Molecular mapping as a tool for pre-emptive breeding for resistance to the exotic barley pathogen, Puccinia striiformis f. sp. hordei
Barley stripe rust (BSR), caused by Puccinia striiformis f. sp. hordei, has been a major disease problem to the barley industry worldwide that has not, to date, been detected in Australia. This paper describes the mapping of stripe rust resistance genes in Tallon/Kaputar (TK) and Arapiles/Franklin (...
