Chrysanthemum plant named ‘Yophyllis’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Yophyllis’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; daisy-type inflorescences with elongated oblong to ligulate-shaped ray florets; coral pink-colored ray florets; and natural season flowering about September 11th in the Northern Hemisphere.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yophyllis’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a garden Chrysanthemum and hereinafter referred to by the name ‘Yophyllis’.

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 originated from a cross-pollination made by the Inventor in January, 2003, in Salinas, Calif. of a proprietary selection of Chrysanthemum×morifolium identified as code number 00-M401, not patented, as the female, or seed, parent with the Chrysanthemum×morifolium cultivar Atlantico, disclosed in U.S. Plant patent application Ser. No. 09/550,149, now abandoned, 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-pollination in a controlled environment in Alva, Fla. in September, 2003.

Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in Alva, Fla. in December, 2003. 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

Plants of the cultivar Yophyllis have 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 ‘Yophyllis’. These characteristics in combination distinguish ‘Yophyllis’ as a new and distinct garden Chrysanthemum cultivar:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Uniform and freely flowering habit.
  • 4. Daisy-type inflorescences with elongated oblong to ligulate-shaped ray florets.
  • 5. Coral pink-colored ray florets.
  • 6. Natural season flowering about September 11^th in the Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Chrysanthemum were smaller than plants of the female parent selection.
  • 2. Plants of the new Chrysanthemum flowered more uniformly and about one week earlier than plants of the female parent selection when grown under natural season conditions.
  • 3. Plants of the new Chrysanthemum and the female parent selection differed in inflorescence form.
  • 4. Ray florets of plants of the new Chrysanthemum were lighter in color than ray florets of plants of the female parent selection.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the male parent, the cultivar Atlantico, in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered earlier than plants of the cultivar Atlantico when grown under natural season conditions.
  • 2. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Atlantico.
  • 3. Plants of the new Chrysanthemum and the cultivar Atlantico differed in ray floret color as plants of the cultivar Atlantico had yellow bronze-colored ray florets.
  • 4. Ray floret color of plants of the new Chrysanthemum faded slower than ray floret color of plants of the cultivar Atlantico.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yocamille, disclosed in U.S. Plant Pat. No. 13,791. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Yocamille in the following characteristics:

• • 1. Plants of the new Chrysanthemum flowered earlier than plants of the cultivar Yocamille when grown under natural season conditions.
  • 2. Plants of the new Chrysanthemum and the cultivar Yocamille differed in ray floret color as plants of the cultivar Yocamille had light pink-colored ray florets.
  • 3. Ray floret color of plants of the new Chrysanthemum faded slower than ray floret color of plants of the cultivar Yocamille.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum. The photograph show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum. The photograph comprises a side perspective view of a typical flowering plant of ‘Yophyllis’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Alva, Fla. during the winter in a polycarbonate-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden Chrysanthemum production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 18° C. Plants were grown in containers, exposed to long day/short night conditions and pinched about 17 days later. Three days before the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description were about three months old. 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.
