| 中文摘要:为明确普通小麦-簇毛麦易位系材料对不同条锈菌系的抗病水平、抗病基因组成和易位系间抗病基因关系, 对V9125-3和V9125-4易位系进行了苗期抗条锈性遗传分析, 并利用V9125-2抗条锈基因YrWV的2个侧翼分子标记, 分析了3个易位系抗病基因间的关系。结果表明, 2个易位系对当前国内7个优势菌系均表现良好的抗病性, 但对不同菌系抗病性的抗病基因遗传特点有所不同。V9125-3对CYR29、CYR30和CYR31的抗病性由2对显性基因独立控制, 对CYR32、CYR33和Sun11-11的抗病性由1显1隐2对基因控制, 对Sun11-4的抗病性由2对显性基因互补控制;V9125-4对CYR30、Sun11-4和Sun11-11的抗病性由2对显性基因独立控制, 对CYR32和CYR33的抗病性由1显1隐2对基因控制, 对CYR29和CYR31的抗病性由2对显性基因互补控制;V9125-3对CYR29的抗病基因其中之一可能是YrWV, 另一个为未知基因。 |

| Abstract:For assessing the resistance level of translocation lines to different Puccinia striiformis f.sp. tritici races and dissecting the organization of resistance genes and their relationships among different lines, the stripe rust resistance inheritance characteristics of two translocation lines at seedling stage were analyzed. Using two flanking markers of the resistance gene YrWV from translocation line V9125-2, the relationships between the resistant genes in three translocation lines were analyzed. The results revealed that two translocation lines were high resistant to seven Chinese dominant races of stripe rust and resistant genes contained by these two lines to different races were distinguished in quantity and trait. In V9125-3, resistance to CYR29, CYR30 and CYR31 is controlled by two dominant genes, to CYR32, CYR33 and Sun11-11 controlled by one dominant gene and one recessive gene, to Sun11-4 controlled by complementation of two dominant genes; in V9125-4, resistance to CYR30, Sun11-4 and Sun11-11 are controlled by two dominant genes, to CYR32, CYR33 controlled by one dominant gene and one recessive gene, to CYR29 and CYR31 controlled by complementation of two dominant genes. Genetic analysis data associated with molecular marker tests showed that one of the two resistant genes which control resistance of V9125-3 to CYR29 may be YrWV, another gene is unknown. |
