Abstract

A distinct cultivar of Aster plant named ‘Chelsea’, characterized by its vigorous and strong growth; rapid growth rate; bright green leaves; numerous inflorescences per flowering stem; white-colored ray florets; and good postproduction longevity.

Description

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Aster plant, botanically known as Aster novi-belgii and referred to by the cultivar name Chelsea.
The new Aster is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program was to develop new strong-growing cut flower Aster cultivars with attractive floret colors. The new Aster originated from a cross made by the Inventor of a proprietary Aster selection identified as code number 268, not patented, as the female, or seed, parent with a proprietary Aster selection identified as code number 1198, not patented, as the male, or pollen, parent. The new Aster was selected by the Inventor on the basis of its large inflorescence size and attractive ray floret color. Plants of the female parent selection 268 and plants of the new Aster differ in inflorescence size, leaf size and leaf color. Plants of the male parent selection 1198 and plants of the new Aster differ in ray floret color and leaf size.
Asexual reproduction of the new cultivar by terminal cuttings taken in De Lier, The Netherlands has shown that the unique features of this new Aster are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chelsea’. These characteristics in combination distinguish ‘Chelsea’ as a new and distinct cultivar:
1. Vigorous and strong growth; rapid growth rate.
2. Bright green leaves.
3. Numerous inflorescences per flowering stem.
4. White-colored ray florets.
5. Good postproduction longevity.
Compared to plants of the Aster cultivar Monte Cassino, not patented, plants of the new Aster have larger inflorescences, longer flowering stems and lorger leaves.
The cultivar Chelsea 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.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Aster, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Aster. The photograph comprises a side perspective view of a typical flowering stem of the new Aster.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe flowering plants of the new Aster grown in De Lier, The Netherlands, under conditions which approximate commercial cut Aster production in a glass-covered greenhouse. Plants used in the photographs and the description were about 12 weeks old. Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
