采用喷雾接种的方法，筛选了不同种类小麦野生近缘种对枯萎病（FHB）的抗性。绝大多数种和供种对FHB敏感或高度敏感。小麦（Triticum timopheevi） （P95-99.1-1）、沙草（Agropyron desertorum）（9439957）和羊草（Elymus vaillantianus）（531552）对赤霉病有高度抗性，其他品种的timopheevi对赤霉病有敏感性。连续两个季节的喷雾接种和点接种综合评价表明，P95-99.1-1菌株的抗性是由于对真菌初始感染的抗性增强（1型抗性），而不是由于传播的减少（2型抗性）。一组小麦。采用喷雾接种法对timopheevi（编号P95-99.1-1）侵染系进行了连续两季的FHB抗性筛选。大多数渗渗系作为小麦受体（Paragon）对赤霉病的敏感性相似，但在小麦背景下，将小麦3BS染色体的末端部分替换成大小相似的timopheevii的3G部分显著增强了对赤霉病的抗性。
A diverse panel of wheat wild relative species was screened for resistance to Fusarium head blight (FHB) by spray inoculation. The great majority of species and accessions were susceptible or highly susceptible to FHB. Accessions of Triticum timopheevii (P95-99.1-1), Agropyron desertorum (9439957), and Elymus vaillantianus (531552) were highly resistant to FHB while additional accessions of T. timopheevii were found to be susceptible to FHB. A combination of spray and point inoculation assessments over two consecutive seasons indicated that the resistance in accession P95-99.1-1 was due to enhanced resistance to initial infection of the fungus (type 1 resistance), and not to reduction in spread (type 2 resistance). A panel of wheat-T. timopheevii (accession P95-99.1-1) introgression lines was screened for FHB resistance over two consecutive seasons using spray inoculation. Most introgression lines were similar in susceptibility to FHB as the wheat recipient (Paragon) but substitution of the terminal portion of chromosome 3BS of wheat with a similar-sized portion of 3G of T. timopheevii significantly enhanced FHB resistance in the wheat background.
