用全国统一稻瘟病菌生理小种鉴别寄生鉴定出的猪瘟病菌生理小种中，典型的籼型优势小种，如：ZA13、ZB13、ZC13和ZC15，同一小种不同菌株的致病力不同，当加入辅助品种参测，均可再划分为不同的致病类型（亚小种）这一结果表明：传统的选用优势小种的代表性菌株来进行水稻品种抗瘟性鉴定的方法是有局限性的。
Among the races of M. gibberette strain identified by parasitic diseases of the Chinese single Magnaporthe grisea, the typical indica hybrids such as ZA13, ZB13, ZC13 and ZC15 were identified as pathogenicity of different strains of the same race , When adding auxiliary varieties of reference, can be further divided into different pathogenic types (subspecies) This result shows that: the traditional selection of dominant race of representative strains for rice blast resistance identification method is Limited.
