Fig. 6. Locations of resistance genes and common microsatellite markers redrawn from different genetic maps of the distal region of wheat chromosome 3BS. The stem rust resistance gene Sr2 (A) was mapped by Spielmeyer et al. (2003). A major QTL for resistance to Fusarium head scab (Qfhs) was mapped by (B) Liu and Anderson (2003) and (C) Buerstmayr et al. (2003). The Septoria tritici blotch resistance gene Stb2 (D) was mapped in the present study. Genetic distances in cM are indicated to the left of the respective maps for those studies in which they were reported. Approximate locations of the Lr27 gene for resistance to leaf rust and a gene for phenylalanine ammonia lyase (PAL) from Faris et al. (1999), plus a major QTL for resistance to Stagonospora nodorum glume blotch (QSng) from Schnurbusch et al. (2003)(personal communication), are indicated on the far right. Common markers in different maps are joined by dashed lines.
