摘　　要：１９９２—１９９４年应用我国统一的７个鉴别品种，鉴定了１９９２年采集分离的早、中、晚稻不同稻作类型共２２６个有效单孢菌株，区分为７群３４个生理小种，其中ＺＢ群为优势小种群，ＺＢ１５为优势小种．鉴定结果表明，早、中、晚稻稻瘟病菌生理小种存在着差异，早稻ＺＢ１５为优势小种，中稻ＺＢ１为优势小种，晚稻ＺＣ１５为优势小种．During 1992-1994,226 monoconidital isolates from different cropping type were identified and divided into 7 groups with 34 physiological racces,accordins to their reaction types to 7 Chinese differential vari eties. Among them,Zhong B group was the prevalent group and Zhong B15 was the predominant race. The results showed that there were different among early, middle-season and late rice. Thous B15, Zhong G1 andZhong C15 were the predominant races for early, middle-season and late rice, respectively.
