| Abstract: |
A new and distinct cultivar of cut flower Aster plant named `Esmart`, characterized by its strong erect flowering stems; symmetrical branching habit; dark green-colored foliage; uniform and freely flowering habit; decorative-type inflorescences with violet-colored ray florets; and good postproduction longevity. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of cut flower Aster plant named `Esmart`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Aster hybrida cultivar Esmart.
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 `Esmart`.
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, desirablefloret colors, and good postproduction longevity.
The new Aster originated from a cross-pollination made by the Inventor in El Quinche, Pichincha, Ecuador in August, 1999, of a proprietary Aster selection identified as breeding line 13, not patented, as the female, or seed, parent with anunknown 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 ElQuinche, Pichincha, Ecuador. The selection of this plant was based on its durable foliage, strong stems and desirable inflorescence form and ray floret color.
Asexual reproduction of the new Aster by vegetative tip cuttings was first conducted in El Quinche, Pichincha, Ecuador in August, 2000. Asexual reproduction by cuttings has shown that the unique features of this new Aster are stable andreproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Esmart 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 `Esmart`. These characteristics in combination distinguish `Esmart` as a new and distinct cut flower Aster: 1. Strong erect floweringstems. 2. Symmetrical branching habit. 3. Dark green-colored foliage. 4. Uniform and freely flowering habit. 5. Decorative-type inflorescences with violet-colored ray florets. 6. Good postproduction longevity.
Plants of the new Aster are taller than plants of the female parent selection. In addition, plants of the new Aster differ from plants of the female parent selection in ray floret coloration.
Plants of the new Aster can be compared to plants of the cultivar Cirina, not patented. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador plants of the new Aster differed from plants of the cultivar Cirina in the followingcharacteristics: 1. Plants of the new Aster were more vigorous than plants of the cultivar Cirina. 2. Plants of the new Aster had stronger flowering stems than plants of the cultivar Cirina. 3. Plants of the new Aster had larger and darker-greencolored leaves than plants of the cultivar Cirina. 4. Plants of the new Aster had larger inflorescences with more ray and disc florets per inflorescence than plants of the cultivar Cirina. 5. Inflorescences of plants of the new Aster had morephyllaries than inflorescences of plants of the cultivar Cirina. 6. Plants of the new Aster had longer peduncles than plants of the cultivar Cirina. 7. Plants of the new Aster and the cultivar Cirina differed in ray floret coloration as plants of thecultivar Cirina had purple violet-colored ray florets.
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 colorvalues cited in the detailed botanical description which accurately describe the colors of the new Aster.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Esmart`.
The photograph at the bottom of the sheet comprises a close-up view of a typical inflorescence of `Esmart`.
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, followingobservations and measurements describe plants grown and flowered during the summer in El Quinche, Pichincha, Ecuador, in an outdoor nursery and under conditions which approximate those generally used in commercial cut flower Aster production. During theproduction of these plants, day temperatures ranged from 12 to 30.degree. C. and night temperatures ranged from 5 to 12.degree. C. Plants were about four to six months from planting rooted young plants when the photographs and the botanical descriptionwere taken. Botanical classification: Aster hybrida cultivar Esmart.
