【摘要】 在网室内采用人工磨擦接种鉴定方法,对2009~2013年吉林省选育出的54份大豆新品种(系)进行了针对东北大豆花叶病毒主要流行株系1号株系和3号株系的抗性鉴定。鉴定结果表明:对1号株系表现抗病及以上的品种(系)29份,占参鉴总数的53.71%,表现感病的品种(系)2份,占参鉴总数的3.70%;对3号株系表现抗病及以上的品种(系)25份,占参鉴总数的46.29%,表现感病的品种(系)14份,占参鉴总数的25.93%;对1号和3号株系均表现抗病及以上的品种(系)25份,占参鉴总数的46.29%。鉴定出的抗性品种(系)既可用于大豆生产,也可作为抗源材料用于抗病育种。更多还原

【Abstract】 In 2009~2013, the resistance of 54 new soybean varieties(lines) of Jilin Province to major SMV strains of northeast was identified by the method of artificial inoculation identification in net house. The results showed that 29 varieties(lines) were resistant to strains SMVI, account for 53.71% of the total. 2 varieties(lines)were susceptible to strains SMVI, account for 3.70% of the total. 25 varieties(lines) were resistant to strains SMVIII,account for 46.29% of the total. 14 varieties(lines) were susceptible to strains SMVIII, account for 25.93% of the to-tal. 25 varieties(lines) were resistant to both strains SMVI and SMVIII, account for 46.29% of the total. These resis-tant varieties(lines) can not only be used directly in soybean production, but also be used as resistant resources in resistant breeding.更多还原
