ABSTRACT:
Botanical classification/cultivar designation:
Dahlia hybrida
cultivar Karma Ventura.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as
Dahlia hybrida
and hereinafter referred to by the name ‘Karma Ventura’.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Lisse, The Netherlands. The objective of the breeding program is to create new cut flower Dahlia cultivars with straight strong flowering stems, decorative inflorescence form, attractive ray floret colors, and good inflorescence longevity.
The new Dahlia originated from a cross-pollination made by the Inventor during the summer of 1996 of two unidentified selections of
Dahlia hybrida,
not patented. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Lisse, The Netherlands, in August, 1997. The selection of this plant was based on its strong straight stems and attractive ray floret coloration.
Asexual reproduction of the new Dahlia by cuttings was first conducted in a controlled environment in Lisse, The Netherlands in the Spring of 1998. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Karma Ventura 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Karma Ventura’. These characteristics in combination distinguish ‘Karma Ventura’ as a new and distinct Dahlia cultivar:
1. Straight and strong flowering stems.
2. Freely basal branching growth habit.
3. Decorative-type inflorescence form.
4. Bright yellow-colored ray florets.
5. Excellent garden performance.
6. Excellent inflorescence longevity.
Plants of the new Dahlia differ primarily from plants of the parent selections in ray floret coloration.
Plants of the new Dahlia can be compared to plants of the cultivar Glory of Heemstede, not patented. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Glory of Heemstede in the following characteristics:
1. Plants of the new Dahlia were more freely branching than plants of the cultivar Glory of Heemstede.
2. Inflorescences of plants of the new Dahlia had more ray florets than inflorescences of plants of the cultivar Glory of Heemstede.
3. Ray floret coloration of plants of the new Dahlia was darker yellow than ray floret coloration of plants of the cultivar Glory of Heemstede.
