摘　　要：人工接种我国黄淮、长江流域及南方大豆产区流行SMV株系SC3、SC7和SC15、SC18及黄淮海流行SCN1号生理小种，对国内主要育种单位近年来选育的参加2010—2012国家大豆新品种区域试验的122个参试品种进行抗性鉴定和评价。结果表明：对SC3表现较好抗性（高抗、抗病）的品种32个，占接种该株系品种总数的32％，对SC7表现较好抗性的品种34个，占接种该株系品种总数的34％，同时对SC3和SC7表现较好抗性的品种22个，占接种2个株系品种总数的22％；对SC15表现较好抗性的品种3个，占接种该株系品种总数的13．6％，对SC18表现较好抗性的品种3个，占接种该株系品种总数的13．6％，同时对SC15和SC18表现较好抗性品种的2个，占接种2个株系品种总数的9．09％；近10年SMV抗性鉴定结果分析表明，我国抗SMV育种水平有所提高，新培育的中抗品种比率显著增加，感病品种比率下降。SCN抗性鉴定结果显示，仅沧豆11为高抗，高感品种34个，分别占参试品种总数的1．96％和66．67％，其余为中间型（中抗和中感）。近10年SCN抗性鉴定结果显示我国抗SCN育种水平没有明显改善。鉴定出鲁98011-14、沧豆11、开豆41、鲁97013-1兼抗SMV和SCN两种病害。Soybean Mosaic Virus （SMV）and soybean cyst nematode（SCN） are the two most important diseases causing soybean yield loss and seed quality deterioration. A total of 122 soybean cultivars, which were from the national soybean regional trials of China during 2010-2012 ,were evaluated for resistance to SMV and SCN at seedling stage in a net room with ahid-free inoculated with 4 prevalent SMV strains, SC3, SC7 and SC15, SC18 and SCN Race 1. The results showed that 32,34 and 22 soybean cultivars were resistant to SC3, SC7 and both, accounting for 32%, 34% and 22% of the soybean cuhivars inoculated with the corresponding strain （s）, respectively; 3,3 and 2 soybean cuhivars were resistant to SC15, SC18 and both, accounting for 13.6%, 13.6% and 9.09% of the soybean cuhivars inoculated with the corresponding strain（ s）, respectively. The results of identification of resistance for SMV from 2003 to 2012 showed that some progress of soybean breeding for SMV resistance had been made,the ratio of moderate resistant soybean cuhivars increased while susceptible cuhivars decreased significantly. The results of identification for SCN resistance of 51 soybean cultivars from HuangHuaiHai valleys showed that only one soybean cv. Cangdou 1 was high resistant ,34 were high susceptible euhivars, accounting for 1.96% and 66.67% of the total, respectively, and the other were moderate resistance and susceptible cuhivars. The ten years＇ results of identification of resistance for SCN showed that little progress of soybean breeding for SCN resistance had been made. Soybean cv. Lu 98011-ld, Cangdou 11, Kaidou 41 and Lu 97013-1 ,were resistant to both SMV and SCN.
