摘要： The line of T240-6 was selected from 32 SC_2 lines of immature embryo culture of T240 (common wheat (Triticum aestivum L.) x Wheat-Haynaldia villosa (L.) Schur. 6D/6V substitution line) through powdery mildew characterization, glutamate oxaloacetate transaminase (GOT) enzyme and gliadin (Gli) analyses and in situ hybridization. All of the individual plants resistant to powdery mildew lacked the locus of GOT at 6VL arm (GOT-V_2) and had gliadin locus at 6VS arm (Gli-V_2) of Haynaldia villosa. All the plants resistant to powdery mildew had one or two telocentric chromosomes that did not pair with wheat chromosomes but paired between themselves. T240-6 was identified as a telocentric line through in situ hybridization.
