| 摘 要： | 用全国统一稻瘟病菌生理小种鉴别寄主鉴定出的稻瘟病攻生理小种中，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。

| Abstract: | The virulence specialization of rice blast fungus, Magnaporthe grisea, was identified by using the supplementory rice varieties and hybrid rice combinations. Several dominant Chinese-races identi-fied using the Chinese differential varieties, such as ZA13, ZB13, ZC13, and ZC15, all could be furtherseparated into different pathotypes (subraces). The results suggested that the conventional method by using representative races to evaluate the resistance of rice varieties had its limitation. |
