Abstract
A new Dahlia plant named ‘DAHZ0001’, particularly distinguished by the large yellow double-type flowers, full and compact plant habit with excellent branching, medium green foliage, and good floriferiousness.
Description
Latin name of the genus and species of the plant claimed: Dahlia hybrid Cay.
Varietal denomination: ‘DAHZ0001’.
The present invention comprises a new Dahlia, botanically known as Dahlia hybrid and hereinafter referred to by the variety name ‘DAHZ0001’.
‘DAHZ0001’ is a product of a planned breeding program. The new cultivar ‘DAHZ0001’ has large yellow double-type flowers, full and compact plant habit with excellent branching, medium green foliage, and good floriferousness.
‘DAHZ0001’ originates from a sibling cross hybridization in a controlled breeding program in Andijk, Netherlands. The pollinations were made in August 2007.
The female parent was an unpatented, proprietary hybrid seedling identified as ‘DO6-262-1’, having pink color, larger flowers and a smaller plant size than ‘DAHZ0001’.
The male parent of ‘DAHZ0001’ was an unpatented, proprietary plant identified as ‘DO6-265-1’, with yellow flower, smaller flower size, smaller leaves, and more freely branching plant habit than ‘DAHZ0001’.
The resulting the seed sown in November 2007, and ‘DAHZ0001’ was selected as one flowering plant within the progeny of the stated cross in February 2008 in a greenhouse in Andijk, Netherlands.
The first act of asexual reproduction of ‘DAHZ0001’ was accomplished when vegetative cuttings were propagated from the initial selection in March 2008 in a controlled environment in Andijk, Netherlands.
Horticultural examination of plants grown from cuttings of the plant initiated in April 2008 in Andijk, Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘DAHZ0001’ are firmly fixed and are retained through successive generations of asexual reproduction.
‘DAHZ0001’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.
A Plant Breeder's Right for this cultivar was applied for in the European Community Plant Variety Office (CPVO) on Apr. 22, 2014, No. 2014/1052. ‘DAHZ0001’ has not been made publicly available more than one year prior to the filing of this application.
The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Dahlia as a new and distinct variety.
The accompanying photographic drawings show typical flower and foliage characteristics of ‘DAHZ0001’ with colors being as true as possible with an illustration of this type. The photographic drawings show in FIG. 1 a close-up of the flowers and FIG. 2 a flowering potted plant of the new variety.
The plant descriptions and measurements were taken in Enkhuizen, The Netherlands, on the 4th of September, from 14 week old plants that were growing outdoors in the trial field.
The aforementioned photographs were taken at the same time in April 2012 in Andijk, Netherlands. The potted plants were growing on benches in a greenhouse. They were about 12 weeks of age.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
