BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis X Begonia tuberhybrida, commercially referred to as a Hybrid Begonia and hereinafter referred to by the name ‘Dobeciupblu’.
The new Begonia plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program was to develop new freely flowering Begonia plants with strong branches and attractive flowers.
The new Begonia plant originated from a cross-pollination made by the Inventor during the autumn of 2018 of a proprietary selection of Begonia x boliviensis X Begonia tuberhybrida identified as code number BG16-000027-001, not patented, as the female, or seed, parent with a proprietary selection of Begonia x boliviensis X Begonia tuberhybrida identified as code number BG16-000035-001, not patented, as the male or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands during the spring of 2019.
Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in De Lier, The Netherlands since the autumn of 2019 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘Dobeciupblu’. These characteristics in combination distinguish ‘Dobeciupblu’ as a new and distinct Begonia plant:
- 1. Relatively compact, semi-upright and mounded plant habit.
- 2. Moderately vigorous growth habit and moderate growth rate.
- 3. Strong branching habit.
- 4. Dark greenish brown-colored leaves.
- 5. Freely and continuously flowering habit.
- 6. Medium-sized double-type flowers with petals that are pale yellow in color with dark pink-colored edges and petaloids that are light yellowish pink in color.
Plants of the new Begonia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:
- 1. Plants of the new Begonia are more freely branching than plants of the female parent selection.
- 2. Flowers of plants of the new Begonia have pale yellow-colored petals with dark pink-colored edges and yellowish pink-colored petaloids whereas flowers of plants of the female parent selection are orange in color.
- 3. Plants of the new Begonia have shorter flower pedicels than plants of the female parent selection.
Plants of the new Begonia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of the male parent selection in flower color as plants of the new Begonia have flower petals that are pale yellow in color with dark pink-colored edges and petaloids that are light yellowish pink in color whereas flowers of plants of the male parent selection are orangish pink in color.
Plants of the new Begonia can be compared to plants of Begonia boliviensis X Begonia tuberhybrida ‘I'CONIA Bacio Peach’, not patented. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of ‘I'CONIA Bacio Peach’ in the following characteristics:
- 1. Plants of the new Begonia are more freely branching than plants of ‘I'CONIA Bacio Peach’.
- 2. Plants of the new Begonia have larger leaves than plants of ‘I'CONIA Bacio Peach’.
- 3. Plants of the new Begonia are more freely flowering than plants of ‘I'CONIA Bacio Peach’.
- 4. Flowers of plants of the new Begonia have more petaloids than flowers of plants of ‘I'CONIA Bacio Peach’.
- 5. Flowers of plants of the new Begonia have pale yellow-colored petals with dark pink-colored edges and yellowish pink-colored petaloids whereas flowers of plants of ‘I'CONIA Bacio Peach’ are soft yellow to peach in color.
- 6. Plants of the new Begonia have shorter flower pedicels than plants of ‘I'CONIA Bacio Peach’.
