ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as
Dendranthema grandiflora
and referred to by the cultivar name Yoroxanne.
The new cultivar 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 garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms and floret colors and good garden performance.
The new cultivar originated from a cross made by the Inventor in January, 1993, of the
Dendranthema grandiflora
cultivar Lynn (U.S. Plant Pat. No. 8,171) as the female, or seed, parent with an unidentified proprietary seedling selection as the male, or pollen, parent.
The cultivar Yoroxanne 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, 1994. The selection of this plant was based on its desirable inflorescence form and ray floret color.
Asexual reproduction of the new cultivar by terminal cuttings taken 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 Yoroxanne 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 ‘Yoroxanne’. These characteristics in combination distinguish ‘Yoroxanne’ as a new and distinct cultivar:
1. Uniformly mounded, dense and relatively compact plant habit.
2. Glossy dark green leaves.
3. Decorative-type inflorescences that are about 4.6 cm in diameter.
4. Attractive white ray florets with purple apices.
5. Numerous inflorescences per plant.
The new Chrysanthemum is similar to the
Dendranthema grandiflora
cultivar Empire Spotlight, disclosed in U.S. Plant Pat. No. 9,933. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Empire Spotlight in the following characteristics:
1. Plants of the new Chrysanthemum flower about ten days later than plants of the cultivar Empire Spotlight under natural season conditions.
2. Plants of the new Chrysanthemum have slightly smaller inflorescences than plants of the cultivar Empire Spotlight.
