利用网室内人工接种法对103份不同省份大豆新品种(系)进行了弱毒株系SMV1和强毒株系SMV3的抗性鉴定。结果表明,抗SMV1株系的大豆新品种(系)有95份,占参试材料的92.2%,抗SMV3株系的品种(系)有53份,占参试材料的51.5%;兼抗SMV1和SMV3的有51份,占参试材料的49.5%,其中高抗SMV1和SMV3的有33份,占参试材料的32.0%,这部分材料在大豆实际生产中应充分加以利用。 The artificial inoculation method was used to detect the resistance of 103 strains of new soybean varieties (lines) to the attenuated strain SMV1 and the virulent strain SMV3. The results showed that there were 95 new varieties (lines) of anti-SMV1, accounting for 92.2% of the tested materials, 53 varieties (lines) of anti-SMV3 strains, accounting for 51.5% of the tested materials; And 51 of SMV3, accounting for 49.5% of the tested materials, of which 33 were highly resistant to SMV1 and SMV3, accounting for 32.0% of the tested materials, and these materials should be fully utilized in the actual production of soybean.
