Puccinia hordei
provided by wikipedia EN
Puccinia hordei is a species of rust fungus. A plant pathogen, it can cause leaf rust of barley, also known as brown rust of barley.[2][3]
At the time of Johnston et al., 2013's discovery of severe susceptibility in Golden Promise, this was considered to be the most susceptible variety in the world.[3] Soon thereafter however, Yeo et al., 2014 found SusPtrit was slightly worse.[3] These results alter the meaning of such a basic term as "fully susceptible" to brown rust.[3]
