USPP23769P3 - Dahlia plant named ‘LOMDAHBRS’ - Google Patents

Abstract

A new and distinct Dahlia cultivar named ‘LOMDAHBRS’ is disclosed, characterized by distinctive strong red flowers, a compact plant with a floriferous habit, and free branching. The new variety is a Dahlia, normally produced as an outdoor ornamental plant for containers or gardens.

Description

Latin name of the genus and species: Dahlia hybrid.

Variety denomination: ‘LOMDAHBRS’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a result of a planned breeding program directed by the inventor, Henry Lommerse a citizen of the Netherlands. The parent is an undistributed, unpatented proprietary variety Dahlia hybrid ‘25079’ and the pollen parent is the undistributed, unpatented proprietary variety Dahlia hybrid ‘25075.’ The new variety was discovered as a seedling in June 2006, by the inventor in a commercial research greenhouse in Mariahout, the Netherlands.

Asexual reproduction of the new cultivar ‘LOMDAHBRS’ by vegetative cuttings was first performed in 2008, at a research greenhouse in Mariahout, the Netherlands. Multiple generations have since been produced and have shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘LOMDAHBRS’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘LOMDAHBRS’ These characteristics in combination distinguish ‘LOMDAHBRS’ as a new and distinct Dahlia cultivar:

• • 1. Sturdy plant with a compact habit
  • 2. Strong red flower color
  • 3. Good branching characteristics
  • 4. Floriferous habit.

PARENT COMPARISON

Plants of the new cultivar ‘LOMDAHBRS’ are similar to plants of the seed parent, Dahlia hybrid ‘25079’ in most horticultural characteristics, however, plants of the new cultivar ‘LOMDAHBRS’ produce more flowers, bloom for a longer period of time and produce more ray florets than ‘25079’. Additionally, plants of the parent variety are less sturdy and more open then ‘LOMDAHBRS.’

Plants of the new cultivar ‘LOMDAHBRS’ are similar to plants of the pollen parent, Dahlia hybrid ‘25075’ in most horticultural characteristics, however, plants of the new cultivar ‘LOMDAHBRS’ produce more flowers with a brighter red color, and foliage that is more resistant to damage.

COMMERCIAL COMPARISON

‘LOMDAHBRS’ can be compared to the commercial variety Dahlia hybrida ‘Singer’ U.S. Plant Pat. No. 11,315. The two varieties are similar in many horticultural characteristics, including having a similar flower color. However, plants of ‘LOMDAHBRS’ differ in producing more branches, and a more compact plant shape than ‘Singer.’ Additionally plants of ‘LOMDAHBRS’ begin flowering earlier from a rooted cutting than ‘Singer.’ Flower form is also different between the two varieties, with ‘LOMDAHBRS’ producing a more spherical, less flattened flower form.

The new variety can also be compared to the commercial variety unpatented Dahlia variabilis, ‘Dapared’. U.S. Plant Pat. No. 17,143. Dahlia ‘LOMDAHBRS’ and Dahlia ‘Dapared’ are similar in many horticultural characteristics, including a similar flower color. However, plants of ‘LOMDAHBRS’ are more vigorous, produce more flowers and branches per plant, and larger flowers than ‘Dapared.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘LOMDAHBRS’ grown in a outdoors, in Mariahout, the Netherlands, in a commercial 20 cm container.

Age of the plant photographed is approximately 70 days from a rooted cutting. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
