Characterization of Leaf Rust Resistance in International Barley Germplasm Using Genome-Wide Association Studies.

A panel of 114 genetically diverse barley lines were assessed in the greenhouse and field for resistance to the pathogen , the causal agent of barley leaf rust. Multi-pathotype tests revealed that 16.6% of the lines carried the all-stage resistance (ASR) gene , followed by (4.

Characterization of Rph24: A Gene Conferring Adult Plant Resistance to Puccinia hordei in Barley.

We identified Rph24 as a locus in barley (Hordeum vulgare L.) controlling adult plant resistance (APR) to leaf rust, caused by Puccinia hordei. The locus was previously reported as a quantitative trait locus in barley line ND24260-1 and named qRphND.
