土壤中棉花黄萎病菌快速检测技术研究

Verticillium wilt,caused by Verticillium dahliae,is the most important disease of cotton.In this work,the previously developed defoliating(D) and nondefoliating(ND) V.dahliae-specific primers were adopted for detection of pathotypes of V.dahliae in soil by using nested PCR.The results showed that the detection assay was efficient when used in infested soil and was an useful technique for rapid and accurate assessment of soil contamination by V.dahliae.
