| 摘 要： | 用中国稻瘟病生理小种鉴别品种,对2006年在黑龙江省水稻主产区采集稻瘟病标样中分离出的134个单孢菌株进行鉴定,鉴定出6个群14个生理小种(ZC群生理小种没有出现),ZE群为优势菌群,其次为ZG群、ZF群和ZA群;从稻瘟病优势生理小种分布得出,ZE1和ZG1分布地域比ZF1和ZE3广;全省不同积温带稻瘟病优势小种的分布结果表明,第一积温带和第三积温带(早、晚)稻瘟病生理小种分化简单,第二积温带(早、晚)稻瘟病生理小种分化复杂,ZG、ZE、ZF、ZA为全省的优势菌群,但ZB和ZD菌群有上升的趋势。

| Abstract: | Total 134 isolates of Magnaporthe grisea were collected and identified in Heilongjiang in 2006. Among them, six groups and 14 races were identified using Chinese identification rice varieties. The prevalence group was ZE and the second prevalence groups were ZG, ZF and ZA, but ZC group didn’t shown. According to the distribution of prevalence race, the distribution regions of ZE1 and ZG1 were more vast than that of ZF1 and ZE3. The differentiations of physiologic races of Magnaporthe grisea were simple in Heilongjiang in the first and third temperate zones and were complex in the second temperate zone, ZG, ZE, ZF, ZA were prevalence groups of Heilongjiang Province, but ZB and ZD groups had the tendency of rising. |
