In den Jahren 1974 und 1975 wurden bei 6 Sorten von Vitis vinifera an 10 Standorten Versuchsdaten gewonnen und daraus die Heritabilität im weiteren Sinn (Hw) berechnet. Die Werte für Hw liegen in einer Größenordnung, wie sie auch bei anderen Kulturpflanzen festgestellt worden ist. Für alle untersuchten Ertragskomponenten und für die vegetativen Merkmale wurden relativ hohe Hw-Werte gefunden. Eine Selektion auf diese Eigenschaften dürfte daher bei vegetativer Vermehrung von
- Pflanzen aus Sämlingspopulationen,
- Pflanzen aus Klonselektionen und
- Pflanzen aus Mutationsversuchen
trotz der Umwelteinflüsse erfolgreich sein.
Estimation of broad sense heritability of some characters of Vitis vinifera
In 1974 and 1975, investigation data were obtained from 6 Vitis vinifera cvs. grown at 10 locations and used to calculate the broad sense heritability (Hw). The values for Hw lie within the same range as those established for other cultivated plants. Relatively high Hw values were found for all investigated yield components and for the vegetative characters. Notwithstanding environmental influences, a selection with regard to these characters should thus be successful for vegetative propagation of
- plants from seedling populations,
- plants from clonal selection
- and plants from mutation trials.
