A barley yellow dwarf virus (BYDV)-resistant line HG295 was selected from a cross between cv. 77-5433 and Zhong 5 after extensive investigation in field, greenhouse and ELISA. Cytological analysis revealed that it was an euploid line and genetically stable. The existence of alien DNA in HG295 was identified by RAPD and Southern hybridization analyses showed that the alien DNAs came from Zhong 5 or Th. intermedium. The differences of BYDV resistance between L1 and HG295 are discussed.
