2009年贵州小麦条锈菌生理小种的鉴定

摘要

为弄清2009年贵州省境内小麦条锈菌生理小种的构成,采用小麦条锈菌常规鉴定方法对该年贵州小麦主要栽培区的78份标样进行了鉴定.结果表明,贵州省小麦条锈菌生理小种主要包括条中17、条中26、条中29、洛夫林13-8、条中31、条中32、水源11-2、水源11-5和水源11-14.其中,出现频率较高的生理小种主要是条中32、条中31和水源11-14,分别为48.72%、28.21%和6.41%.%78 samples collected from main wheat cultivation areas of Guizhou province were identified to study construction of wheat Puccinia striiformis physiological race in Guizhou. The results showed that 9 physiological races including CY17, CY26, CY29, Lovrinl3-8, CY31, CY32, SU2, SU5, SU14 and CY32 were identified and the occurrence frequency of CY32, CY31 and SU1l-14 was 48.72％, 28.21％and 6.41％ respectively.
