Abstract

Abstract:

Over the past two decades, global scientists have continuously explored the field of rice-pathogen/pest interactions, achieving numerous significant outcomes. They have not only elucidated the genetics and molecular mechanisms underlying host resistance but also provided critical gene resources, strategies, and technical support for molecular breeding of rice varieties resistant to pests and diseases, which holds important theoretical and practical implications for green and safe production of rice. This paper reviewed the research progress in cloning and understanding the molecular mechanisms of resistance genes against rice blast, bacterial blight, and the brown planthopper, introduced the practices and advancements made by Longping High-tech in the molecular breeding of hybrid rice for resistance to diseases and pests, analyzed the challenges faced by current molecular breeding efforts for disease and pest resistance, and provided an outlook on future development trends.

Key words: rice, pests and diseases, resistance genes, molecular breeding
