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 Bright Stephanie.
The new cultivar is a product of a mutation induction breeding program conducted by the inventor in Fort Myers, Fla., and Salinas, Calif. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having with desirable inflorescence form and color and good garden performance.
The new cultivar originated by exposing unrooted cuttings of the Chrysanthemum cultivar Stephanie (disclosed in U.S. Plant Pat. No. 9,445) to X-ray radiation at a level of 2,000 rads in Jun. 1994. Following the radiation treatment, the cuttings were rooted and terminal apices were removed (pinched) three times to promote lateral branch development. After lateral branches from the third pinch reached sufficient size, terminal cuttings were harvested, planted and flowered in a controlled environment in Salinas, Calif. The cultivar Bright Stephanie was discovered and selected by the inventor as a single flowering plant within this population in December, 1994. The selection of this plant was based on its desirable ray floret color.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Salinas, Calif., has shown that the unigue features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Bright Stephanie 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 repeatly observed and are determined to be the unique characteristics of ‘Bright Stephanie’. These characteristics in combination distinguish ‘Bright Stephanie’ as a new and distinct cultivar:
1. Uniformly mounded plant habit.
2. Relatively early flowering.
3. Daisy-type inflorescences that are about 5.1 cm in diameter.
4. Attractive bright yellow ray florets and darker yellow disc florets.
5. Numerous inflorescences per plant.
The new Chrysanthemum is similar to the parent cultivar Stephanie. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Stephanie in the following characteristics:
1. Plants of the new Chrysanthemum do not flower as uniformly as plants of the cultivar Stephanie.
2. Plants of the new Chrysanthemum have bright yellow ray florets and darker yellow disc florets whereas plants of the cultivar Stephanie have white ray florets and golden yellow disc florets.
3. Plants of the new Chrysanthemum are more compact than plants of the cultivar Stephanie.
4. Plants of the new Chrysanthemum flower earlier than plants of the cultivar Stephanie.
5. Ray floret color of plants of the new Chrysanthemum fades more than ray floret color of plants of the cultivar Stephanie.
