Abstract

A distinct cultivar of Chrysanthemum plant named ‘Yofire Island’, characterized by its uniform and upright plant habit; strong and freely branching growth habit; dark green glossy foliage; uniform and freely flowering habit; early flowering, eight-week response time; large daisy-type inflorescences that are about 11.7 cm in diameter; red and yellow bi-colored ray florets; and good postproduction longevity with plants maintaining good substance and color for at least four weeks in an interior environment.

Description

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 ‘Yofire Island’.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventors in Fort Myers, Fla. and Salinas, Calif. The objective of the breeding program is to create new 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 Inventors in October, 1994, in Salinas, Calif., of the Chrysanthemum cultivar Rage, disclosed in U.S. Plant Pat. No. 8,770, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as code number YB-5547, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Salinas, Calif. The selection of this plant was based on its uniform plant growth habit, desirable inflorescence form and 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 July, 1996. 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 Yofire Island 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, wihout, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yofire Island’. These characteristics in combination distinguish ‘Yofire Island’ as a new and distinct Chrysanthemum:
1. Uniform and upright plant habit.
2. Strong and freely branching growth habit.
3. Dark green glossy foliage.
4. Uniform and freely flowering habit.
5. Can be grown as a disbud or spray-type.
6. Early flowering, eight-week response time.
7. Large daisy-type inflorescences that are about 11.7 cm in diameter.
8. Red and yellow bi-colored ray florets.
9. Good postproduction longevity with plants maintaining good substance and color for at least 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 bright red and yellow bi-colored ray florets whereas plants of the female parent selection have solid bright red-colored ray florets.
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 bright red and yellow bi-colored ray florets whereas plants of the male parent selection have light pink-colored ray florets.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Pelee, disclosed in U.S. Plant Pat. No. 8,464. In side-by-side comparisons conducted by the Inventors in Salinas, Calif., plants of the new Chrysanthemum differed from plants of the cultivar Pelee in the following characteristics:
1. Plants of the new Chrysanthemum had a more uniform plant habit and flowering response than plants of the cultivar Pelee.
2. Plants of the new Chrysanthemum had darker green foliage than plants of the cultivar Pelee.
3. Plants of the new Chrysanthemum flowered about four to five days earlier than plants of the cultivar Pelee.
Plants of the new Chrysanthemum can also be compared to plants of the cultivar Yococoa Beach, disclosed in U.S. Plant Pat. No. 12,317. In side-by-side comparisons conducted by the Inventors in Salinas, Calif., plants of the new Chrysanthemum differed from plants of the cultivar Yococoa Beach in the following characteristics:
1. Plants of the new Chrysanthemum had a more uniform plant habit than plants of the cultivar Yococoa Beach.
2. Ray floret color of plants of the new Chrysanthemum was brighter and more vivid than ray floret color of plants of the cultivar Yococoa Beach.
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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yofire Island’ grown as a disbud-type.
The photograph on the second sheet comprises a close-up view of typical inflorescences of ‘Yofire Island’ grown as a disbud-type.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown and flowered during the summer 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 pinching, the photoinductive short day/long night treatments were started. Plants used for this description were grown as disbud-types. Measurements and numerical values represent averages of typical flowering plants.
