通过对国内外已鉴定出的主要抗青枯病花生种质进行人工接种和多克隆抗体检测，研究栽培花生对青枯菌潜伏侵染的反应。根据青枯菌在花生植株体内的潜伏定殖部位，将抗病花生品种划分为５个反应类型，类型间抗性水平和稳定性存在明显差异。通过分析潜伏定殖率与植株生长发育的关系，发现不同花生品种受潜伏侵染影响的程度不同，鉴定出的几个产量水平高而且受潜伏侵染影响较小材料，可以作为进一步育种的抗源亲本。
The peanut germplasm which has been identified as the major resistance to bacterial wilt at home and abroad was inoculated by artificial inoculation and polyclonal antibody. The response of cultivated peanut to latent infection of R. solanacearum was studied. According to the latent colonization sites of R. solanacearum in peanut plants, the resistant peanut varieties were divided into five reaction types, and there was a significant difference in the level of resistance and the stability between them. By analyzing the relationship between latent colonization rate and plant growth and development, it was found that different peanut cultivars were affected by the latent infection to some extent. Several high-yielding cultivars with less affected by latent infection were identified as resistant to further breeding Source parents.
