Abstract

The barley yellow mosaic virus complex consists of barley mild mosaic (BaMMV), barley yellow mosaic virus type 1 (BaYMV-1) and barley yellow mosaic virus type 2 (BaYMV-2). In an attempt to investigate the genetic basis of resistance to these pathogens, a series of genes, including 3 novel previously undescribed ones, have been identified in cultivated barley (Hordeum vulgare). They vary in their specificity for individual members of this virus complex and were localized within the barley genome using a set of mapped RFLP markers. Along with previously characterized resistance genes, 9 different genes have now been described in barley. These form 2 major complexes on the long arms of chromosomes 3 and 4 consisting of 4 and 3 loci, respectively.
