Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘DLFBLAN1’, characterized by its upright plant habit; vigorous growth habit; dark green-colored leaves; uniform and freely flowering habit; strong upright flowering stems with numerous inflorescences; anemone-type inflorescences with white-colored ray florets and yellow green-colored disc florets; excellent postproduction longevity; and relatively tolerant to low and high temperatures.

Description

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DLFBLAN1’.

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 ‘DLFBLAN1’.

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 attractive inflorescences, strong flowering stems and excellent postproduction longevity.

The new Chrysanthemum plant originated from a cross-pollination on Mar. 17, 2011 of a proprietary selection of Chrysanthemum x morifolium identified as code number DB 33767 as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number DB 34154 as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands on May 25, 2012.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since May 25, 2012 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 ‘DLFBLAN1’. These characteristics in combination distinguish ‘DLFBLAN1’ as a new and distinct Chrysanthemum plant:

    • 1. Upright plant habit; vigorous growth habit.
    • 2. Dark green-colored leaves.
    • 3. Uniform and freely flowering habit.
    • 4. Strong upright flowering stems with numerous inflorescences.
    • 5. Anemone-type inflorescences with white-colored ray florets and yellow green-colored disc florets.
    • 6. Excellent postproduction longevity.
    • 7. Relatively tolerant to low and high temperatures.

Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics:

    • 1. Disc florets of plants of the new Chrysanthemum are more green in color than disc florets of plants of the female parent selection.
    • 2. Ray floret apices of plants of the new Chrysanthemum are more pointed than and not as rounded as ray floret apices 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 have anemone-type inflorescences whereas plants of the male parent selection have single-type inflorescences.
    • 2. Disc florets of plants of the new Chrysanthemum are yellow green in color whereas disc florets of plants of the male parent selection are yellow in color.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Deliradost’, not patented. In side-by-side comparisons plants of the new Chrysanthemum differ primarily from plants of ‘Deliradost’ in the following characteristics:

    • 1. Disc florets of plants of the new Chrysanthemum are more green in color than disc florets of plants of ‘Deliradost’.
    • 2. Ray floret apices of plants of the new Chrysanthemum are more pointed than and not as rounded as ray floret apices of ‘Deliradost’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘DLFCAPO1’, not patented. In side-by-side comparisons plants of the new Chrysanthemum differ primarily from plants of ‘DLFCAPO1’ in disc floret color as disc florets of plants of the new Chrysanthemum are more green in color than disc florets of plants of ‘DLFCAPO1’.

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 ‘DLFBLAN1’ grown as a spray-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 ‘DLFBLAN1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the 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 22° C., night temperatures ranged from 20° C. to 25° C. and light levels averaged 8 klux. Plants were grown as single-stem plants and were ten 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.
