Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Rosy Yovictoria’, characterized by its compact, upright and somewhat outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; decorative-type inflorescences with elongated oblong-shaped ray florets; red purple-colored ray florets; and natural season flowering in late September in the Northern Hemisphere.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Rosy Yovictoria.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Rosy Yovictoria’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.
The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Yovictoria, disclosed in U.S. Plant Pat. No. 13,799. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the cultivar Yovictoria in a controlled environment in Alva, Fla. in April, 2002. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and good garden performance.
Asexual reproduction of the new cultivar by terminal vegetative cuttings in a controlled environment in Alva, Fla. since June, 2002, 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 Rosy Yovictoria 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 ‘Rosy Yovictoria’. These characteristics in combination distinguish ‘Rosy Yovictoria’ as a new and distinct cultivar:
    • 1. Compact, upright and somewhat outwardly spreading plant habit.
    • 2. Freely branching habit; dense and full plants.
    • 3. Uniform and freely flowering habit.
    • 4. Decorative-type inflorescences with elongated oblong-shaped ray florets.
    • 5. Red purple-colored ray florets.
    • 6. Natural season flowering in late September in the Northern Hemisphere.
In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the parent, the cultivar Yovictoria, primarily in ray floret coloration as plants of the cultivar Yovictoria had lavender-colored ray florets. In addition, plants of the new Chrysanthemum flowered a couple of days later than plants of the cultivar Yovictoria when grown under natural season conditions.
Plants of the new Chrysanthemum differ from plants of the cultivar Zesty Yovictoria, disclosed in U.S. Plant Pat. No. 15,323, primarily in ray floret coloration.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Helen, disclosed in U.S. Plant Pat. No. 9,793. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Helen in the following characteristics:
    • 1. Plants of the new Chrysanthemum were more rounded and mounding than plants of the cultivar Helen.
    • 2. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Helen.
    • 3. Plants of the new Chrysanthemum flowered about three days later than plants of the cultivar Helen when grown under natural season conditions.
    • 4. Plants of the new Chrysanthemum flowered a few days earlier than plants of the cultivar Helen when grown under artificial short day/long night photoperiodic conditions.
Plants of the new Chrysanthemum can also be compared to plants of the Chrysanthemum cultivar Savona, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Savona in the following characteristics:
    • 1. Plants of the new Chrysanthemum were smaller and more rounded than plants of the cultivar Savona.
    • 2. Plants of the new Chrysanthemum flowered about ten days earlier than plants of the cultivar Savona when grown under natural season conditions.
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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘Rosy Yovictoria’ grown in a container.
The photograph on the second sheet comprises a close-up view of typical inflorescences of the cultivar ‘Rosy Yovictoria’.
 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 following observations and measurements describe plants grown in Alva, Fla. during the winter in a fiberglass-covered greenhouse under conditions and practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was planted in a 15.25-cm container in early December, 2002. Plants were pinched one time, that is, the terminal apex was removed to enhance branching, at the end of December. One week after the pinch, plants were exposed to short day/long light photoperiodic treatments until flowering. During the production of the plants, day temperatures averaged 26° C. and night averaged 18° C. Measurements and numerical values represent averages for typical flowering plants.
