Abstract
Because of the special demands on the German market a breeding programme was started in 1980 at Hohenheim University.
By shortening of the juvenility of the seedlings by good growing techniques and by regional tests of promising hybrids we could reduce the breeding time considerable.
This is a precondition for maintenance of fruit breeding.
The aims of breeding are especially a better combination of quality and quantity, the extension of ripening time and resistance to plum pox virus (sharka). For this aims always varieties with the special properties were taken, but due to the fact that plums are highly heterozygous it is difficult to predict the characteristics of the progenies.
In resistance breeding we got surprising good results with ‘Stanley’ as donator for sharka resistance.
For shortening the time to find sharka resistant new varieties, we look for markers in the leaves of the young seedlings.
Three new varieties, resulted from our breeding work, are described.
