从1981—1986年对吉林、辽宁两省保存的大豆品种资源进行了抗大豆花叶病(SMV)、灰斑病(Cercospora sojina)和霜霉病(Peronospora manschurica)的抗性鉴定。结果在957个品种抗花叶病鉴定中,没有发现免疫品种,在1781个品种抗灰斑病鉴定中,对灰斑病免疫的品种81个,占4.5％;在1330个品种抗霜霉病鉴定中,对霜霉病免疫的品种有143个,占10.8％。所有参加鉴定的品种,没有对三种病同时免疫的。兼免疫灰斑病和霜霉病的品种7个,占0.5％,农家种灌水铁荚青在所有参加鉴定品种中表现抗花叶病、高抗灰斑病、免疫霜霉病,已收入大豆品种资源目录。可做为多抗性抗源,供抗病育种利用。
From 1981 to 1986, the soybean cultivars conserved in Jilin and Liaoning Provinces were tested for resistance to soybean mosaic disease (SMV), Cercospora sojina and Peronospora manschurica. Results There was no immune variety in the identification of anti-mosaic disease in 957 cultivars. Among the 1781 cultivars, 69 were immunized against Cercospora sojina, accounting for 4.5% of the total, while 1330 were resistant to downy mildew In the appraisal, there were 143 varieties of downy mildew immunity, accounting for 10.8%. All participating species were not immunized against the three diseases at the same time. Seven of them were also resistant to gray-spot and downy mildew, accounting for 0.5% of the total. Among them, all the cultivars of Ironstrodia hybrids showed resistance to mosaic disease, high resistance to gray leaf spot and downy mildew, Variety of resources directory. Can be used as multi-resistance source for disease-resistant breeding use.
