摘　　要：应用３个籼稻、４个粳稻组成的中国鉴别品种将黑龙江省１１０个稻瘟病菌菌株划分为４群７个生理小种。用日本清泽的１２个单基因抗性鉴别品种将上述菌株划分为７７个生理小种。对＋、ｔｉ－ａ、Ｐｉ－ｋ、Ｐｉ－ｚ基因致病频率高（７０．４％～８９％）的生理小种遍布全省各稻区；对Ｐｉ－ｔ、Ｐｉ－ｂ、Ｐｉ－ｚｔ基因致病频率低（０～１９．３％）的生理小种分布窄，这３个基因可用于抗病育种。The 110 isolates of Piricularia oryzae in Heilongjiang Province were classified into 4 groups and 7 races by 7 Chinese differential cultivars and into 77 races by 12 mono resistant gene differential caultivars of Kiyosawa (Japan). High virulence frequence (70.4% 89%) occurred with genotypes of+, ti a, Pi k, Pi z, and those races were widely distributed over all rice production areas of the Province. Low virulence frequency (0 19.3%) occurred with genotypes of Pi t, Pi b and Pi zt. These three genes could be used for blast resistant breeding. Differentials of Kiyosawa were suitable for differentiating races of Piricularia oryzae in Heilongjiang Province.
