Description

Genus and species of the plant claimed: Dahlia (hybrid).

Variety denomination: ‘Bounty’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as a Dahlia (hybrid), and hereinafter referred to by the name ‘Bounty’. The new cultivar ‘Bounty’ is a product of a planned breeding program and was selected by the Inventor, Jan Skjold Knudsen, in Fyn, Denmark. The new cultivar ‘Bounty’ originated from a cross made by the Inventor between the Dahlia cultivar designated ‘Tonga’ (unpatented) as the female parent and the Dahlia cultivar designated ‘Malaysia’ (unpatented) as the male parent.

Asexual reproduction by cuttings of the new variety in Fyn, Denmark has demonstrated that the combination of characteristics as described herein for ‘Bounty’ are firmly fixed and are retained through successive generations of asexual reproduction. The new variety reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

‘Bounty’ has not been tested under all available environmental conditions and the phenotype may vary with variations in environmental conditions such as temperature, light intensity, day length and humidity, without a change in genotype of the plant.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bounty’. The following characteristics in combination distinguish ‘Bounty’ as a new and distinct cultivar:

    • 1. White ray floret color, RHS 155A;
    • 2. Compact plant habit; and
    • 3. Vigorous growth habit.

Side-by-side comparisons between the new Dahlia cultivar ‘Bounty’ and the parental cultivars, ‘Tonga’ and ‘Malaysia’, were conducted by the Inventor in Fyn, Denmark. ‘Bounty’ differs from the female parental cultivar, ‘Tonga’, primarily in ray floret color. ‘Bounty’ has white ray florets, RHS 155A, whereas the ray floret color of ‘Tonga’ is gray-red, RHS 181C to gray-yellow, RHS 161A. ‘Bounty’ differs from the male parental cultivar, ‘Malaysia’, primarily in ray floret color and inflorescence size. Bounty has white ray florets, RHS 155A, whereas the ray floret color of ‘Malaysia’ is red-purple, RHS 63B to 63C. ‘Bounty’ has an inflorescence diameter of 7-8 cm, whereas the inflorescence diameter of ‘Malaysia’ is 6.5 cm.

Of the commercial cultivars known to the Inventor, the most similar in comparison to ‘Bounty’ is the female parental cultivar ‘Tonga’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and details of inflorescence form color and structures of the new cultivar, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new Dahlia.

The first photograph is a side view of a typical flowering plant of ‘Bounty’ as grown in an 11 cm pot.

The second photograph is a top view of a typical flowering plant of ‘Bounty’.

The third photograph is a close-up of the inflorescence of ‘Bounty’.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe plants grown under commercial conditions. Plants described were 12 to 14 weeks old, and were grown in a greenhouse in Fyn, Denmark with average day temperatures of 18° C. to 25° C., and night temperature of 16° C. All color references are measured against The Royal Horticultural Society (R.H.S.) Colour Chart. Colors are approximate as color depends on horticultural practices such as light level and treatment rate, among others, without however any variance in genotype.
