摘　　要：选用19个不同来源的稻瘟病菌株,对577份国外引进水稻新品种(系)进行不同稻瘟病菌的抗谱分析。研究结果表明,其中有11份品种(系)对19个参测菌株均具有抗性,1份品种(系)对19个参测菌株均为感病;19个参测菌株中,CH187、CH171的致病性最强,而CH362、CH154的致病性最弱;籼稻较粳稻表现出更强的稻瘟病抗性。Resistance spectrum analysis for 577 introduced new rice accessions was conducted using 19 rice blast strains. The results reflected that 11 accessions showed resistance to all test strains,while only one accession showed susceptibility to all strains. Among the 19 rice blast strains, CH187 and CH171 were responded with strongest pathogenicity, while CH362 and CH154 were weakest.Otherwise, indica subspecies has more powerful resistance than japonica subspecies.
