Definitions
- the present invention relates to a new and distinct cultivar of Aster plant, botanically known as Aster novi - belgii (now Symphyotrichum novi - belgii ) of the Asteraceae family, commonly known as Michaelmas Daisy and New York Aster, and hereinafter referred to by the cultivar name ‘DASJES’.
- the new Aster cultivar is a product of a planned breeding program conducted by the inventor, Bent Juhl JENSEN, in Malling, Denmark.
- the objective of the breeding program is to develop a new Aster variety with uniform plant growth habit, unique floret colors, and good postproduction longevity.
- the new Aster cultivar originated from a cross made in a controlled breeding program by the inventor on Apr. 1 2005, in Malling, Denmark.
- the female or seed parent is Aster novi - belgii ‘WHITE SWAN’ (unpatented).
- the male or pollen parent is Aster novi-belgii ‘WHITE PRESTIGE’ (unpatented, described in terminated CPVO Grant No. 8521).
- the new Aster ‘DASJES’ was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in September of 2006 in a controlled environment in Malling, Denmark.
- the selection of the new Aster ‘DASJES’ was based on its uniform plant growth habit and desirable inflorescence form and ray floret color.
- Plants of the new Aster ‘DASJES’ differ from plants of the parents, Aster novi - belgii ‘WHITE SWAN’ (unpatented) and Aster novi - belgii ‘WHITE PRESTIGE’ (unpatented, described in terminated CPVO Grant No. 8521), in the characteristics described below:
- Leaf Shape Gladiate to oblanceolate Lanceolate Capitulum Size: Diameter: 40 mm Diameter: 32.5 mm Ray Florets About 250 ray florets per About 150 ray florets per inflorescence, which are flower, which are oval in shape, with narrowly obovate in rounded, slightly retuse shape, with rounded apex apex Mature Ray Floret Pure White, whiter than Creamy white, RHS Color RHS 155D, and older 155D (upper surface): petals get a tinge of purple, RHS 75A Disc Florets: About 5 disc florets per About 25-35 disc florets inflorescence per inflorescence Mature Disc Floret Pure white, whiter Yellow-green, RHS Color: than RHS 155D, with 151B green margin, RHS 134
- FIG. 1 shows a side view perspective a typical flowering plant of ‘DASJES’ in a 9.5 cm pot, at 10 weeks of age after planting.
- FIG. 2 shows a close-up view perspective of a typical mature inflorescence of ‘DASJES’, at 10 weeks of age after planting.
- FIG. 3 shows a close-up comparison view of a typical mature inflorescence and leaf of: 1) the new Aster ‘DASJES’ (referenced by breeder designation 120-2), compared to 2) the comparison cultivar Aster ‘VICTORIA DIANA’ (referenced by DIANA), and 3) the male parental cultivar Aster ‘WHITE PRESTIGE’.
- the new Aster ‘DASJES’ has not been observed under all possible environmental conditions.
- the phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.
- ‘DASJES’ plants were grown in 9.5 cm pots in a heated and lighted glass-covered greenhouse with the day temperatures ranging from 18° C. to 20° C. and the night temperature averaging 18° C.
- ‘DASJES’ plants are grown under long day (20 hour) photoperiodic treatments for five weeks, followed by short day (12 hour) photoperiodic treatments for five weeks. During the long day (20 hour) photoperiodic treatments, if ambient light level falls below +50 Wm 2 , a supplementary light at +200 Wm 2 is applied.
- ‘DASJES’ plants ‘DASJES’ plants were pinched once, and treated twice with the growth retardant Daminozide.

Abstract
Description
-
- 1. Upright and inverted conical plant habit;
- 2. Green and gray-green foliage;
- 3. Decorative, composite-type inflorescence with about 250 white colored ray florets; and
- 4. Only about 5 disc florets per inflorescence which are white in color with green margin (almost 100% filled capitulae).
-
- 1. Plants of ‘DASJES’ are more compact than plants of both ‘WHITE SWAN’ and ‘WHITE PRESTIGE’;
- 2. Plants of ‘DASJES’ produce more ray florets than plants of both ‘WHITE SWAN’ and ‘WHITE PRESTIGE’; and
- 3. Plants of ‘DASJES’ produce purely white-colored ray florets whereas plants of ‘WHITE SWAN’ produce white-colored ray florets and plants of ‘WHITE PRESTIGE’ produce creamy white-colored ray florets.
