, diclosed in U.S. Plant patent application Ser. No. 09/221,685 (abandoned). In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Dahlia had larger inflorescences, were more freely-flowering, flowered earlier, and had better garden performance than plants of the cultivar ‘Mipawhi’.
The accompanying colored photograph illustrates the overall appearance of the new Dahlia showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ 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 a typical flowering plant of ‘Select White’.
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. The following obervations and measurements describe plants grown and flowered during the spring in Venhuizen, The Netherlands, in a glass-covered greenhouse and with conditions which approximate those generally used in commercial production. One rooted cutting was planted in a 10-cm container and pinched about one week after planting. During the production time, the following environmental conditions were maintained: day temperatures, about 18 to 21° C.; night temperatures, about 15 to 18° C.; and light levels about 40,000 lux. Measurements and numerical values represent averages of typical flowering plants about 6 to 8 weeks after planting.
