In order to screening the resistant wheat germplasms to the English grain aphid,Sitobion avenae,and the Barely yellow dwarf virus( BYDV),the resistance of 36 wheat varieties,which were introduced from abroad,or hybrids of Triticum aestivum with T. turgidum,T. monococcum,Thinopyrum ponticum or Secale cereale to both S. avenae and BYDV were evaluated in the field in 2007 and 2010. The correlations between the susceptibilities of the wheat germplasms to the aphid and to the BYDV were analyzed. 11. 11% of the 3...
