Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Deklindi White’, characterized by its daisy-type inflorescences with obovate-shaped, white-colored ray florets and yellowish green-colored disc florets; strong, upright and freely branching flowering stems; early and uniform flowering response; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Deklindi White’.

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 ‘Deklindi White’.

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 Nov. 26, 2003, in Hensbroek, The Netherlands, of a proprietary selection of Chrysanthemum identified as code number 01.5569,03, not patented, as the female, or seed, parent with a proprietary Chrysanthemum selection identified as code number 01.5636,01, 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 December, 2003, 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 Deklindi White 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 ‘Deklindi White’. These characteristics in combination distinguish ‘Deklindi White’ as a new and distinct cultivar:

- 1. Daisy-type inflorescences with obovate-shaped, white-colored ray florets and yellowish green-colored disc florets.
- 2. Strong, upright and freely branching flowering stems.
- 3. Early and uniform flowering response.
- 4. Good postproduction longevity

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Chrysanthemum were more freely branching than plants of the female parent selection.
- 2. Plants of the new Chrysanthemum were more freely flowering than plants of the female parent selection.
- 3. Flowering stems of plants of the new Chrysanthemum were longer lasting than flowering stems of plants of the female parent selection.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Chrysanthemum were less vigorous than plants of the male parent selection.
- 2. Plants of the new Chrysanthemum flowered about three to four days earlier than plants of the male parent selection.
- 3. Plants of the new Chrysanthemum and the male parent selection differed in ray floret color as plants of the male parent selection had pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Dekyen Grande, not patented. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Dekyen Grande in the following characteristics:

- 1. Plants of the new Chrysanthemum were more freely branching than plants of the cultivar Dekyen Grande.
- 2. Plants of the new Chrysanthemum had narrower leaves than plants of the cultivar Dekyen Grande.
- 3. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Dekyen Grande.
- 4. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Dekyen Grande.
- 5. Flowering stems of plants of the new Chrysanthemum were longer lasting than flowering stems of plants of the cultivar Dekyen Grande.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Chrysanthemum.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Deklindi White’.

The photograph at the top of the second sheet is a close-up view of the typical inflorescences of ‘Deklindi White’.

The photograph at the bottom of the second sheet is a close-up view of upper and lower surfaces of typical inflorescences and leaves of ‘Deklindi White’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown during the summer 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° C. to 30° C., night temperatures ranged from 18.5° C. to 24° C. and light levels were about five kilolux. Plants were pinched once and were about nine weeks from planting when the photographs and the description were taken.
