Abstract
A distinct cultivar of Chrysanthemum plant named ‘Ivory Yoeugene’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; freely branching, dense and full plants; dark green foliage; uniform flowering; early flowering, eight-week response time; freely flowering with about six inflorescences per lateral stem; daisy-type inflorescences that are about 7.6 cm in diameter; ivory-colored ray florets and bright yellow disc florets; and excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.
Description
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 Ivory Yoeugene.
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 Yoeugene, disclosed in U.S. Plant Pat. No. 11,917, to X-ray radiation in September, 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 March, 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.
The cultivar Ivory Yoeugene 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 ‘Ivory Yoeugene’. These characteristics in combination distinguish ‘Ivory Yoeugene’ 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. Early flowering, eight-week response time.
6. Freely flowering; about six inflorescences per lateral stem.
7. Daisy-type inflorescences that are about 7.6 cm in diameter.
8. Ivory-colored ray florets and bright yellow disc florets.
9. Excellent postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.
Compared to plants of the parent cultivar, Yoeugene, ray florets of plants of the new Chrysanthemum are ivory in color whereas ray florets of plants of the cultivar Yoeugene are rose pink in color. In addition, plants of the new Chrysanthemum flower about one or two days later than plants of the cultivar Yoeugene.
The accompanying colored photographs illustrate the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which more accurately describe the actual colors of the Chrysanthemum.
The photograph at the top of the first sheet comprises a top perspective view of a typical flowering plant of ‘Ivory Yoeugene’.
The photograph at the bottom of the first sheet comprises a close-up view of upper (left) and lower (right) surfaces of typical inflorescences and upper (left) and lower (right) surfaces of typical leaves of the cultivar Ivory Yoeugene.
The photograph at the top of the second sheet comprises a side perspective view of typical flowering plants of ‘Ivory Yoeugene’ (left) and ‘Yoeugene’ (right).
The photograph at the bottom of the second sheet comprises a close-up view of typical inflorescences of plants of ‘Ivory Yoeugene’ (left) and ‘Yoeugene’ (right).
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown and flowered during the Autumn in Leamington, Ontario, Canada, under greenhouse conditions which approximate those generally used in commercial potted Chrysanthemum production. Four unrooted cuttings were directly stuck in a 15-cm container and pinched once. Plants used for this description were grown as center budded-types. Measurements and numerical values represent averages of typical flowering plants.
Botanical classification: Dendranthema grandiflora cultivar Ivory Yoeugene.
Commercial classification: Daisy center budded-type potted Chrysanthemum.
Parentage: Induced mutation of the Dendranthema grandiflora cultivar Yoeugene, disclosed in U.S. Plant Pat. No. 11,917.
Propagation:
Type.—Terminal tip cuttings.
Time to rooting.—Seven to ten days with soil temperatures of 21° C.
Rooting habit.—Fine, fibrous and well-branched.
Plant description:
Appearance.—Herbaceous daisy potted Chrysanthemum typically grown as a center budded-type. Inverted triangle; stems upright and outwardly spreading giving a uniformly mounded appearance to the plant. Freely branching; about three or four lateral branches develop after removal of terminal apex (pinching); dense and full plants.
Plant height.—About 30 cm.
Plant width.—About 44 cm.
Foliage description.—Arrangement: Alternate. Length: About 7.2 cm. Width: About 5.2 cm. Apex: Cuspidate. Base: Cuneate. Margin: Palmately lobed, sinuses between lateral lobes mostly divergent. Texture: Upper and lower surfaces with very fine pubescence; veins prominent on lower surface. Petiole length: About 2.7 cm. Petiole diameter: About 3 mm. Color: Young foliage upper surface: 147A. Young foliage lower surface: Slightly darker than 147B. Mature foliage upper surface: 147A, shiny. Mature foliage lower surface: 147B. Venation upper surface: 147A to 147B.
