Abstract
A distinct cultivar of Dahlia plant named `Dapaor`, characterized by its fully double dark orange inflorescences; uniform growth habit; dark green foliage; and strong peduncles that hold inflorescences above the foliage.
Description
The present invention relates to a new and distinct variety of Dahlia plant, botanically known as Dahlia variabilis, and hereinafter referred to by the name `Dapaor`.
The new Dahlia is a naturally-occurring whole plant mutation of the yellow-flowered Dahlia variabilis `Margaret`, disclosed in U.S. Plant Pat. No. 6,769. The new Dahlia was discovered by the Inventor in a controlled environment in Enkhuizen, The Netherlands, within a population of plants of `Margaret`. The selection of this plant was based on its orange double flowers and compact plant habit in 1993.
Asexual reproduction of the new Dahlia by terminal cuttings harvested in Enkhuizen, The Netherlands, has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
The new Dahlia 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 `Dapaor`. These characteristics in combination distinguish `Dapaor` as a new and distinct cultivar:
1. Fully double dark orange inflorescences.
2. Dark green foliage.
3. Strong peduncles that hold inflorescences above the foliage.
The new Dahlia can be compared to the Dahlia cultivar `Simon`, disclosed in U.S. Plant Pat. No. 6,770. However in side-by-side comparisons conducted in West Chicago, Ill., plants of the new Dahlia differ from plants of the cultivar `Simon` in the following characteristics:
1. Plants of the new Dahlia are broader and more freely branching than plants of the cultivar `Simon`.
2. Plants of the new Dahlia have green-colored stems and petioles whereas plants of the cultivar `Simon` have dark red purple-colored stems and petioles.
3. Plants of the new Dahlia have larger leaves than plants of the cultivar `Simon`.
4. Plants of the new Dahlia are more floriferous although they have fewer ray and disc florets per inflorescence than plants of the cultivar `Simon`.
5. Ray florets of plants of the new Dahlia are darker orange than ray florets of plants of the cultivar `Simon`.
6. Plants of the new Dahlia have shorter peduncles than plants of the cultivar `Simon`.
The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type. The photograph comprises a side perspective view of a typical plant of the new Dahlia. Ray floret and foliage colors may appear different from the actual colors due to light reflectance.
The following observations and measurements describe plants grown in West Chicago, Ill., in 10-cm containers in a glass greenhouse with average day temperatures about 20 to 22° C., average night temperatures about 18 to 20° C., and light levels about 2,500 to 3,000 foot-candles. Plants were planted about 4 weeks after propagating unrooted cuttings and were pinched about three weeks after planting. Plants were in full flower and descriptions were taken about 8 weeks after planting.
In the following description, color references are made to The Royal Horitcultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
Botanical classification: Dahlia variabilit `Dapaor`.
Parentage: Naturally-occurring whole plant mutation of Dahlia variabilis `Margaret`, disclosed in U.S. Plant Pat. No. 6,769.
Propagation:

Time to initiate roots.--About 4 days with temperatures of 22° C.
Time to develop roots.--About 14 days with temperatures of 22° C.
Rooting habit.--Terminal cuttings propagate easily, roots fibrous, thick and well-branched.
Tubers.--Plants of the new Dahlia will form tubers under short day conditions, that is at least 13 to 14 hours of darkness.
Plant description:

Stem description.--Quantity: About four to six per plant. Basally branching, however, plants typically require pinching to enhance lateral branch development. Lateral branch length: About 14.5 cm. Lateral branch diameter: About 6.1 mm. Internode length: About 2.25 cm. Texture: Smooth. Color: 144A.
Foliage description.--Arrangement: Young foliage, leaves single; fully expanded foliage, leaves simple, occasionally compound and trifoliate; opposite. Quantity of leaves per lateral branch: About 14. Leaflet length: About 11.25 cm. Leaflet width: About 5.75 cm. Leaflet shape: Ovate. Leaflet apex: Acuminate. Leaflet base: Attenuate. Leaflet margin: Serrate to dentate with fine ciliation. Leaflet texture: Slightly rugose. Petiole length: About 2.25 cm. Petiole diameter: About 3 mm. Color: Fully expanded foliage, upper surface: 139A. Fully expanded foliage, lower surface: 191A. Venation, both surfaces: 144C. Petiole: 144C.
Flowering description:
Appearance.--Fully double inflorescence form. Inflorescences generally hemispherical and borne on terminals above foliage, arising from leaf axils on strong peduncles; inflorescences face upright and/or outward. Typically about one or two inflorescence per lateral stem; about 8 to 18 inflorescences and buds per plant. Disc and ray florets arranged acropetally on a capitulum. Persistent. Not fragrant.
Flowering response.--Under natural conditions, plants flower intermittently from July to October in the Northern Hemisphere.
Flower longevity.--Flowers last about one to two weeks on the plant dependent on temperature.
Flower bud (just before opening).--Shape: Spherical. Length: About 1.75 cm. Diameter: About 1.75 cm. Color: Light green.
Inflorescence size.--Diameter: About 8 cm. Depth (height): About 1.25 cm. Disc diameter: About 1.5 cm.
Ray florets.--Quantity per inflorescence: About 60. Shape: Elongated, cupped. Length: About 3.1 cm. Width: About 2.25 cm. Apex: Pointed to slightly rounded. Base: Attenuate. Margin: Entire. Texture: Velvety. Color: Fully opened, upper surface: 33A; fading to 168C at apex. Fully opened, lower surface: 167B.
Disc florets.--Elongated, cylindrical; shiny. Quantity: About 35 per inflorescence. Length: About 1.35 cm. Diameter: About 2.5 mm. Color, mature: 12A.
Peduncle.--Aspect: Erect and strong. Length: About 9 cm. Texture: Smooth. Color: 183C.
Involucral bracts.--Quantity: About 5. Diameter of bract whorl: About 3 cm. Shape: Diamond-shaped. Tip: Rounded. Margin: Entire. Texture: Smooth, shiny. Color, upper and lower surfaces: 137B.
