Abstract

A new and distinct cultivar of cut flower Aster plant named ‘Esmore’, characterized by its strong and erect flowering stems; symmetrical branching habit with long lateral branches; medium green-colored foliage; early, uniform and freely flowering habit; daisy-type inflorescences with white-colored ray florets; and excellent postproduction longevity.

Description

Botanical classification/cultivar designation: Aster hybrida cultivar Esmore.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of cut flower Aster plant, botanically known as Aster hybrida and hereinafter referred to by the name ‘Esmore’.
The new Aster is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program is to create new cut flower Aster cultivars with durable leaves, strong stems, desirable floret colors and good postproduction longevity.
The new Aster originated from a cross-pollination made by the Inventor in El Quinche, Pichincha, Ecuador in February, 2000, of a proprietary Aster selection identified as Line 36, not patented, as the female, or seed, parent with an unknown Aster selection, not patented, as the male, or pollen, parent. The new Aster was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in El Quinche, Pichincha, Ecuador. The selection of this plant was based on its durable foliage, strong stems and desirable inflorescence form and attractive ray floret color.
Asexual reproduction of the new Aster by vegetative tip cuttings was first conducted in El Quinche, Pichincha, Ecuador in January, 2001. Asexual reproduction by cuttings 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 cultivar Esmore has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Esmore’. These characteristics in combination distinguish ‘Esmore’ as a new and distinct cut flower Aster:
    • 1. Strong and erect flowering stems.
    • 2. Symmetrical branching habit with long lateral branches.
    • 3. Medium green-colored foliage.
    • 4. Early, uniform and freely flowering habit.
    • 5. Daisy-type inflorescences with white-colored ray florets.
    • 6. Excellent postproduction longevity.
Plants of the new Aster can be compared to plants of the female parent selection. Plants of the new Aster differ from plants of the female parent selection primarily in plant height as plants of the new Aster are taller than plants of the female parent selection. In addition, plants of the new Aster have more ray florets per inflorescence than plants of the female parent selection.
Plants of the new Aster can be compared to plants of the cultivar Sun Carlo, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador plants of the new Aster differed from plants of the cultivar Sun Carlo in the following characteristics:
    • 1. Plants of the new Aster were taller than plants of the cultivar Sun Carlo.
    • 2. Plants of the new Aster had larger leaves than plants of the cultivar Sun Carlo.
    • 3. Plants of the new Aster flowered about one week earlier than plants of the cultivar Sun Carlo.
    • 4. Inflorescences of plants of the new Aster had more ray and disc florets than inflorescences of plants of the cultivar Sun Carlo.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Aster.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Esmore’.
The photograph on the second sheet are close-up views of a typical inflorescence of ‘Esmore’ (left) and a typical inflorescence of ‘Sun Carlo’ (left).
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown and flowered during the fall and winter in El Quinche, Pichincha, Ecuador, in an outdoor nursery and under conditions which approximate those generally used in commercial cut flower Aster production. During the production of these plants, day temperatures ranged from 12 to 30° C. and night temperatures ranged from 5 to 12° C. Plants were about four to six months from planting rooted young plants when the photographs and the botanical description were taken.
