Abstract: Rice blast caused great loss to rice yield and severely restricted rice production. It was the safest,most effective and economical method to breed stable,effective,broad-spectrum and long-lasting varieties of rice blast resistance by using the host′s own disease-resistant genes. With the rapid development of molecular biotechnology,more rice blast resistance genes and QTLs were exploited to create stable,broad-spectrum and long-lasting disease-resistant materials. In this paper,the structure,function and disease-resistance mechanism of cloned disease-resistant genes and QTLs were reviewed,and the application of these disease-resistant genes combined with molecular marker selective breeding,polymerized disease-resistant genes and gene editing techniques in disease-resistant breeding was summarized,and the prospect of rice blast resistance breeding was also discussed.

Key words: Blast, Disease-resistant genes, Molecular markers, Gene aggregation, Gene editing, Breeding
