BOTANICALCLASSIFICATION/CULTIVAR DENOMINATION
Chrysanthemum.times.morifolium cultivar Little Firock.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum.times.morifolium and hereinafter referred to by the name `Little Firock`.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Fareham, Hampshire, United Kingdom. The objective of the breeding program is to create new potted Chrysanthemum cultivars with uniform plant growthhabit, desirable inflorescence form and floret colors, and good postproduction longevity.
The new Chrysanthemum originated from a cross made by the Inventor in February, 1998, in Fareham, Hampshire, United Kingdom, of a proprietary Chrysanthemum seedling selection identified as code number 96w 4, not patented, as the female, or seed,parent with a proprietary Chrysanthemum seedling selection identified as code number 201w 1, 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 progenyof the stated cross grown in a controlled environment in Fareham, Hampshire, United Kingdom. The selection of this plant was based on its desirable inflorescence form and purple and white bi-colored ray florets.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fareham, Hampshire, United Kingdom in February, 1999. Asexual reproduction by vegetative tip cuttings has shown that the unique features of this newChrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Little Firock 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 ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Little Firock`. These characteristics in combination distinguish `Little Firock` as a new and distinct Chrysanthemum:
1. Uniform and upright plant habit.
2. Strong and freely branching growth habit.
3. Dark green foliage.
4. Uniform flowering habit.
5. Can be grown as a disbud or spray-type.
6. Eight-week response time.
7. Large daisy-type inflorescences that are about 9.75 cm in diameter.
8. Purple and white bi-colored ray florets.
9. Good postproduction longevity with plants maintaining good substance and color for at least three weeks in an interior environment.
Plants of the new Chrysanthemum are similar to plants of the female parent selection in ray floret coloration, however plants of the new Chrysanthemum have smaller inflorescences 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 purple and white bi-colored ray florets whereas plants of the male parent selection havepurple-colored ray florets. In addition, plants of the new Chrysanthemum have larger inflorescences and flower earlier than plants of the male parent selection.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Yolompoc, disclosed in U.S. Plant Pat. No. 11,203. In side-by-side comparisons conducted by the Inventor in Fareham, Hampshire, United Kingdom, plants of the newChrysanthemum differed from plants of the cultivar Yolompoc in the following characteristics:
1. Plants of the new Chrysanthemum had larger leaves and inflorescences than plants of the cultivar Yolompoc.
2. Plants of the new Chrysanthemum had thicker and stronger stems than plants of the cultivar Yolompoc.
3. Plants of the new Chrysanthemum flowered about 5 days later than plants of the cultivar Yolompoc.
4. Plants of the new Chrysanthemum and the cultivar Yolompoc differed in ray floret coloration as plants of the new Chrysanthemum had purple and white bi-colored ray florets whereas plants of the cultivar Yolompoc had purple-colored ray florets.
Plants of the new Chrysanthemum can also be compared to plants of the cultivar Yonashville, disclosed in U.S. Plant Pat. No. 11,795. In side-by-side comparisons conducted by the Inventor in Fareham, Hampshire, United Kingdom, plants of the newChrysanthemum differed from plants of the cultivar Yonashville in the following characteristics:
1. Plants of the new Chrysanthemum were sturdier than plants of the cultivar Yonashville.
2. Plants of the new Chrysanthemum flowered about 10 days later than plants of the cultivar Yonashville.
3. Plants of the new Chrysanthemum and the cultivar Yonashville differed in ray floret coloration as plants of the new Chrysanthemum had purple and white bi-colored ray florets whereas plants of the cultivar Yonashville had pink-colored rayflorets.
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 fromthe color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.
The photograph at the top of the first sheet comprises a side perspective view of a typical flowering plant of `Little Firock` grown as a disbud-type.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of `Little Firock` grown as a disbud-type.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, version 1995, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and followingobservations and measurements describe plants grown and flowered during the summer and autumn in Leamington, Ontario, Canada, in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial pottedChrysanthemum production. 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 werestarted. Plants used for this description were grown as disbud-types. Measurements and numerical values represent averages of typical flowering plants. Botanical classification: Chrysanthemum.times.morifolium cultivar Little Firock.
