The soybean aphid (Aphis glycines) is an important pest of soybean (Glycine max). Wild soybean (Glycine soja; also known as ‘soja’) has many useful traits, including some accessions with aphid resistance that may be incorporated into modern soybean cultivars. The objective of this work was to evaluate 76 selected soja accessions and 14 associated soybean accessions for resistance against two virulent colonies of soybean aphid in environmental-chamber experiments. In free-choice tests, soja accessions PI 407175, PI 407190, PI 407206, PI 407240, PI 507624 and PI 562558 were resistant against the Accrue colony, and PI 407191wf and PI 597458 C were resistant against the Volga16 colony. None of the soybean test accessions except the resistant check, PI 437696, showed resistance against either colony in free-choice tests. In no-choice tests, soja accession PI 507624 showed strong resistance against the Accrue colony; whereas PI 407240 and PI 407190 had intermediate aphid levels; PI 597458 C showed strong resistance to Volga16 aphids, and PI 407191wf had an intermediate level of resistance. Based on results from both sets of tests, soja accessions PI 507624 and PI 597458 C may be strong candidates in breeding programs to develop aphid-resistant soybean cultivars.

选定的野生大豆和相关大豆品种对甘氨酸蚜虫（半翅目：蚜科）两个毒力菌落的抗性

大豆蚜(Aphis glyines)是大豆(Glycine max)的重要害虫。野生大豆（Glycine soja；也称为“soja”）具有许多有用的性状，包括一些具有抗蚜虫性的种质，这些种质可以被纳入现代大豆栽培品种。这项工作的目的是在环境室实验中评估 76 个选定的大豆种质和 14 个相关大豆种质对大豆蚜虫的两个有毒菌落的抗性。在自由选择试验中，大豆种质 PI 407175、PI 407190、PI 407206、PI 407240、PI 507624 和 PI 562558 对 Accrue 菌落具有抗性，而 PI 407191wf7 和 585 对 PI 16 菌落具有抗性。除了抗性检查 PI 437696 外，没有任何大豆测试种质在自由选择试验中显示对任一菌落的抗性。在无选择测试中，大豆种质 PI 507624 对 Accrue 菌落表现出很强的抗性；而 PI 407240 和 PI 407190 的蚜虫水平处于中等水平；PI 597458 C 对 Volga16 蚜虫表现出很强的抗性，PI 407191wf 具有中等水平的抗性。根据两组测试的结果，大豆种质 PI 507624 和 PI 597458 C 可能是开发抗蚜虫大豆品种的育种计划的有力候选者。
