采用田间自然发病鉴定方法对来自南方8个省的340份大豆地方品种及育成品种(系)进行了大豆花叶病毒病(SMV)抗性初步鉴定筛选。结果表明:在340份大豆资源中,免疫材料21份,抗病材料159份,中间型材料100份,感病材料44份,高感材料16份,分别占供试材料的6.18%、46.76%、29.41%、12.94%和4.71%。免疫型材料主要来自湖南、江西和广东。选出小区产量高且对SMV免疫的育成品种(系)1份:粤夏124,地方品种4份:ZDD06803、ZDD14319、ZDD06529、ZDD14389,这些材料可以作为广西SMV抗性育种的备选材料。
A total of 340 soybean landraces and bred varieties (lines) from 8 provinces in the south were initially identified and screened for resistance to soybean mosaic virus (SMV) using field natural appraisal methods. The results showed that among 340 soybean resources, 21 immunological materials, 159 resistant materials, 100 intermediate materials, 44 susceptible materials and 16 high sensitive materials accounted for 6.18% and 46.76% of the tested materials respectively, , 29.41%, 12.94% and 4.71% respectively. Immune materials are mainly from Hunan, Jiangxi and Guangdong. One of the breeding varieties (lines) with high yield and immune to SMV was selected: Guangdong 124 and local varieties 4: ZDD06803, ZDD14319, ZDD06529 and ZDD14389. These materials could be used as alternative materials for SMV resistant breeding in Guangxi.
