| 摘 要： | 利用Flor基因对基因学说原理对条锈菌生理小种条中32号和水14所含的毒性基因进行推导，结果表明，条中32号含有VYr-1、VYr-2、VYr-3、VYr-6、VYr-7、VYr-8、VYr-9、VYr—11、VYr-12、VYr-18、VYr—Su、VYr—C5、VYr—SD、VYr—SpP等毒性基因，水14含有VYr-1、VYr-2、VYr-3、VYr-6、VYr-7、VYr-8、VYr-9、VYr—11、VYr-12、VYr-18、VYr—Su、VYr—C5、VYr—C591、VYr—SD、VYr—SpP等毒性基因。对条中32和水14的毒性基因谱的比较发现，水14含有较条中32号特异的VYr—C591毒性基因，致使近年来抗病品种C591田间抗病性丧失。

| Abstract: | According to Flor gene to gene assumption,we analysized the virulent genes of CY32 and Shui14 pathotype to Puccinia striiformis f.sp.triticiThe results showed that CY32 processed virulent genes such as VYr-1,VYr-2,VYr-3,VYr-6,VYr-7,VYr-8,VYr-9,VYr-11,VYr-12,VYr-18,VYr-Su,VYr-C5,VYr-SD,VYr-SpP.The Shui14 pathotype processed virulent genes such as VYr-1,VYr-2,VYr-3,VYr-6,VYr-7,VYr-8,VYr-9,VYr-11,VYr-12,VYr-18,VYr-Su,VYr-C5,VYr-C591,VYr-SD,VYr-spP.The results also showed that Shui14 pathotype had special virulent gene-VYr-C591,which deduced that the cultivar C591 lost its resistance in the field.This paper also discussed the using of resistant genes in the future in plant breeding. |
