中文摘要：

利用黄淮地区广范分布的优势大豆花叶病毒（soybean mosaicvies，SMV）株系SC3、SC7和大豆胞囊线虫1号生理小种，分别对2009—2015年安徽省大豆区试和预试参试品种（系）523份（次）进行抗病性评价。结果显示：对SC3表现抗病（高抗、抗病和中抗）的材料有262份，占参试材料总数的50．1％；抗SC7的材料有274份，占52．4％；同时对SC3和SC7表现高抗的材料仅有HD21116。同时发现参加安徽省区试预试的大豆新品种（系）在不同年份间对SMV的病情指数存在显著差异。对SCN的抗性结果显示，远育8号、阜09-242和SK8—3—3等8份表现中抗，占鉴定总数的1．8％，表现中感的有43份，占9．9％，有383份材料表现高感，占鉴定总数的比率高达88．3％，说明多数大豆品种（系）对SCN的综合抗性较差。对鉴定结果的综合分析发现，只有1份新品系同时对SMV和SCN表现中抗，为SK8-3-3。

英文摘要：

The resistance of 523 new bred soybean varieties（lines） from Anhui provincial regional trials in 2009 -2015 was tested using soybean mosaic virus（SMV） strains SC3 and SC7 and soybean cyst nematode （SCN） race No. 1, respectively. Among the 523 varieties（lines） inoculated by SC3 and SC7, 262 （50. 1% ） and 274 （52.4%） exhibited resistance（ high resistance, resistance and moderate resistance）, repectively. Only one line （HD21116） showed high resistance to both SC3 and SC7. The study also showed that the resistance level of soybean new varieties（lines） to SMV were significantly different in different years. To SCN, eight varieties （lines） containing Yuanyu 8, Fu 09-242 and SK8-3-3 were moderate resistance （ 1.8% ）, 43 and 383 soybean varieties（lines） were susceptibility and high susceptibility, accounting for 9. 9% and 88. 3%, respectively. The resistance of most the soybean varieties（lines） were not high to SCN. Only one soybean line SK8-3-3 was moderate resistance to both SMV and SCN.
