Fig. 1. Partial molecular maps of barley chromosome 3H showing the genetic location of leaf rust resistance gene Rph5. Markers were mapped in two segregating populations: (A) Bowman (rph5) x Magnif 102 (Rph5); (B) Moore (rph5) x Virginia 92-42-46 (Rph5), respectively. Map distances are given in centimorgans (cM).

Fig. 3. Estimation of the relative locations of Rph5 and Rph7 leaf rust resistance genes on the basis of comparison of three maps with common markers. Maps of Moore x Virginia 92-42-46 and Bowman x Magnif 102 are from this study, and Cebada Capa x Bowman map was published recently (Brunner et al., 2000).
