Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘DLFDANT3’, characterized by its upright plant habit; vigorous growth habit and rapid growth rate; dark green-colored leaves; uniform and freely flowering habit; strong upright flowering stems with numerous inflorescences; decorative-type inflorescences with ray florets that are initially purplish red in color becoming light purple with development; relative tolerance to low and high production temperatures; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DLFDANT3’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFDANT3’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum x morifolium ‘Delidante’, not patented. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within a population of plants of ‘Delidante’ in a controlled greenhouse environment in Maasdijk, The Netherlands in October, 2012.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since October, 2012 in a controlled greenhouse environment in Maasdijk, The Netherlands has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘DLFDANT3’. These characteristics in combination distinguish ‘DLFDANT3’ as a new and distinct Chrysanthemum plant:

- 1. Upright plant habit.
- 2. Vigorous growth habit and rapid growth rate.
- 3. Dark green-colored leaves.
- 4. Uniform and freely flowering habit.
- 5. Strong upright flowering stems with numerous inflorescences.
- 6. Decorative-type inflorescences with ray florets that are initially purplish red in color becoming light purple with development.
- 7. Relatively tolerant to low and high production temperatures.
- 8. Good postproduction longevity.

Plants of the new Chrysanthemum differ from plants of the mutation parent, ‘Delidante’, in ray floret color as plants of the new Chrysanthemum have darker purple-colored ray florets than plants of ‘Delidante’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Delibartica Pink’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Delibartica Pink’ in ray floret color as plants of the new Chrysanthemum are initially purplish red in color becoming light purple with development whereas ray florets of ‘Delibartica Pink’ are light pink in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘DLFDANT3’ grown as a spray-type cut flower.

The photograph on the second sheet is a close-up view of upper (top of the photographic sheet) and lower (bottom of the photographic sheet) surfaces of typical leaves (left) and inflorescences (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. 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 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 8 klux. Plants were grown as single-stem spray-type plants and were nine weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
