| 摘 要： | 用我国7个统一鉴别品种鉴定了1995-2000年从福建省18个县(市)采集分离的204个稻瘟病菌有效单孢菌株,共鉴定到6群25个生理小种.1995-1999年ZB群出现频率最高,分布最广,ZB13为优势小种;2000年,ZC群出现频率高于ZB群,成为优势小种群,ZC13成为优势小种.最后简要讨论了近年来福建省稻瘟病菌生理小种的变化动态及鉴别品种的使用等问题.

Physiological race dynamics of the rice blast fungus in Fujian, China from 1995 to 2000 |
| |
| Abstract: | From 1995 to 2000, 204 monoconidial cultures of the rice blast fungus (Magnaporthe grisea) were isolated from 18 counties or cities in Fujian, China. The virulence of these isolates was assayed with a standard set of 7 differential rice varieties commonly used in China. Twenty five races belonging to 6 groups could be differentiated, of which ZB group was the most prevalent group and ZB13 was the predominant race during the period. But in 2000, ZC group was the most prevalent group, ZC13 was the predominant race. Finally the problem of differential varieties and variation of races in Fujian was discussed. |
