摘　　要：由大豆花叶病毒(Soybean mosaic virus,SMV)引起的大豆花叶病毒病是大豆生产中普遍发生、危害严重的一种病毒病害。为筛选抗SMV品种,采用我国黄淮大豆产区SMV优势株系SC3和SC7,人工摩擦接种评价了815份大豆品系对SMV的抗性并分析了其亲本来源。结果表明:对SMV株系SC3和SC7分别表现高抗的有136和42份,占鉴定品系数的16. 69%和5. 15%;对SC3和SC7均表现高抗的有13份,占比为1. 60%;对两个株系均表现抗病的有215份,占26. 38%。表现高抗和抗病的大豆品系如H62509、H63001、H61927、W633619和W636513等通过审定后进行推广将对SMV的控制起到关键作用。对选育品系的亲本来源进行分析发现,以山东材料作为母本育成高抗品系的概率最高,而用安徽材料作为父本育成高抗品系的概率最高。研究结果将为大豆抗SMV育种提供可参考的信息。Soybean mosaic disease, caused by soybean mosaic virus （ SMV）, is one of the most devastating soybean diseases worldwide. In order to screen the resistant soybean varieties, total 815 of new bred soybean lines were evaluated for resistance to SMV by inoculation with two SMV prevalent strains SC3 and SC7. The results showed that among 815 lines inoculated with SC3 and SC7, 136 （16. 69% ） and 42 （5.15%） exhibited high resistance, respectively. Thirteen lines showed high resist-anee to beth SC3 and SC7, accounting for 1.60%, 215 lines were resistance to the two strains （26. 38% ）. The resistant soy-bean varieties, such as H62509, H63001, H61927, W633619 and W636513 et al. , should be applied and popularized as resistance resources in the field production and would play crucial roles. The analysis of the parental origins of new lines showed that the probability of soybean lines, were bred by the female from Shandong, exhibited high resistance was the highest, while the probability of soybean lines with high resistance were bred by the male from Anhui was the highest. These results will pro-vide useful information for improvement of SMV resistance breeding.
