A new and distinct cultivar of Chrysanthemum plant named ‘DekDakar’, characterized by its anemone-type inflorescences with bright yellow-colored ray florets and darker yellow-colored disc florets; strong and upright flowering stems; freely flowering habit; early and uniform flowering response; and good postproduction longevity.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar DekDakar.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and referred to by the name ‘DekDakar’.

The new Chrysanthemum is the product of a planned breeding program conducted by the Inventor in Hensbroek, The Netherlands. The objective of the breeding program is to create new cut Chrysanthemum cultivars with interesting inflorescence forms and attractive floret coloration.

The new Chrysanthemum originated from a cross-pollination made by the Inventor on Jan. 28, 2001, in Hensbroek, The Netherlands, of a proprietary selection of Chrysanthemum identified as code number 5003,46, not patented, as the female, or seed, parent with a proprietary Chrysanthemum selection identified as code number 5003,61, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in Hensbroek, The Netherlands.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in Hensbroek, The Netherlands since October, 2001, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar DekDakar 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 ‘DekDakar’. These characteristics in combination distinguish ‘DekDakar’ as a new and distinct cultivar:

• • 1. Anemone-type inflorescences with bright yellow-colored ray florets and darker yellow-colored disc florets; typically grown as a spray type.
  • 2. Strong and upright flowering stems.
  • 3. Freely flowering habit.
  • 4. Early and uniform flowering response.
  • 5. Good postproduction longevity.

Compared to plants of the female parent selection, plants of the new Chrysanthemum have larger leaves, flower earlier and have larger inflorescences. In addition, plants of the new Chrysanthemum and the female parent selection differ in inflorescence form and ray floret coloration as plants of the female parent have daisy-type inflorescences with orange-colored ray florets.

Compared to plants of the male parent selection, plants of the new Chrysanthemum have lighter green-colored leaves and flower faster. In addition, plants of the new Chrysanthemum and the male parent selection differ in inflorescence form and ray floret coloration as plants of the male parent have daisy-type inflorescences and red-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Annecy Dark Yellow, disclosed in U.S. Plant Pat. No. 14,890. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Annecy Dark Yellow in the following characteristics:

• • 1. Plants of the new Chrysanthemum had smaller leaves than plants of the cultivar Annecy Dark Yellow.
  • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Annecy Dark Yellow.
  • 3. Plants of the new Chrysanthemum and the cultivar Annecy Dark Yellow differed in ray floret coloration.

Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Cappa Yellow. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Cappa Yellow in the following characteristics:

• • 1. Plants of the new Chrysanthemum were not as vigorous as plants of the cultivar Cappa Yellow.
  • 2. Plants of the new Chrysanthemum were more uniform than plants of the cultivar Cappa Yellow.
  • 3. Plants of the new Chrysanthemum flowered earlier than plants of the cultivar Cappa Yellow.

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 during the winter in Hensbroek, The Netherlands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 17.5 to 22° C., night temperatures were about 18.5° C. and light levels were about five kilolux. Plants were pinched once and were about twelve weeks from planting when the photographs and the description were taken.
