Description	Data on the distribution of some wind-dispersed nomadic plant diseases (cereal powdery mildews, leaf rust of wheat) suggest that virulence genes accumulate in the direction of prevailing wind dispersal, through the interaction of migration and selection.E.g., for leaf rust of wheat virulence complexity increased from 2-4 on average in France to approximately 7 in Austria and Poland up to 14 and above in Siberia. This situation can be of considerable importance for the use of host resistance. The higheris the virulence in a pathogen population, the more valuable for resistance breeding should be the effective resistance genes present in that area. If virulence complexity increases in the direction of predominant dispersal, the number of unnecessary virulence genes increases as well. The time of efficient use of resistance genes is thought to be prolonged if the area of host culture would shift against the direction of predominant dispersal.
