Powdery mildew on (grass pea) is commonly caused by , the causal agent of pea powdery mildew. could also pose an additional threat to grass pea, as it does to pea (). In order to understand the potential threat and the availability of resistance sources, the response to both pathogens was analyzed on a worldwide germplasm collection of 189 grass pea accessions.

- Grass pea, an annual legume related to common peas, can be infected by the Fusarium oxysporum pathogen, which causes significant yield losses in peas, with varying resistance observed among different grass pea plants.
- A genome-wide association study was conducted on grass pea accessions to identify genetic regions linked to resistance against fusarium wilt, using high-throughput SNP screening and mapping against the pea reference genome.
- The research identified 17 genomic regions associated with resistance traits, highlighting candidate genes involved in metabolism and development, which could aid in breeding disease-resistant grass pea varieties through molecular tools.
