Abstract: | Breeding materials derived from CPI113500, amphidiploid ofT. turgidum × Ag.pulcherrimum with barley yellow dwarf virus (BYDV) resistance, were evaluated by using BYDV resistance test, morphology observation, cytogenetics
analysis, aneuploid analysis, isozyme electrophoresis,in situ hybridization. Two new germplasms resistant to BYDV were obtained. They were T.aestivum-Ag. pulcherrimum disomic addition line 96S16-11, andT. aestivum-Ag. pulcherrimum disomic substitution line 96W14-9.
