ABSTRACT:

Botanical classification/cultivar designation:
Chrysanthemum×morifolium
cultivar Yonorwich.
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 ‘Yonorwich’.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Fort Myers, Fla. 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 and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.
The new Chrysanthemum originated from a cross-pollination made by the Inventor in January, 1999, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number YB-4637, not patented, as the female, or seed, parent with a proprietary Chrysanthemum seedling selection identified as code number YB-6489, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor in November, 1999, as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Fort Myers, Fla. The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.
Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in February, 2000. 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 Yonorwich 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 ‘Yonorwich’. These characteristics in combination distinguish ‘Yonorwich’ as a new and distinct Chrysanthemum:
1. Uniform and outwardly spreading plant habit.
2. Strong and freely branching growth habit.
3. Dark green-colored foliage.
4. Uniform flowering response and habit.
5. Early flowering, eight-week response time.
6. Decorative-type inforescences.
7. Red-colored ray florets.
8. Good postproduction longevity with plants maintaining good substance and color for about four to five weeks in an interior environment.
Plants of the new Chrysanthemum differ primarily from plants of the female parent selection primarily in ray floret color as plants of the female parent selection have orange-colored ray florets.
Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in the following characteristics:
1. Plants of the new Chrysanthemum flower about one week earlier than plants of the male parent selection.
2. Plants of the new Chrysanthemum have decorative inflorescences whereas plants of the male parent selection have semi-double inflorescences.
Plants of the new Chrysanthemum can be compared to plants of the cultivar Red Delano, disclosed in U.S. Plant Pat. No. 8,345. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Red Delano in the following characteristics:
1. Plants of the new Chrysanthemum were not as vigorous as plants of the cultivar Red Delano.
2. Plant habit of the new Chrysanthemum was more uniform than plant habit of plants of the cultivar Red Delano.
3. Plants of the new Chrysanthemum flowered about three to four days earlier than plants of the cultivar Red Delano.
4. Ray florets of plants of the new Chrysanthemum were lighter red in color than ray florets of plants of the cultivar Red Delano.
