ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as
Dendranthema grandiflora
and hereinafter referred to by the cultivar name Yocasper.
The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. The objective of the breeding program is to create new pot-type Chrysanthemum cultivars having desirable inflorescence forms and floret colors and good post-production longevity.
The new Chrysanthemum originated from a cross made by the Inventor in January, 1994, in Salinas, Calif., of a the Chrysanthemum cultivar Claro, disclosed in U.S. Plant Pat. No. 6,946 as the male, or pollen, parent, with an unidentified Chrysanthemum seedling selection as the female, or seed, parent.
The new Chrysanthemum was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Salinas, Calif., in May, 1995. The selection of this plant was based on its desirable inflorescence form and floret colors and good post-production longevity.
Asexual reproduction of the new Chrysanthemum by terminal cuttings harvested in a controlled environment in Salinas, Calif., 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 Yocasper has 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 ‘Yocasper’. These characteristics in combination distinguish ‘Yocasper’ as a new and distinct Chrysanthemum:
1. Upright, outwardly spreading and uniformly mounded plant habit.
2. Freely branching habit.
3. Dark green leaves.
4. Uniform and early flowering.
5. Moderately vigorous and strong plant growth.
6. Large decorative quill-type inflorescences that are about 10.5 cm in diameter when grown as a disbud.
7. Ray floret color that is initially light yellow then becoming white with subsequent development giving the inflorescence a yellow and white bi-colored appearance.
8. Good postproduction longevity with inflorescences and leaves maintaining good substance and color for about three weeks in an interior environment.
The new Chrysanthemum can be compared to the Chrysanthemum cultivar Phoenix, disclosed in U.S. Plant Pat. No. 8,843. However in side-by-side comparisons in Salinas, Calif., and Leamington, Ontario, Canada, under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Phoenix in the following characteristics:
1. Plants of the new Chrysanthemum are more outwardly spreading than plants of the cultivar Phoenix.
2. Plants of the new Chrysanthemum are more vigorous than plants of the cultivar Phoenix.
3. Ray florets of the new Chrysanthemum are broader, more upright and have more open apices than ray florets of the cultivar Phoenix.
4. Ray florets of the new Chrysanthemum are initially yellow becoming white with subsequent development whereas ray florets of plants of the cultivar Phoenix are light tan in color.
