Description

LATIN NAME OF THE GENUS AND SPECIE OF THE PLANT CLAIMED
Dahlia variabilis.
VARIETY DENOMINATION
‘HGD-161-7’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Dahlia variabilis known by the varietal denomination ‘HGD-161-7’. The female parent of ‘HGD-161-7’ is an unpatented selection from a proprietary breeding collection known as ‘DA-93’. The male parent is also an unpatented selection from the proprietary breeding collection known as ‘DA-93’.
The new cultivar ‘HGD-161-7’ is a product of a planned breeding program and was selected from the progeny of the stated cross made on September, 1998 by the Inventor at HEM GENETICS, Hemmerbuurt 98, 1607 LC Hem, the Netherlands, ‘HGD-161-7’ was first asexually progated 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 yellow-orange 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 chaacteristics as described herein for ‘HGD-161-7’ are firmly fixed and are retained through successive generations of asexual reproduction.
BRIEF DESCRIPTION OF THE INVENTION
‘HGD-161-7’ is particularly characterized by the following:
1. Compact growing plants;
2. Fast flower responses;
3. Vigorous growth;
4. Abundnace of flowers;
5. Shape of the flowers; and
6. Contrasting red/yellow-orange flower color.
Perhaps the closest comparision cultivar is ‘Estivo’ (unpatented). ‘HGD-161-7’ is more compact and has a different flower color than ‘Estivo’. In comparision to the parental cultivar ‘DA-93’, the flower color of ‘HGD-161-7’ is red, RHS 46A and yellow, and the flower color of ‘DA-93’ is deep red, RHS 53A and yellow. ‘HGD-161-7’ 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 color photographic drawings show typical characteristics of ‘HGD-161-7’.
Sheet 1 is a top view of a plant.
Sheet 2 is a close up of a flower.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe plants grown under commercial conditions. All color references are measured against The Royal Horticultural Society (R.H.S.) Colour Chart (1995 edition). Colors are approximate as color depends on horticultural practices such as light level and treatment rate, among others, without however any variance in genotype.
