Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yobrunswick.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Yobrunswick’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Fort Myers, Fla. The objective of the program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in April, 2000, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number YB-A2427, not patented, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as code number YB-6604, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor in March, 2001, as a single flowering plant from within the resulting progeny of the stated cross-pollination grown in a controlled environment in Fort Myers, Fla.

The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in June, 2001. 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

The cultivar Yobrunswick has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yobrunswick’. These characteristics in combination distinguish ‘Yobrunswick’ as a new and distinct Chrysanthemum:

    • 1. Uniform and outwardly spreading plant habit.
    • 2. Strong and freely branching growth habit.
    • 3. Dark green-colored foliage.
    • 4. Uniform flowering response and habit.
    • 5. Typically grown as a spray-type.
    • 6. Early flowering, eight week response time.
    • 7. Daisy-type inflorescences with spoon-shaped ray florets.
    • 8. White-colored ray florets.
    • 9. Good postproduction longevity with plants maintaining good substance and color for about three weeks in an interior environment.

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ from plants of the female parent selection primarily in inflorescence form and ray floret coloration as plants of the female parent selection have anemone-type inflorescences with light pink-colored ray florets. In addition, plants of the new Chrysanthemum flower about one week later than plants of the female parent selection.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ from plants of the male parent selection primarily in ray floret shape and coloration as plants of the male parent selection have elongated oblong-shaped and pink-colored ray florets. In addition, disc florets of plants of the new Chrysanthemum do not produce pollen whereas disc florets of plants of the male parent selection produce pollen.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Yomankato, disclosed in U.S. Plant Pat. No. 13,057. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yomankato in the following characteristics:

    • 1. Plants of the new Chrysanthemum were taller and more outwardly spreading than plants of the cultivar Yomankato.
    • 2. Plants of the new Chrysanthemum and the cultivar Yomankato differed in inflorescence form as plants of the cultivar Yomankato had anemone-type inflorescences.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown and flowered during the autumn in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, the following conditions were measured: day temperatures, 21 to 27° C.; night temperatures, 17 to 19° C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cm containers, exposed to long day/short night conditions, and pinched once about two weeks later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
