Spot form net blotch, caused by f. , is a significant necrotrophic disease of barley that spread worldwide in the twentieth century. Genetic relationships were analyzed to determine the diversity, survival, and dispersal of a diverse collection of 346 isolates from Australia, Southern Africa, North America, Asia Minor, and Europe.

Wild and landrace barley are underutilized, however, contain an abundance of loci that can be used as potential sources of resistance. Rhynchosporium commune, the causal agent of the disease scald or leaf blotch of barley, is a hemibiotrophic fungal pathogen of global importance, responsible for yield losses ranging from 30 to 40% on susceptible varieties.

Isolates of Ptm exhibit varying levels of aggressiveness that result in quantifiable changes in the severity of the disease.

- Unimproved landraces and wild relatives of crops, like wild barley, offer valuable genetic diversity lost during modern domestication and breeding, which can be harnessed through genome-wide association studies.
- These wild barley varieties have evolved alongside fungal pathogens that cause significant diseases, presenting an opportunity to discover new resistance traits due to their long-term co-evolution.
- The study identified 14 genetic loci related to resistance against two forms of the fungal pathogen in both wild and landrace barley, emphasizing the need for multiple analytical methods to uncover and confirm these resistance genes.
