Abstract
A new and distinct cultivar of Photinia plant named ‘Kolmavoca’, characterized by its upright and outwardly spreading plant habit; relatively short internodes; glossy dark purplish brown-colored young leaves that become dark green with development; leaves with serrated and undulating margins; and tolerance to Powdery Mildew.
Description
Botanical designation: Photinia×fraseri×Photinia Serratifolia.
Cultivar denomination: ‘KOLMAVOCA’.
The present invention relates to a new and distinct cultivar of Photinia plant, botanically known as Photinia×fraseri×Photinia serratifolia and hereinafter referred to by the name ‘Kolmavoca’.
The new Photinia plant is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program is to create new Photinia plants with intense red-colored developing leaves and tolerance to Powdery Mildew.
The new Photinia plant originated from a cross-pollination conducted by the Inventor in June, 2006 in Boskoop, The Netherlands of Photinia×fraseri ‘Red Robin’, not patented, as the female, or seed parent with an unidentified proprietary selection of Photinia serratifolia, not patented, as the male, or pollen, parent. The new Photinia plant was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Boskoop, The Netherlands in June, 2009.
Asexual reproduction of the new Photinia plant by vegetative cuttings in a controlled greenhouse environment in Boskoop, The Netherlands since June, 2009 has shown that the unique features of this new Photinia plant are stable and reproduced true to type in successive generations.
Plants of the new Photinia have not been observed under all possible 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 ‘Kolmavoca’. These characteristics in combination distinguish ‘Kolmavoca’ as a new and distinct Photinia plant:
-
- 1. Upright and outwardly spreading plant habit.
- 2. Relatively short internodes.
- 3. Glossy dark purplish brown-colored young leaves that become dark green with development.
- 4. Leaves with serrated and undulating margins.
- 5. Tolerance to Powdery Mildew.
Plants of the new Photinia differ primarily from plants of the female parent, ‘Red Robin’, in the following characteristics:
-
- 1. Leaves of plants of the new Photinia are smaller and darker in color than leaves of plants of ‘Red Robin’.
- 2. Leaf margins of plants of the new Photinia are serrated and undulating whereas leaf margins of plants of ‘Red Robin’ are entire and non-undulating.
- 3. Plants of the new Photinia are more tolerant to Powdery
Mildew than plants of ‘Red Robin’.
Plants of the new Photinia differ primarily from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Photinia are more compact and have shorter internodes than plants of the male parent selection.
- 2. Plants of the new Photinia have smaller leaves than plants of the male parent selection.
Plants of the new Photinia can be compared to plants of Photinia hybrida ‘Kolcurl’, disclosed in U.S. Plant Pat. No. 13,584. In side-by-side comparisons, plants of the new Photinia differed primarily from plants of ‘Kolcurl’ in the following characteristics:
-
- 1. Plants of the new Photinia had shorter internodes than plants of ‘Kolcurl’.
- 2. Plants of the new Photinia had smaller leaves than plants of ‘Kolcurl’.
- 3. Leaves of plants of the new Photinia were darker in color than leaves of plants of ‘Kolcurl’.
The accompanying colored photographs illustrate the unique appearance of the new Photinia 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 from the color value cited in the detailed botanical description which accurately describe the colors of the new Photinia plant.
The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Kolmavoca’ grown in a container.
The photograph on the second sheet is a close-up view of developing leaves of ‘Kolmavoca’.
The photograph on the third is a close-up view of the upper surface of a typical fully expanded leaf of ‘Kolmavoca’.
Plants used in the aforementioned photographs and in the following description were grown during the summer and early autumn in three-liter containers in an outdoor nursery in Boskoop, The Netherlands and under cultural conditions which closely approximate commercial Photinia production. During the production of the plants, day temperatures ranged from 16° C. to 32° C. and night temperatures ranged from 8° C. to 18° C. Plants of the new Photinia were 15 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
