Abstract:
A total of 273 virus samples of SMV were collected from 28 locations distributed in 13 counties of Hebei province in 2012.The isolates were biologically purified from collected samples and detected by ELISA and RT-PCR.Then,SMV isolates were classified by the unified national identification system.Finally,67 virus isolates were obtained and 56 virus isolates were identified to be SMV isolates by ELISA and RT-PCR.Base on the differential host responses to these isolates,these SMV isolates were classified into 9 strains.Compared with previous studies,composition and distribution of SMV strains in Hebei had showed some changes,however SC7 and SC11 were still popular strain;the percentage of SC8 strain decreased;SC12,SC13 and SC15 were undetected;three new strains SC1,SC3 and SC18 were first discovered in Hebei,and the development of SC3 strains should be given more attention.
