| 摘 要： | 玉米瘤黑粉病能造成玉米严重减产,抗性系的选育对于减少病害具有重要价值.本研究在拔节期采用注射法接种瘤黑粉孢子,对第三染色体的8个染色体片段代换系进行抗性研究.结果表明,8个染色体片段代换系被代换的供体片段位点不同.抗瘤黑粉病表型有4种变异.其中,chr3-7系发病率、病级和病情指数均为0,表现高抗.与其他染色体片段代换系、Z3受体亲本及HB522供体亲本相比,ehr3-7系产量高,接种瘤黑粉孢子与对照产量差异不显著.chr3-7系对于抗瘤黑粉病遗传研究和育种具有重要意义.

| Abstract: | Common smut in maize reduces grain yield greatly.lines play an importment role to minimize the losses caused by common smut.At the elongation stage,Ustilago maydis fungus was injected into 8 maize chromosome segment introgress lines(CSILs).Eight CSILs have different chromosome segments of donor maize HB522 respectively.There are four kinds of varieties in eight CSILs.is highly resist to common smut.Chr3-7's grain yield is highest among other seven CSILs and two parents.chr3-7 is good SSILs for Resistance to... |
