Abstract

A new and distinct Calibrachoa cultivar named ‘DCALBUBGM’ is disclosed, characterized by a semi-trailing plant habit. Plants produce an abundance of large pink colored flowers with a yellow center and throat. Plants begin flowering early, have strong branches and are day length neutral. The new variety is a Calibrachoa, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Calibrachoa hybrid.

Variety denomination: ‘DCALBUBGM’.

BACKGROUND OF THE INVENTION

The new Calibrachoa cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Calibrachoa varieties. The cross resulting in this new variety was made during January of 2014.

The seed parent is the unpatented, propriety variety referred to as Calibrachoa ‘cv. 14-4051’. The pollen parent is the unpatented, propriety variety referred to as Calibrachoa ‘cv. 14-4050’. The new variety was discovered in March of 2015 by the inventor in a group of seedlings resulting from the parental crossing, in a greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DCALBUBGM’ was first performed by terminal vegetative cuttings during March of 2015, at a greenhouse in Moshav Mishmar Hashiva, Israel. Subsequent propagation by has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations. First public access to plants of the variety occurred Nov. 12, 2017 in the United States. This offer came directly or indirectly from the inventor, qualifying for the exception allowed under 102(b). Previous to this sale, although the variety may have been publicized in print, plants were not available to the public for propagation.

SUMMARY OF THE INVENTION

The cultivar ‘DCALBUBGM’ 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 ‘DCALBUBGM’ These characteristics in combination distinguish ‘DCALBUBGM’ as a new and distinct Calibrachoa cultivar:

- 1. Large pink flowers with a yellow throat.
- 2. Early flowering.
- 3. Flowering can begin under 10-hour day length, day-length neutral for this market class.
- 4. Semi-trailing plant habit.
- 5. Medium vigor.

PARENT COMPARISON

Plants of the new cultivar ‘DCALBUBGM’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘DCALBUBGM’ differ in the following;

- 1. The new variety has a semi-trailing growth habit; the seed parent is compact, mounding.
- 2. New variety has pink flowers; seed parent has white flowers.
- 3. The new variety has larger flowers than the seed parent.
- 4. The seed parent has a lower vigor than the new variety.

Plants of the new cultivar ‘DCALBUBGM’ are similar to plants of the pollen parent in most horticultural characteristics however, plants of the new cultivar ‘DCALBUBGM’ differ in the following;

- 1. The new variety has a semi-trailing growth habit; the pollen parent is compact.
- 2. The new variety has pink flowers; the pollen parent has white flowers with pink eyes.
- 3. The new variety has larger flowers than the pollen parent.
- 4. The pollen parent has a lower vigor than the new variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCALBUBGM’ can be compared to the patented commercial variety Calibrachoa ‘DANOA49’ U.S. Plant Pat. No. 22,050. These varieties are similar in most horticultural characteristics; however, ‘DCALBUBGM’ differs in the following:

- 1. ‘DCALBUBGM’ is earlier to flower in comparison to ‘DANOA49’.
- 2. ‘DCALBUBGM’ is day length neutral, while ‘DANOA49’ is not.
- 3. ‘DCALBUBGM’ has a bigger flower than ‘DANOA49’.
- 4. ‘DCALBUBGM’ has a semi-trailing habit, while ‘DANOA49’ is trailing.

Plants of the new cultivar ‘DCALBUBGM’ can also be compared to the commercial variety Calibrachoa ‘Duealtihotpi’, U.S. Plant Pat. No. 21,502. These varieties are similar in most horticultural characteristics; however, ‘DCALBUBGM’ differs in the following:

- 1. ‘DCALBUBGM’ is day length neutral; ‘Duealtihotpi’ is not.
- 2. ‘DCALBUBGM’ has a more vivid pink color than ‘Duealtihotpi’.
- 3. ‘DCALBUBGM’ has a semi-trailing habit, while ‘Duealtihotpi’ is trailing.
- 4. ‘DCALBUBGM’ is more vigorous than ‘Duealtihotpi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant in a 20 cm pot, at approximately 5 months of age, of ‘DCALBUBGM’ grown in a greenhouse, in Moshav Mishmar Hashiva, Israel.

FIG. 2 illustrates in full color typical flowering plants of ‘DCALBUBGM’ grown in 12 cm pots in early Spring, during days having 10 hours of light.

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
