Abstract
A new and distinct Primula plant named ‘IFPROB’, characterized by its compact and upright plant habit; moderately vigorous to vigorous growth habit and moderate growth rate; dense basal rosettes of leaves with inflorescences held above the foliar plane; freely flowering habit; violet-colored flowers with bright yellow-colored centers; and good garden performance.
Description
Botanical designation: Primula vulgaris.
Cultivar denomination: ‘IFPROB’.
The present invention relates to a new and distinct cultivar of Primula plant, botanically known as Primula vulgaris, commonly referred to as Primrose and hereinafter referred to by the name ‘IFPROB’.
The new Primula plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to create new compact and uniformly mounding Primula plants with numerous attractive flowers and good garden performance.
The new Primula plant originated from a cross-pollination made by the Inventor in April, 2017 in Heerhugowaard, The Netherlands of a proprietary selection of Primula vulgaris identified as code number 13-58-02, not patented, as the female or seed parent, with a proprietary selection of Primula vulgaris identified as code number 12-13-01, not patented, as the male or pollen parent. The new Primula plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heerhugowaard, The Netherlands in April, 2018.
Asexual reproduction of the new Primula plant by in vitro meristem culture in a controlled greenhouse environment in Heerhugowaard, The Netherlands since June, 2019 has shown that the unique features of this new Primula plant are stable and reproduced true to type in successive generations.
Plants of the new Primula have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘IFPROB’. These characteristics in combination distinguish ‘IFPROB’ as a new and distinct Primula plant:
-
- 1. Compact and upright plant habit.
- 2. Moderately vigorous to vigorous growth habit and moderate growth rate.
- 3. Dense basal rosettes of leaves with inflorescences held above the foliar plane.
- 4. Freely flowering habit.
- 5. Violet-colored flowers with bright yellow-colored centers.
- 6. Good garden performance.
Plants of the new Primula can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Primula differ primarily from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Primula are more compact than plants of the female parent selection.
- 2. Plants of the new Primula have smaller flowers than plants of the female parent selection.
Plants of the new Primula can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Primula differ primarily from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Primula have larger flowers than plants of the male parent selection.
- 2. Flowers of plants of the new Primula are violet and bright yellow in color whereas flowers of plants of the male parent selection are red and yellow in color.
Plants of the new Primula can be compared to plants of Primula vulgaris ‘Oakleaf Yellow’, not patented. In side-by-side comparisons, plants of the new Primula differ primarily from plants of ‘Oakleaf Yellow’ in the following characteristics:
-
- 1. Plants of the new Primula are more compact than plants of ‘Oakleaf Yellow’.
- 2. Plants of the new Primula flower for a shorter period of time than plants of ‘Oakleaf Yellow’.
- 3. Plants of the new Primula have smaller flowers than plants of ‘Oakleaf Yellow’.
- 4. Flowers of plants of the new Primula are violet and bright yellow in color whereas flowers of plants of ‘Oakleaf Yellow’ are red and yellow in color.
The accompanying colored photographs illustrate the overall appearance of the new Primula plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Primula plant.
The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘IFPROB’ grown in a container.
The photograph at the top of the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘IFPROB’.
The photograph at the bottom of the second sheet (FIG. 3 ) is a close-up view of typical leaves of ‘IFPROB’.
The aforementioned photographs and following observations and measurements describe plants grown during the spring in 1.5-liter containers in an outdoor nursery in Heerhugowaard, The Netherlands and under cultural practices typical of commercial Primula production. During the production of the plants, day temperatures ranged from 10° C. to 20° C. and night temperatures ranged from 10° C. to 13° C. Plants were 18 weeks from planting when the photographs and description were taken.
