Abstract

A distinct cultivar of Dahlia plant named ‘Kiedahsuy’, characterized by its upright, compact and rounded plant habit; freely basal branching habit; semi-double type inflorescences; and bright yellow-colored ray and disc florets.

Description

Botanical classification/cultivar designation: Dahlia variabilis cultivar Kiedahsuy.
BACKGROUND OF THE INVENTION
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 Kiedahsuy.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Venhuizen, The Netherlands. The objective of the breeding program is to create new pot-type Dahlia, cultivars with desirable inflorescence form and attractive ray and disc floret coloration.
The new Dahlia originated from a cross-pollination made by the Inventor in 1999 of a proprietary Dahlia variabilis selection identified as code number 98.1833, not patented, as the female, or seed, parent with a proprietary Dahlia variabills selection identified as code number 98.3426, not patented, as the male, or pollen, parent. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Venhuizen, The Netherlands.
Asexual reproduction of the new Dahlia by vegetative tip cuttings was first conducted in Mariahout-Laarbeek, The Netherlands since 2000. Asexual reproduction by cuttings 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 Kiedahsuy has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and daylength, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kiedahsuy’. These characteristics in combination distinguish ‘Kiedahsuy’ as a new and distinct pot-type Dahlia:
    • 1. Upright, compact and rounded plant habit.
    • 2. Freely basal branching habit, full and dense plants.
    • 3. Semi-double type inflorescences.
    • 4. Bright yellow-colored ray and disc florets.
    • 5. Good garden performance.
Compared to plants of the female parent, plants of the new Dahlia differ in ray floret coloration as plants of the female parent have pale yellow-colored ray florets. Compared to plants of the male parent plants of the new Dahlia differ primarily in ray floret coloration.
Plants of the new Dahlia can be compared to plants of the Dahlia cultivar Dahlstar Yellow, not patented. In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Dahlia are more compact, more freely branched, flower earlier and have more ray florets per inflorescence than plants of the cultivar Dahlstar Yellow.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Kiedahsuy’.
The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Kiedahsuy’.
 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 aforementioned photographs and following observations and measurements describe plants grown and flowered during the winter and early spring in Lompoc, Calif., under commercial practice in a polycarbonate-covered greenhouse with day temperatures about 18 to 24° C., night temperatures about 16 to 18° C., and light levels about 4,000 to 8,000 foot-candles. Rooted cuttings were planted in 10-cm container and plants had been growing for about ten weeks when the photographs and the description were taken.
