Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘DLFZON1’, characterized by its strong and upright flowering stems; vigorous growth habit; dark green-colored leaves; relatively short response time; pompon inflorescences with white-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: ‘DLFZON1’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium, commercially grown as a cut flower and hereinafter referred to by the name ‘DLFZON1’.
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 freely-flowering cut Chrysanthemum plants with pompon inflorescences, strong flowering stems and excellent postproduction longevity.
The new Chrysanthemum plant originated from a cross-pollination made by the Inventor in Maasdijk, The Netherlands in March, 2013, of a proprietary selection of Chrysanthemum X morifolium identified as code designation DB 44792, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum X morifolium identified as code designation DB 43726, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in September, 2013.
Asexual reproduction of the new Chrysanthemum plant by terminal vegetative cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since September, 2013 has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.
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 ‘DLFZON1’. These characteristics in combination distinguish ‘DLFZON1’ as a new and distinct Chrysanthemum plant:
    • 1. Strong and upright flowering stems.
    • 2. Vigorous growth habit.
    • 3. Dark green-colored leaves.
    • 4. Relatively short response time.
    • 5. Pompon inflorescences with white-colored ray florets.
    • 6. Good postproduction longevity; plants maintain good substance for about two weeks in an interior environment.
Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Chrysanthemum and the female parent selection differ in ray floret color as plants of the female parent selection have yellow-colored ray florets.
    • 2. Plants of the new Chrysanthemum are not as resistant to Chrysanthemum White Rust as plants of the female parent selection.
Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Chrysanthemum and the male parent selection differ in ray floret color as plants of the male parent selection have light purple-colored ray florets.
    • 2. Plants of the new Chrysanthemum are not as resistant to Chrysanthemum White Rust (Puccinia horiana) as plants of the male parent selection.
Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘DLFHAL11’, not patented. In side-by-side comparisons plants of the new Chrysanthemum differ from plants of ‘DLFHAL11’ in the following characteristics:
    • 1. Plants of the new Chrysanthemum have smaller inflorescences and shorter ray florets than plants of ‘DLFHAL11’.
    • 2. Plants of the new Chrysanthemum are not as resistant to Chrysanthemum White Rust as plants of ‘DLFHAL11’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored 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. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘DLFZON1’ grown as a disbud-type.
The photograph on the second sheet comprises close-up views of the lower (top of the photographic sheet) and upper surfaces (bottom of the photographic sheet) of typical inflorescences and leaves of ‘DLFZON1’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the winter 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 22° C., night temperatures ranged from 19° C. to 21° C. and light levels averaged 8 klux. Plants 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.
