Abstract

A genetic linkage map consisting of 211 molecular markers has been generated using a doubled-haploid population derived from a cross between the Australian barley variety Clipper and the Algerian landrace Sahara 3771. The map was used in subsequent trait mapping studies to locate the genes conferring boron tolerance and cereal cyst nematode resistance from Sahara 3371 and to map several plant type and developmental genes. Closely linked markers to the trait loci have been identified and are now being widely implemented in Australian breeding programs.

Keywords: barley linkage map, Clipper, Sahara, boron toxicity, CCN, SSR, RFLP.
