Gene stops barley leaf rust

Researchers have discovered the gene Rph20 provides resistance to leaf rust in some barley variety adult plants.

Leaf rust is a fungal disease that could destroy almost a third of the nation’s barley crop.

In North Africa and Southwest Asia barley is a staple food. In Australia it is primarily used to make beer and stock feed.

The discovery will enable selective breeding of barley that will provide genetic protection to the disease, resulting in lower chemical use, reduced crop losses, and a more reliable grain supply.
