Barley yellow mosaic disease is present in all European countries now. In Germany where extensive yield losses are observed frequently the disease is caused by a complex of three viruses, i.e. BaYMV, BaMMV and a 'new virus strain'. Resistance of German winter barley cultivars, which is not effective against the 'new virus strain', is inherited by a single recessive gene located on chromosome 3. Foreign varieties carrying different resistance genes were identified, some of them are even effective against the 'new virus strain'. Because of inferior agronomic performance of these exotic resistant germplasms, efficient breeding procedures are needed. In particular, the application of androgenetic doubled haploids in combination with marker based selection schemes is considered to be a very useful tool for the rapid incorporation of these alien resistance genes into adapted varieties
