前言锈病是小麦生产上的严重威胁,因此,抗锈育种已引起育种家和病理学家的极大关注。大多数抗锈育种工作主要是将抗病性转育到其它感病而农艺性状优良的品种中。这样获得的纯系品种可以保持一定时间的抗性,但由于病原体的平行演变,其抗性丧失。结果,新育成的品种对新的病原体生理小种或生物型又表现 Introduction Rust is a serious threat to wheat production and therefore, rust-resistant breeding has drawn the great attention of breeders and pathologists. Most anti-rust breeding work is mainly to disease resistance to other susceptible and agronomic traits of fine varieties. The pure lines obtained in this way are resistant to some time but their resistance is lost due to the parallel evolution of pathogens. As a result, newly bred varieties show up for new pathogen race or biotypes
