Abstract
At Hohenheim we started a plum-breeding programme to get new sharka resistant cultivars with better fruit quality.
In the last years we have recognized that the resistance of all cultivated plums is based on quantitative criteria and therefore relative.
For this reason we changed our strategy for resistance breeding.
In the first breeding cycle we took special donors with quantitative resistance.
Today the qualitative type of resistance is more integrated.
We want to combine both types of resistance in the hexaploid genome of Prunus domestica to get an absolute and durable resistance.
For this to achieve we have to consider the evaluation of resistance, the genetic resources, the inheritance of resistance and also the breeding methods including genetic engineering.
The results of our resistance breeding are presented.
