小麦赤霉病的遗传抗性是减少小麦籽粒产量和品质损失所必需的。由于抗性来源的不适应性和不完全，以及混乱的环境影响，使种质筛选变得困难，抗病品种的发展受到了阻碍。赤霉病抗性QTL的DNA标记已被确定，可用于加速抗性基因向适应种质的导入。本研究的目的是在两个春小麦重组自交系群体中定位与赤霉病抗性基因连锁的其他DNA标记，这两个群体都分离了来自广泛使用的抗源‘苏麦3号’的基因。
Genetic resistance to Fusarium head blight (FHB), caused by Fusarium graminearum, is necessary to reduce the wheat grain yield and quality losses caused by this disease. Development of resistant cultivars has been slowed by poorly adapted and incomplete resistance sources and confounding environmental effects that make screening of germplasm difficult. DNA markers for FHB resistance QTLs have been identified and may be used to speed the introgression of resistance genes into adapted germplasm. This study was conduct ed to identify and map additional DNA markers linked to genes controlling FHB resistance in two spring wheat recombinant inbred populations, both segregating for genes from the widely used resistance source 'Sumai 3'.
