摘　　要：为了详细了解我国近几年来育成的北方春大豆品系对花叶病毒病的抗性表现,本研究通过分析2003～2007年的国家北方春大豆品种区域试验和生产试验病毒病2个流行株系(SMV1和SMV3)抗性鉴定数据,筛选兼抗SMV1号和SMV3号株系的抗原有19份,专抗SMV1号株系的抗原55份,专抗SMV3号株系的抗原20份,并发现辽宁省的新品系对2个株系的抗性表现都是最好的,尤其是表现抗病级别(R)的品系较多;而黑龙江省对2个株系的抗性表现都是最差的,尤其是对3号株系,大部分表现感病。建议黑龙江省今后要重视花叶病毒与抗性育种,可以考虑从辽宁和吉林两省引入抗原,进行品种选育和抗性改良。In order to know the resistance of northern spring soybean strains to soybean mosaic virus, data of identification to SMV1 and SMV3 from 2003 to 2007 were analyzed in the paper. 19 resistance strains which were resistant both to SMV1 and SMV3 were selected, 55 resistance strains were discovered to be resistant to SMV1, and 20 strains resistant to SMV3. It was found that new strains released in Liaoning Province were more resistant to SMV1 or SMV3, most of which were classified as resistant varieties. Whereas new strains released in Heilongjiang Province were less resistant to both SMV1 and SMV3, in particularly most materials were susceptible to SMV3. It was suggested that resistance breeding to Soybean mosaic virus should be stressed in Heilongjiang Province and antigen from Liaoning Province and Jilin Province may be introduced to breed new variety and improve its resistance.
