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 Amber Pomona.
The new Chrysanthemum is a product of a mutation induction breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the program is to create new Chrysanthemum cultivars with desirable inflorescence form and floret colors, good substance, and excellent post-production longevity.
The new Chrysanthemum originated by exposing unrooted cuttings of the Chrysanthemum cultivar Orange Pomona, disclosed in U.S. Plant Pat. No. 11,176, to X-ray radiation in June, 1997, in Fort Myers, Fla. 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 Fort Myers, Fla. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within this population in January, 1998. The selection of this plant was based on its desirable inflorescence form and ray floret color.
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 Amber Pomona 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 ‘Amber Pomona’. These characteristics in combination distinguish ‘Amber Pomona’ as a new and distinct Chrysanthemum:
1. Upright, outwardly spreading and uniformly mounded plant habit.
2. Freely branching, dense and full plants.
3. Dark green foliage.
4. Uniform flowering.
5. Nine-week flowering response time.
6. Large decorative-type inflorescences that are about 9.4 cm in diameter.
7. Light orange bronze-colored ray florets.
8. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for at least three weeks in an interior environment.
Compared to plants of the parent cultivar, Orange Pomona, plants of the new Chrysanthemum have much lighter orange bronze-colored ray florets.
