稻瘟病菌群体遗传结构的研究进展

Advances on Poputation Genetics of Rice Blast Fungus

稻梨孢引起的稻瘟病是世界水稻生产的最重要病害,严重影响水稻的产量和米质。文中综述了分子标记技术在稻瘟病菌群体遗传结构研究上的应用,分析了病原菌遗传宗谱的特点及其与致病谱的关系,探讨了导致稻瘟病菌群体遗传结构发生变化的相关因素。

Rice blast caused by Pyricularia grisea was the most important disease in the rice production and seriously influenced the yield and quality. This paper reviewed the application of molecular markers to the analysis of genetic population of structure in blast pathogen and stated the quality of genetic lineages. At the same time the relationship between pathotype and genetic lineages of blast pathogens was analized and the relative factors resulting in the changes of blast pathogen population structure were studied.
