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 Festive New Yoorleans.
The new Chrysanthemum is a product of a mutation induction breeding program conducted by the Inventor in Fort Myers, Fla. and Salinas, Calif. 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 New Yoorleans, disclosed in U.S. Plant Pat. No. 11,215, to X-ray radiation in December, 1996, 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 Salinas, Calif. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within this population in April, 1997. 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 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 Festive New Yoorleans 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 ‘Festive New Yoorleans’. These characteristics in combination distinguish ‘Festive New Yoorleans’ as a new and distinct Chrysanthemum:
1. Upright plant habit.
2. Freely branching, dense and full plants.
3. Dark green foliage.
4. Uniform flowering.
5. Early flowering, eight-week response time.
6. Very freely flowering; about ten inflorescences per lateral stem.
7. Daisy-type inflorescences that are about 7.1 cm in diameter.
8. Bi-colored ray florets with light yellow bases and reddish purple apices and bright yellow disc florets.
9. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for about three weeks in an interior environment.
Compared to plants of the parent cultivar, New Yoorleans, ray florets of plants of the new Chrysanthemum are light yellow with reddish purple apices whereas ray florets of plants of the cultivar New Yoorleans are white with purple apices. In addition, plants of the new Chrysanthemum flower about one or two days later than plants of the cultivar New Yoorleans.
