Abstract
A new and distinct cultivar of Prunus plant named ‘Weiroot 720’, characterized by its upright plant habit; weak vegetative growth and low vigor; good soil adaptation; and as a rootstock, weak vegetative growth imparts uniformity, higher yield and larger fruit size to the scion plant.
Description
Botanical designation: Prunus cerasus.
Cultivar denomination: ‘WEIROOT 720’.
The present invention relates to a new and distinct cultivar of Prunus plant, typically used as a cherry tree rootstock, botanically known as Prunus cerasus, and hereinafter referred to by the name ‘Weiroot 720’.
The new Prunus plant is a naturally-occurring whole plant mutation of Prunus cerasus ‘Weiroot 72’, not patented. The new Prunus plant was discovered and selected by the Inventor from within a population of plants of ‘Weiroot 72’ in the autumn of 2001 in an outdoor nursery in Bavaria, Freising, Germany.
Asexual reproduction of the new Prunus plant by tissue culture since the autumn of 2001 in a controlled environment in Bavaria, Freising, Germany has shown that the unique features of this new Prunus plant are stable and reproduced true to type in successive generations.
Plants of the new Prunus have not been observed under all possible environmental conditions. 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 ‘Weiroot 720’. These characteristics in combination distinguish ‘Weiroot 720’ as a new and distinct cultivar of Prunus:
-
- 1. Upright plant habit.
- 2. Weak vegetative growth and low vigor.
- 3. Good soil adaptation.
- 4. As a rootstock, weak vegetative growth imparts uniformity, higher yield and larger fruit size to the scion plant.
Plants of the new Prunus plant differ primarily from plants of the parent, ‘Weiroot 72’, in the following characteristics:
-
- 1. Plants of the new Prunus root better than plants of ‘Weiroot 72’.
- 2. Plants of the new Prunus have weaker vegetative growth than plants of ‘Weiroot 72’.
- 3. Due to its weaker vegetative growth, plants of the new Prunus impart higher yield and larger fruit size to the scion plant than plants of ‘Weiroot 72’.
Plants of the new Prunus can be compared to plants of Prunus ‘Weiroot 158’, not patented. In side-by-side comparisons conducted in Bavaria, Freising, Germany, plants of the new Prunus differed primarily from plants of ‘Weiroot 158’ in the following characteristics:
-
- 1. Plants of the new Prunus had weaker vegetative growth than plants of ‘Weiroot 158’.
- 2. Due to its weaker vegetative growth, plants of the new Prunus imparted higher yield and larger fruit size to the scion plant than plants of ‘Weiroot 158’.
The accompanying photographs illustrate the overall appearance of the new Prunus plant. These photographs show 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 Prunus plant.
The photograph on the first sheet comprises a side perspective view of a typical tree of ‘Weiroot 720’ grown in an outdoor orchard.
The photograph on the second sheet comprises a close-up view of a typical tree of ‘Weiroot 720’ grown in an outdoor orchard.
The photograph on the third sheet is a close-up view of a typical flowering branch of ‘Weiroot 720’.
The aforementioned photographs, following observations and measurements describe plants grown during the summer in Nederweert, The Netherlands in an outdoor nursery and under conditions and practices generally used in commercial Prunus production. Plants were one year old when the photographs and description were taken. Measurements and numerical values represent averages for typical plants and plant parts. The actual measurements of any individual plant or plant parts, or any group of plants or plant parts, of the new Prunus plant may vary from the stated average. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
