Abstract

A new and distinct cultivar of Dahlia plant named ‘HGD-92-8’ characterized by its vigorous growth, compact plants and fast response. The flowers have contrasting colors between ray and disc florets.

Description

LATIN NAME OF THE GENUS AND SPECIE OF THE CLAIMED PLANT
Dahlia variabilis.
VARIETY DENOMINATION
‘HGD-92-8’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Dahlia variabilis known by the varietal denomination ‘HGH-92-8’. The female parent of ‘HGD-92-8’ is an unpatented selection from a proprietary breeding collection known as ‘DA-92’. The male parent is also an unpatented selection from the proprietary breeding collection known as ‘DA-92’.
The new cultivar ‘HGD-92-8’ is a product of a planned breeding program and was originated by selection of a progeny plant from the stated cross made on September, 1998 by the Inventor at HEM GENETICS, Hemmerbuurt 98, 1607 LC Hem, the Netherlands. ‘HGD-92-8’ was first asexually propagated on May 1, 1999 by the Inventor at HEM GENETICS, Hemmerbuurt 98, 1607 LC Hem, the Netherlands.
The new variety is a Dahlia plant useful for growing outdoors and under glass which produces attractive contrasting red and pink/white flowers. Among the traits possessed by the new variety which in combination distinguish it from other varieties known to the inventor are its attractive flowers with contrasting flower colors, vigorous growth, compact plants and fast response/early flowering.
Asexual reproduction by cuttings of the new variety in The Netherlands has demonstrated that the combination of characteristics as described herein for ‘HGD-92-8’ are firmly fixed and are retained through successive generations of asexual reproduction.
DESCRIPTION OF THE INVENTION
‘HGD-92-8’ is particularly characterized by the following:
1. Compact growing plants;
2. Fast flower responses;
3. Flower shape;
4. Vigorous growth;
5. Abundance of flowers; and
6. Contrasting red/white-pink flower color.
Perhaps the closest comparison cultivar is ‘Estivo’ (unpatented). ‘HGD-92-8’ is more compact and has a different flower color than ‘Estivo’. In comparison to the parental cultivar ‘DA-92’, ‘HGD-92-8’ is 10% shorter. ‘HGD -92-8’ has not been tested under all available environmental conditions and the phenotype may vary with variations in environmental conditions such as temperature, light intensity, day length and humidity, without a change in genotype of the plant.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic illustrations show typical characteristics of ‘HGD-92-8’.
Sheet 1 is a side view of plant.
Sheet 2 is a close up of a flower.
DETAILED BOTANICAL DESCRIPTION
The following observations, meassurements and values describe plants grown under commercial conditions. All color references are measured against The Royal Horticultural Society (R.H.S.)
