采用下胚轴伤口接种法,用大豆疫霉菌菌株Pm14对419份华南地区大豆育成品种及育种材料进行抗病性鉴定。结果鉴定出抗病资源60份,占鉴定资源总数的14.32%;中间反应类型有58份,占13.84%;感病材料301份,占71.84%。对资源的来源组成进行分析,统计结果表明,抗病性材料所占比例引自非洲的材料最高,国内次之,巴西最低。 Hypocotyl wound inoculation method was used to test the resistance of 419 soybean cultivars and breeding materials in South China with Phytophthora sojae strain Pm14. As a result, 60 disease-resistant resources were identified, accounting for 14.32% of the total identified resources. There were 58 intermediate reaction types (accounting for 13.84%) and 301 susceptible materials (71.84%). The source of the composition of the resources for analysis, statistics show that the proportion of disease-resistant materials from the highest material in Africa, followed by the domestic, Brazil lowest.
