在接种我国大豆产区主要流行SMV株系SC-3及SC-7和SCN 1号生理小种的条件下,对新育成的参加2004~2007年国家及江苏、北京、山东等省市大豆区试的品种分别进行了抗性评价。结果表明:在抗SMV鉴定的334个品种中,对SC-3抗性较好(高抗和抗病)的品种数有148个,占参试品种数的44.31%;对SC-7抗性较好的有71个,占参试品种数的21.26%。同时对2个株系抗性表现较好的有55个,占参试品种数的16.47%。这些抗性较好的品种既可用于大豆生产,也可作为抗源用于抗病品种选育和与抗性相关的研究。研究还显示,来自于西北和黄淮海大豆产区的参试品种一般抗性较好。抗SCN鉴定的193个大豆品种中,未发现高抗品种,中抗品种有25个,占12.92%。汾9877-10、邯601、蒙9793-1、沧豆九号等7个品种兼抗SMV和SCN 2种病害。
Under the conditions of SC-3, SC-7 and SCN-1, the main epidemic SMV strains in China’s soybean producing areas, the newly-emerged soybean plants participating in the national and soybean provinces of Jiangsu, Beijing and Shandong provinces from 2004 to 2007 The tested varieties were evaluated for resistance. The results showed that among the 334 varieties identified by SMV, 148 were resistant to SC-3 (high resistance and disease resistance), accounting for 44.31% of the tested varieties. The resistance to SC-7 The better 71, accounting for 21.26% of the varieties tested. At the same time, 55 strains with good resistance to 2 strains were obtained, accounting for 16.47% of the tested varieties. These better resistant varieties can be used for both soybean production and as a source of resistance for resistance breeding and resistance-related research. The study also showed that the tested varieties from the Northwest and Huang-Huai-Hai soybean producing areas generally had better resistance. Of the 193 soybean cultivars identified by SCN, no high resistant varieties were found, and 25 were medium resistant varieties (12.92%). Fen 9877-10, Handan 601, Mongolia 9793-1, Cang Dou 9 and other seven varieties and anti-SMV and SCN 2 kinds of diseases.
