Chrysanthemum plant named ‘Yocheryl’

Abstract

A distinct cultivar of Chrysanthemum plant named ‘Yocheryl’, characterized by its uniformly mounded plant habit; glossy dark green foliage; decorative-type inflorescences that are about 4.3 cm in diameter; attractive lavender ray florets; and numerous inflorescences per plant.

Description

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 Yocheryl.

The new cultivar 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 garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms and floret colors and good garden performance.

The new cultivar originated from a cross made by the Inventor in January, 1993, of the Dendranthema grandiflora cultivar Lynn (U.S. Plant Pat. No. 8,171) as the female, or seed, parent with an unidentified proprietary seedling selection as the male, or pollen, parent.

The cultivar Yocheryl was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Salinas, Calif., in May, 1994. The selection of this plant was based on its desirable inflorescence form and ray floret color.

Asexual reproduction of the new cultivar by terminal cuttings taken 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 Yocheryl 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 ‘Yocheryl’. These characteristics in combination distinguish ‘Yocheryl’ as a new and distinct cultivar:

1. Uniformly mounded plant habit.

2. Glossy dark green foliage.

3. Decorative-type inflorescences that are about 4.3 cm in diameter.

4. Attractive lavender ray florets.

5. Numerous inflorescences per plant.

The new Chrysanthemum is similar to the parent cultivar Lynn. However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Lynn in the following characteristics:

1. Plants of the new Chrysanthemum are larger and more flexible than plants of the cultivar Lynn.

2. Plants of the new Chrysanthemum flower about one week later than plants of the cultivar Lynn grown under natural season conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new cultivar.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Yocheryl’.

The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of the cultivar ‘Yocheryl’. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Floret and foliage colors in the photographs may differ 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 Leamington, Ontario, Canada, under conditions which approximate those generally used in commercial garden Chrysanthemum production. One rooted cutting was planted in a 15-cm container on Jul. 20, 1998 and plants were grown outdoors under natural season conditions. Measurements and numerical values represent averages for typical flowering containers.

Petiole diameter: About 2.5 mm. Color: Young foliage upper surface: Darker than 147A, glossy. Young foliage lower surface: Darker than 147B. Mature foliage upper surface: 147A, glossy. Mature foliage lower surface: 147B. Venation upper surface: 147A. Venation lower surface: 147B.

Inflorescence description:

Appearance.—Decorative-type inflorescence form with oblong to spatulate-shaped ray florets. Inflorescences borne on terminals above foliage, arising from leaf axils. Disk and ray florets arranged acropetally on a capitulum. One inflorescence per terminal with numerous inflorescences per plant, about 10 per lateral stem.

Flowering response.—Under natural season conditions, plants flower in early October in the Northern Hemisphere about 82 days after planting, and flower for at least three weeks depending on weather conditions.
