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。
Artificial friction inoculation method was used in the net room to screen 54 new soybean varieties (lines) bred in Jilin province from 2009 to 2013 for the first and the third strains of northeast soybean mosaic virus Resistance identification. The results showed that 29 varieties (lines) and 53.71% of the total cultivars (lines) which showed disease resistance and above, and 2 varieties (lines) were susceptible to the disease, accounting for 3.70% of the total; No. 3 showed more than 25 varieties (lines) of resistance to disease and above, accounting for 46.29% of the total number of reference, 14 varieties (lines) showing susceptible disease, accounting for 25.93% of the total number of reference; No. 1 and No. 3 The strains showed resistance to disease and more varieties (lines) 25, accounting for 46.29% of the total number of reference. The identified resistant varieties (lines) can be used for soybean production as well as anti-source material for disease-resistant breeding.
