Abstract

A distinct cultivar of Chrysanthemum plant named ‘Yoplymouth’, characterized by its uniform, upright and somewhat outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering habit; early flowering habit; numerous daisy-type inflorescences with spoon-shaped ray florets; red purple-colored ray florets with light purple-colored tubes; and excellent postproduction longevity with plants maintaining good substance and color for about four weeks in an interior environment.

Description

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Yoplymouth.
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 ‘Yoplymouth’.
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 breeding program is to create new compact potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor, desirable inflorescence form and floret colors, fast response time, and good postproduction longevity.
The new Chrysanthemum originated from a cross made by the Inventor in May, 1998, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number YB-3239, not patented, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as code number YB-5897, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Fort Myers, Fla. in March, 1999. The selection of this plant was based on its uniform plant growth habit, desirable inflorescence form and ray floret colors, fast response time, and excellent postproduction longevity.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in June, 1999. 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 Yoplymouth 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 ‘Yoplymouth’. These characteristics in combination distinguish ‘Yoplymouth’ as a new and distinct Chrysanthemum:
1. Uniform, upright and somewhat outwardly spreading plant habit.
2. Strong and freely branching growth habit.
3. Dark green-colored foliage.
4. Uniform flowering habit.
5. Early flowering, 7-week response time.
6. Numerous daisy-type inflorescences with spoon-shaped ray florets.
7. Red purple-colored ray florets with light purple-colored tubes.
8. Excellent postproduction longevity with plants maintaining good substance and color for about four weeks in an interior environment.
Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in ray floret coloration as plants of the new Chrysanthemum have red purple-colored ray florets whereas plants of the female parent selection have purple-colored ray florets. In addition, plants of the new Chrysanthemum flower about one week earlier than plants of the female parent selection.
Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in ray floret coloration as plants of the new Chrysanthemum have red purple-colored ray florets whereas plants of the male parent selection have purple-colored ray florets. In addition, plants of the new Chrysanthemum are shorter and are more freely branching than plants of the male parent selection.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Yoduluth, disclosed in U.S. Plant Pat. No. 11,993. In side-by-side comparisons conducted in Salinas, Calif., plants of the new Chrysanthemum differed from plants of the cultivar Yoduluth in the following characteristics:
1. Plants of the new Chrysanthemum were not as vigorous as plants of the cultivar Yoduluth.
2. Plants of the new Chrysanthemum flowered about two weeks earlier than plants of the cultivar Yoduluth.
3. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Yoduluth.
4. Ray florets of plants of the new Chrysanthemum had longer corolla tubes than ray florets of plants of the cultivar Yoduluth.
5. Ray florets of plants of the new Chrysanthemum were red purple in color whereas ray florets of plants of the cultivar Yoduluth were dark purple in color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ 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 plants of ‘Yoplymouth’ grown as spray-types.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of ‘Yoplymouth’ grown as spray-types.
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 fall 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 14 days later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the photographs and description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
