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 Yospringfield.
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 August, 1994, in Salinas, Calif., of the
Dendranthema grandiflora
cultivar Charm, disclosed in U.S. Plant Pat. No. 5,502, as the female, or seed, parent, with a proprietary Chrysanthemum seedling selection identified as code number YB-6145, as the male, or pollen, 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 Fort Myers, Fla., in November, 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 Fort Myers, Fla., 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 Yospringfield 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 ‘Yospringfield’. These characteristics in combination distinguish ‘Yospringfield’ as a new and distinct Chrysanthemum:
1. Upright, somewhat spreading, compact and uniformly mounded plant habit.
2. Freely branching habit.
3. Dark green leaves.
4. Uniform and very early flowering.
5. Large decorative disbud-type inflorescences that are about 11.5 cm in diameter.
6. Attractive lavender pink ray florets.
7. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.
The new Chrysanthemum can be compared to the parent Chrysanthemum cultivar Charm. 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 Charm in the following characteristics:
1. Plants of the new Chrysanthemum are less vigorous and shorter than plants of the cultivar Charm. Plants of the new Chrysanthemum require an additional week of long days to achieve the same finished height as plants of the cultivar Charm.
2. Plants of the new Chrysanthemum have slightly larger inflorescences than plants of the cultivar Charm.
3. Plants of the new Chrysanthemum flower about one week earlier than plants of the cultivar Charm.
4. Ray florets of plants of the new Chrysanthemum are narrower, longer and more numerous than ray florets of plants of the cultivar Charm.
