ABSTRACT:
Botanical classification/cultivar designation:
Dahlia variabilis
cultivar Balnovburs.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Dahlia
plant, botanically known as
Dahlia variabilis
, commercially referred to as a pot-type
Dahlia
, and hereinafter referred to by the cultivar name ‘Balnovburs’.
The new
Dahlia
is a product of a planned breeding program conducted by the Inventor in Enkhuizen, The Netherlands. The new
Dahlia
originated from a cross-pollination made by the Inventor in 1997 of two unidentified proprietary selections of
Dahlia variabilis
, not patented. The cultivar Balnovburs was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Enkhuizen, The Netherlands in October, 1997.
Asexual reproduction of the new
Dahlia
by stem cuttings was first conducted in Enkhuizen, The Netherlands in 1999. 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 Balnovburs has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and daylength, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balnovburs’. These characteristics in combination distinguish ‘Balnovburs’ as a new and distinct pot-type
Dahlia:
1. Upright plant habit.
2. Freely branching habit.
3. Semi-double type inflorescences.
4. Yellow and red-colored ray florets.
Plants of the new
Dahlia
differ from plants of the parent selections primarily in ray floret coloration as plants of the parent selections do not have yellow and red-colored ray florets.
Plants of the new
Dahlia
can be compared to plants of the
Dahlia
cultivar Balnovches, disclosed in U.S. Plant Pat. No. 14,254. In side-by-side comparisons conducted in West Chicago, Ill., plants of the new
Dahlia
were larger, more vigorous and had fewer ray florets per inflorescence than plants of the cultivar Balnovches. In addition, plants of the new
Dahlia
and the cultivar Balnovches differed in ray floret coloration.
