Title: Chrysanthemum Plant Named ‘Yodarlene’. Applicant: Mark A. Smith Filed concurrently.

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 ‘Yojillian’.

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, 2001, in Salinas, Calif. of a proprietary selection of Chrysanthemum×morifolium identified as code number 98-M307, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 98-M394, 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-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 Yojillian 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 ‘Yojillian’. These characteristics in combination distinguish ‘Yojillian’ 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. Decorative-type inflorescences with elongated oblong to ligulate-shaped ray florets.
  • 5. Lavender-colored ray florets.
  • 6. Natural season flowering about September 12^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 flowered earlier than plants of the female parent selection when grown under natural season conditions.
  • 2. Plants of the new Chrysanthemum flowered more uniformly than plants of the female parent selection.
  • 3. Ray florets of plants of the new Chrysanthemum were lavender in color whereas ray florets of plants of the female parent selection were yellow in color.

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

• • 1. Plants of the new Chrysanthemum were more mounded than plants of the male parent selection.
  • 2. Plants of the new Chrysanthemum flowered earlier than plants of the male parent selection when grown under natural season conditions.
  • 3. Plants of the new Chrysanthemum and the male parent selection differed in inflorescence form.
  • 4. Plants of the new Chrysanthemum and the male parent selection differed in ray floret coloration as plants of the male parent selection had purple-colored ray florets.

Plants of the new Chrysanthemum differ from plants of the cultivar Yodarlene, disclosed in a U.S. Plant patent application Ser. No. 11/641,397 filed concurrently, primarily in time to flower and ray floret coloration.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Debonair, disclosed in U.S. Plant Pat. No. 5,324. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Debonair in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more mounded than plants of the cultivar Debonair.
  • 2. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Debonair.
  • 3. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Debonair.
  • 4. Plants of the new Chrysanthemum and the cultivar Debonair differed slightly in ray floret coloration.

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 at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Yojillian.’.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Yojillian’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Pendleton, S.C. during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial garden Chrysanthemum production. During the production of the plants, day temperatures averaged 32° C. and night temperatures averaged 21° C. Plants were grown in 15-containers and exposed to long day/short night conditions for about three weeks, then exposed to natural season photoinductive conditions. 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.
