为明确不同燕麦(Avena sativa ) 种质抗病性差异, 2015 — 2016年对38份燕麦种质进行了人工接种坚黑穗病菌(Ustilago segetum var avenae)田间抗性鉴定和评价。结果表明,在供试的38份燕麦种质中,17份材料对坚黑穗病表现为免疫,9份表现高抗,6份表现抗,6份表现中感,分别占供试材料的44.7%、23.7%、15.8%和15.8%。通过鉴定获得的有效抗坚黑穗病种质,可为品种的合理布局及抗病育种提供核心抗源。

[Abstract]
In order to confirm the difference of oat germplasm resistance to Ustilago segetum var. avenae, the resistance of 38 oat germplasms was identified and evaluated by artificial inoculation under field condition from 2015 to 2016. The results show that 17 materials were immune, nine materials were highly resistant, six materials were resistant, and six materials were moderately susceptible, which accounted for 44.7%, 23.7%, 15.8% and 15.8% of 38 oat germplasms, respectively. Obtaining these effective resistance germplasms could provide core resistance source for breeding and reasonable layout of cultivars.
