摘要
澳大利亚小麦品种Sunco成株期对中国条锈病小种条中32(CY32)表现高抗-免疫,而小麦品种川育12则表现为高感。利用Sunco/川育12的双单倍体(DH)群体对Sunco进行抗条锈病遗传研究,结果表明,品种Sunco可能具有持久抗性,抗性是由一对主效基因和两对微效基因联合作用的结果;主效基因的抗性反应为抗-中抗(R-MR),微效基因单独存在作用不明显,但与主效基因结合起来会加强抗条锈病能力。同时对微效多基因的持久抗性利用作了初步探讨。
Australian wheat variety Sunco carry good adult plant resistance to Chinese stripe rust races CY32. Wheat variety Chuanyu12 released in Sichuan province is terrible adult plant susceptible. A DH population developed from Sunco/Chuanyu12 was used for genetic analysis of Chinese stripe rust races resistance on Sunco. The results show Sunco combines one major resistance gene with two minor genes, and the major gene is resistant or middle resistant to stripe rust. If carried only minor gene （s）, the material will be susceptible to stripe rust, if combined major gene with minor gene （s）, it can express good adult plant resistance to stripe rust.
