中国水稻近等基因系在黑龙江省稻瘟病菌生理小种中的应用研究

摘要

In order to seek races of Pyricularia grisea distinction varieties,which adapt research of Heilongjiang Province Pathogenic,Chinese Near-isogenic lines（NILs） of rice applied to the monitoring study in Heilongjiang Province Pathogenic races of Pyricularia grisea for the first time.The analysis of compare Chinese No.1 set 7 distinction varieties with Pathogenic races of Pyricularia grisea proofs that the differentiating ability of Chinese NILs of rice is strongly,they are also playing a part in refining Chinese races of a sort.The study also showed that Chinese NILs of rice are suitable for identificating Heilongjiang rice areas Pathogenic races of Pyricularia grisea.%为了寻找适应于黑龙江省稻瘟病菌生理小种研究的鉴别品种,首次将中国水稻近等基因系应用于黑龙江省稻瘟病菌生理小种监测研究中,采用中国第一套7个鉴别品种对生理小种的鉴别力与其进行比较分析,证明中国水稻近等基因系具有较强的鉴别能力,对同一中国小种具有细划作用,适宜黑龙江省稻区稻瘟病菌生理小种鉴定研究。
