AFLP (amplified fragment length polymorphism), SSR (simple sequence repeat)<br />

<strong>and</strong> RGAP (resistance gene analog polymorphism) techniques.<br />

There are two nomenclature systems for <strong>barley</strong> chromosomes. Our merg<strong>in</strong>g<br />

of previous maps published by FRANCKOWIAK (1997), JENSEN (2002)<br />

<strong>and</strong> KLEINHOFS (2002), <strong>and</strong> the map available on the Barley Genomics page<br />

of Wash<strong>in</strong>gton State University (http://<strong>barley</strong>genomics.wsu.eu/arnis/l<strong>in</strong>kage_maps/<br />

maps-svg.html) resulted <strong>in</strong> a consensus map of <strong>barley</strong> disease resistance<br />

<strong>genes</strong> (Figure 1). This map was supplemented with resistance <strong>genes</strong> Rgd2a,<br />

Rrs2, Rpt4 <strong>and</strong> Rpt3 (WILLIAMS et al. 1999, MOLNAR et al. 2000, SCHWEIZER et<br />

al. 2000, TACCONI et al. 2001).<br />
