Abstract:
Thirty-six isolates of cucumber downy mildew from Heilongjiang,Jilin,Liaoning,Beijing,Shandong,Jiangsu,Hubei,and Guangdong Province were amplified.Using SSR molecular marker method studied the SSR genetic diversity analysis of Pseudoperonospora cubensis.The results showed that China had bigger genetic differentiation,and abundant genetic diversity of Pseudoperonospora cubensis.In total of 170 bands were obtained,including 160 polymorphic bands accounting for 94.1%.D13 were screened as the best polymorphic primer from 11 primers.The NTSYS software was used to build the relationship dendrogram of P.cubensis,cluster analysis showed that the coefficient of similarity was from 0.43 to 1.00.There were certain correlations between SSR genetic diversity and geographical origin.
