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).
