Abstract

A distinct cultivar of Chrysanthemum plant named ‘Yoeugene’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; freely branching habit; uniform and early flowering; numerous daisy-type inflorescences that are about 7.5 cm in diameter; initially yellow then bright pink-colored ray florets; slow maturing disc florets; and good postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.

Description

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 Yoeugene.
The new Chrysanthemum 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 pot-type Chrysanthemum cultivars having desirable inflorescence forms and floret colors and good post-production longevity.
The new Chrysanthemum originated from a cross made by the Inventor in October, 1994, in Salinas, Calif., of a proprietary Chrysanthemum seedling selection identified as code number YB-6364 as the female, or seed, parent, with the commercial Chrysanthemum cultivar Miramar, disclosed in U.S. Plant Pat. No. 7,469, as the male, or pollen, parent.
The new Chrysanthemum was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Fort Myers, Fla., in November, 1995. The selection of this plant was based on its desirable inflorescence form and floret colors and good post-production longevity.
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 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, and variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yoeugene’. These characteristics in combination distinguish ‘Yoeugene’ as a new and distinct Chrysanthemum:
1. Upright, outwardly spreading and uniformly mounded plant habit.
2. Freely branching habit, very full and dense plants.
3. Uniform and early flowering.
4. Floriferous, numerous daisy-type inflorescences that are about 7.5 cm in diameter.
5. Initially yellow then bright pink-colored ray florets.
6. Slow maturing disc florets.
7. Good postproduction longevity with inflorescences and leaves maintaining good substance and color for about three or four weeks in an interior environment.
The new Chrysanthemum can be compared to the Chrysanthemum cultivar Regal Davis, disclosed in U.S. Plant Pat. No. 8,292. However in side-by-side comparisons in Salinas, Calif., and Leamington, Ontario, Canada, under commercial practice, plants of the new Chrysanthemum differ from plants of the cultivar Regal Davis in the following characteristics:
1. Plants of the new Chrysanthemum are larger and more vigorous than plants of the cultivar Regal Davis.
2. Leaves of the new Chrysanthemum are larger and less likely to fleck than leaves of the cultivar Regal Davis. In addition, plants of the new Chrysanthemum have better foliage retention than plants of the cultivar Regal Davis.
3. Plants of the new Chrysanthemum flower about four or five days earlier than plants of the cultivar Regal Davis.
4. Inflorescences of the new Chrysanthemum are larger than inflorescences of the cultivar Regal Davis.
5. Ray florets of the new Chrysanthemum are initially yellow whereas ray florets of the cultivar Regal Davis are initially pink. Mature ray florets of the new Chrysanthemum are lighter pink than ray florets of the cultivar Regal Davis.
6. Ray florets of the new Chrysanthemum are convex in cross-section whereas ray florets of the cultivar Regal Davis are flat to concave.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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.
The photograph at the top of the first sheet comprises a top perspective view of a typical flowering plant of ‘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 Yoeugene.
The photograph at the top of the second sheet comprises a side perspective view of typical flowering plants of ‘Yoeugene’ (left) and ‘Regal Davis’ (right).
The photograph at the bottom of the second sheet comprises a close-up view of upper surfaces of typical inflorescences and leaves of plants of ‘Yoeugene’ (left) and ‘Regal Davis’ (right). Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
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 in Salinas, Calif., and 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 spray-types. Measurements and numerical values represent averages of typical flowering plants.
