Description
BACKGOUND 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 ‘Yomarcelle’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Fort Myers, Fla. and Salinas, Calif. 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, small inflorescences with 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, 1997, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number YB-6500, not patented, as the female, or seed, parent with the Chrysanthemum cultivar Regal Desiree, disclosed in U.S. Plant Pat. No. 8,606, 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 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, 1998. 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 Yomarcelle 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 ‘Yomarcelle’. These characteristics in combination distinguish ‘Yomarcelle’ as a new and distinct Chrysanthemum:

1. Uniform, outwardly spreading and compact plant habit.

2. Freely branching growth habit.

3. Small dark green foliage.

4. Uniform and freely flowering habit.

5. Typically grown as a spray-type.

6. Very early flowering, six-week response time.

7. Small daisy-type inflorescences that are about 2.7 cm in diameter.

8. Purple-colored ray florets with white bases and bright yellow-colored disc florets.

9. Good postproduction longevity with plants maintaining good substance and color for more than four weeks in an interior environment.

10. No pollen produced.

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 purple ray florets whereas plants of the female selection have pink ray florets. In addition, plants of the new cultivar have smaller inflorescences than plants of the female selection.

Plants of the new Chrysanthemum differ primarily from plants of the male parent, the cultivar Regal Desiree, in ray floret coloration as plants of the new Chrysanthemum have lighter purple ray florets than plants of the cultivar Regal Desiree. In addition, plants of the new Chrysanthemum have a more outwardly spreading plant habit than plants of the cultivar Regal Desiree.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Dark Cherie, disclosed in U.S. Plant Pat. No. 8,830. In side-by-side comparisons conducted by the Inventor in Salinas, Calif., plants of the new Chrysanthemum differed from plants of the cultivar Dark Cherie in the following characteristics:

1. Plants of the new Chrysanthemum flowered more uniformly and about two weeks earlier than plants of the cultivar Dark Cherie.

2. Ray florets of plants of the new Chrysanthemum were darker in color than ray florets of plants of the cultivar Dark Cherie.

3. Plants of the new Chrysanthemum had better postproduction longevity than plants of the cultivar Dark Cherie.

Plants of the new Chrysanthemum also can be compared to plants of the cultivar Soft Cherie, disclosed in U.S. Plant Pat. No. 8,802. In side-by-side comparisons conducted by the Inventor in Salinas, Calif., plants of the new Chrysanthemum differed from plants of the cultivar Soft Cherie in the following characteristics:

1. Plants of the new Chrysanthemum flowered more uniformly and about two weeks earlier than plants of the cultivar Soft Cherie.

2. Ray florets of plants of the new Chrysanthemum were purple in color whereas ray florets of plants of the cultivar Soft Cherie were light pink in color.

3. Plants of the new Chrysanthemum had better postproduction longevity than plants of the cultivar Soft Cherie.

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. One week after pinching, the photoinductive short day/long night treatments were started. Plants used for this description were grown as spray-types. Measurements and numerical values represent averages of typical flowering plants.
