Clonal selection has been widely adopted for the improvement of wine grapes in Europe.
Positive results both for yield and for other fruit characters have been reported. On the other hand it was concluded from a large experiment with Muscat of Alexandria that no improvement could be expected from selection based on yield only without any other distinguishing character, a view which has been reiterated.
The present experiment was undertaken to test whether such differences in yield between sultana vines, which are grown in Australia on their own roots, were reproducible by vegetative propagation.
