Sudden death syndrome, caused by Fusarium solani f. sp. glycines, has caused severe damage to soybean production in recent years. One way to control sudden death syndrome is with resistant cultivars. Over a 3-year period, 2,335 publicly and privately developed soybean entries were inoculated and evaluated for their response to F. solani f. sp. glycines under greenhouse conditions. The entries were compared with the susceptible check, Great Lakes 3302 (GL3302), and the moderately resistant checks, plant introductions (PIs) 520733 and 567374. Thirty-eight entries were identified with moderate levels of resistance. Based on foliar ratings, there were no differences (P < 0.05) between the Roundup Ready and conventional cultivars. In all, 90 ancestral lines that represent 99% of the genes in modern U.S. cultivars and 55 lines found in the pedigrees of public cultivars reported to have some resistance were evaluated for their response to F. solani f. sp. glycines. Nine ancestral lines (Aoda, Kim, Jackson, Sioux, Mammoth Yellow, T117, PI 171450, PI 54615-1, and PI 71506) and 12 cultivars or experimental lines (Ina, D83-3349, LN98-4340, LN83-2356, Hartwig, Harosoy, Bedford, Merit, Cutler, Calland, Hill, and Evans) had disease ratings not significantly different (P < 0.05) from PI 520733 or PI 567374. PI 54610, a putative ancestral line, also was found to be moderately resistant.
由大豆尖镰孢菌引起的猝死综合征近年来给大豆生产造成了严重损失。控制猝死综合征的一种方法是使用抗性品种。在3年时间里，对2335个公共和私人培育的大豆品种进行了接种，并在温室条件下评估它们对大豆尖镰孢菌的反应。将这些品种与感病对照品种大湖3302（GL3302）以及中抗对照品种植物引进系（PI）520733和567374进行比较。鉴定出38个品种具有中等抗性水平。根据叶片评级，抗草甘膦品种和常规品种之间没有差异（P<0.05）。总共评估了代表现代美国品种99%基因的90个祖先系以及在据报道具有一定抗性的公共品种系谱中发现的55个品系对大豆尖镰孢菌的反应。9个祖先系（青豆、金豆、杰克逊、苏族、猛犸黄、T117、PI 171450、PI 54615-1和PI 71506）以及12个品种或试验品系（伊纳、D83-3349、LN98-4340、LN83-2356、哈特维希、哈罗索伊、贝德福德、梅里特、卡特勒、卡兰德、希尔和埃文斯）的病情评级与PI 520733或PI 567374没有显著差异（P<0.05）。推测的祖先系PI 54610也被发现具有中等抗性。
