Abstract
A distinct cultivar of potted Aster plant named ‘M.C. Snowy’, characterized by its medium plant height at flowering; freely and uniform flowering; decorative inflorescence form with white ray florets; and good post-production longevity.
Description
The present invention relates to a new and distinct cultivar of Aster plant, botanically known and Aster novi-belgii and referred to by the cultivar name M.C. Snowy.
The new Aster is a product of a planned breeding program conducted by the Inventor in Ter Aar, The Netherlands. The objective of the breeding program was to create new cut flower Asters having desirable floret colors, uniform flowering and numerous inflorescences.
The new Aster originated from a cross made in 1995 by the Inventor of a Aster novi-belgii unidentified proprietary Aster selection as the female, or seed, parent with the Inventor's proprietary selection code No. MC 206 as the male, or pollen, parent.
The cultivar M.C. Snowy was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Ter Aar, The Netherlands.
Asexual reproduction of the new Aster by terminal cuttings taken at Ter Aar, The Netherlands, has shown that the unique features of this new Aster are stable and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unqiue characteristics of ‘M.C. Snowy’. These characteristics in combination distinguish ‘M.C. Snowy’ as a new and distinct cultivar:
1. Freely and uniform flowering.
2. Decorative inflorescence form with white ray florets.
3. Good post-production longevity.
Plants of the new Aster can be compared to plants of the Aster cultivar Peter's White, disclosed in U.S. Plant Pat. No. 10,783. In side-by-side comparisons conducted in Ter Aar, The Netherlands, plants of the new Aster differed from plants of the cultivar Peter's White in the following characteristics:
1. Plants of the new Aster are slightly taller than plants of the cultivar Peter's White.
2. Leaves of the new Aster are shorter and more narrow than leaves of the cultivar Peter's White.
3. Plants of the new Aster have smaller but more numerous inflorescences than plants of the cultivar Peter's White.
4. Inflorescences of the new Aster develop disc florets whereas inflorescences of plants of Peter's White do not develop disc florets.
The cultivar M.C. Snowy 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 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 slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Aster.
The photograph on the first sheet comprises a side perspective view of typical flowering stem of the new Aster.
The photograph on the second sheet comprises a close-up view of typical inflorescences of the new Aster.
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 during the summer in Ter Aar, The Netherlands, in a glass-covered greenhouse with average day temperatures of 17 to 35° C. and night temperatures of 14 to 20° C. Plants received long day/short night treatments 18 hours light for seven weeks and then were forced into flower with short day/long night treatments 12 hours light.
