摘要
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。
Four-hundred-and-nineteen soybean accessions were inoculated with Phytophthora sojae（P.sojae）strain Pm14 on hypocotyls to identity the resistance of soybean germplasm to Phytophthora sojae in South China.The results showed that there were 14.32% accessions resistant to strain Pm14,13.84% accessions had the intermediate response and 71.84% were susceptible to strain Pm14.The accessions from Africa held the higher ratio of resistant materials than that of those accessions from China.
