摘要：

The barley mosaic virus complex has become one of the major pathogens of cultivated winter barley in central Europe. One resistance gene (ym4) mediates complete immunity against barley mild mosaic virus (BaMMV) and barley yellow mosaic virus type 1 (BaYMV-1). An attempt is made to molecularly characterize the ym4 resistance locus on the long arm of barley chromosome 3 by means of RFLP and sequence-tagged-site (STS) markers. Two closely linked molecular markers have been identified which are suitable for marker-assisted selection for the resistance gene. A high resolution mapping population is being developed in order to provide the basis for positional cloning of the ym4 resistance gene.
