Genetic Hybridization Global Food Security Agricultural Biotechnology

Researchers from China have identified a new genetic locus in the weed Elymus repens that provides resistance to Fusarium Head Blight (FHB). By hybridizing this weed with cultivated wheat, they successfully transferred the resistance, reducing diseased spikelets by 60-69% in tests.
