Based on the RAPD marker OP‐C04H910 which is closely linked to the barley mild mosaic virus (BaMMV) resistance gene rym9 derived from the variety ‘Bulgarian 347’ the marker STS‐C04H910 cosegregating with OP‐C04H910 and generating a single additional band on plants carrying the recessive resistance encoding allele has been developed. Furthermore, the simple sequence repeats (SSRs) WMS6 and HVM67 have been integrated into the genetic map of the rym9 region on chromosome 4HL. Because of their close linkage to rym9 and distinct banding pattern STS‐C04H910 and HVM67 are well‐suited for marker‐ assisted selection, enhanced backcrossing procedures and pyramiding of resistance genes.
