USPP19420P2 - Chrysanthemum plant named ‘Kistar Dark’ - Google Patents

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Kistar Dark’, characterized by its compact, upright and mounded plant habit; dark green-colored foliage; uniform flowering response; early flowering habit; freely flowering habit; decorative-type inflorescences with dark orange-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Kistar Dark’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a potted Chrysanthemum and hereinafter referred to by the name ‘Kistar Dark’.

The new Chrysanthemum is a naturally-occurring branch mutation of the Chrysanthemum×morifolium cultivar Kistar, not patented. The new Chrysanthemum was discovered by the Inventor on a single flowering plant in a population of plants of ‘Kistar’ in a controlled environment in Monster, The Netherlands in September, 2005.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in 's-Gravenzande, The Netherlands in November, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Kistar Dark have 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 ‘Kistar Dark’. These characteristics in combination distinguish ‘Kistar Dark’ as a new and distinct potted Chrysanthemum cultivar:

• • 1. Compact, upright and mounded plant habit.
  • 2. Dark green-colored foliage.
  • 3. Uniform flowering response.
  • 4. Early flowering habit, eight-week response time.
  • 5. Freely flowering habit.
  • 6. Decorative-type inflorescences with dark orange-colored ray florets.
  • 7. Good postproduction longevity with plants maintaining good substance and color for about four to five weeks in an interior environment.

Plants of the new Chrysanthemum differ from plants of the parent, the cultivar Kistar, primarily in leaf and ray floret coloration as plants of the new Chrysanthemum have darker colored leaves and ray florets than plants of the cultivar Kistar.

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

• • 1. Plants of the new Chrysanthemum and the cultivar Kilargo differed slightly in leaf coloration.
  • 2. Inflorescences of plants of the new Chrysanthemum and the cultivar Kilargo differed in ray floret coloration as plants of the cultivar Kilargo had red purple-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show 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.

The photograph at the top of the sheet comprises a side perspective view of typical flowering plant of ‘Kistar Dark’.

The photograph at the bottom of the sheet is a close-up view of the upper (left) and lower (right) surfaces of typical leaves and inflorescences of ‘Kistar Dark’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 's-Gravenzande, The Netherlands during the winter in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial potted Chrysanthemum production. During the production of the plants, day and night temperatures were about 17° C. to 18° C. Plants were grown under photoinductive short day/long night treatments. Plants used in the photographs and for the description were not pinched and were about ten weeks old. 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.
