Abstract

Twenty-five accessions of Aegilops species were inoculated with Erysiphe graminis f. sp. tritici, f. sp. secalis, and f. sp. agropyri. The pattern of resistance/susceptibility was various and similar to that between cultivars and races. Genetic analysis using the gene-for-gene relationship suggested that accessions of Ae.bicornis and Ae. cylindrica carry Pml5, a gene for resistance to f. sp. secalis and f. sp. agropyri found in the D genome of common wheat. Evolutionary implications of these results were discussed.
禾草Erysiphe graminis种与种间互作的遗传分析
用小麦赤霉、玉米赤霉和agropyri赤霉分别接种了25个稻瘟病种。品种间和种间的抗性/敏感性差异较大。利用基因对基因关系进行的遗传分析表明;双角鸟和Ae。白茅携带Pml5基因,该基因是在普通小麦的D基因组中发现的一种抗黑穗病孢子虫和agropyri孢子虫的基因。讨论了这些结果的进化意义。
