AI Technical Summary
Current technologies for breeding wheat resistance to Fusarium head blight rely on a very small number of resistance genes, which are insufficient to effectively reduce the damage in years when Fusarium head blight is prevalent. There is a lack of stable resistance genes and efficient breeding methods.
We developed molecular markers and primer sets closely linked to the wheat Fusarium head blight resistance gene Qfhb.jaas-6B. We then used quantitative real-time PCR amplification and fluorescence signal scanning to identify whether wheat DNA samples carry the Fusarium head blight resistance gene, which can be used to assist in selective breeding.
It provides a stable set of molecular markers and primers, enabling rapid identification and breeding of wheat resistant to Fusarium head blight, shortening the breeding cycle, improving the resistance effect of disease-resistant varieties, and laying the foundation for cloning new genes.
