Bean pod mottle virus (BPMV) has become increasingly common in soybean throughout the north-central region of the United States. Yield loss assessments on southern soybean germplasm have reported reductions ranging from 3 to 52%. Currently, no soybean cultivars have been identified with resistance to BPMV. The objective of this study was to determine the impact of BPMV infection on soybean cultivars representing a broad range of northern soybean germ-plasm by comparing inoculated and noninoculated soybean plants in paired row studies. In all, 30 and 24 cultivars were evaluated in Nebraska (NE) in which soybean plants were inoculated at the V3 to V4 growth stage. Eleven cultivars from public and breeding lines were inoculated at the VC and R5 to R6 growth stages in Ohio (OH). Disease severity, yield, and percent seed coat mottling were assessed at both locations, whereas protein and oil content also were assessed at NE. Yield and percent seed coat mottling was significantly reduced following inoculation at the VC (OH) and V3 to V4 (NE) growth stages. In addition, seed oil and protein composition were impacted in 1 of the 2 years of the study. This study demonstrates that substantial yield losses can occur in soybean due to BPMV infection. In addition, protein and oil may be affected depending on the environment during the production season.
菜豆荚斑驳病毒（BPMV）在美国中北部地区的大豆中越来越常见。对南方大豆种质的产量损失评估报告称，产量降幅在3%至52%之间。目前，尚未鉴定出对BPMV具有抗性的大豆品种。本研究的目的是通过在成对行试验中比较接种和未接种的大豆植株，确定BPMV感染对代表广泛北方大豆种质的大豆品种的影响。在内布拉斯加州（NE）总共评估了30个和24个品种，大豆植株在V3至V4生长阶段接种。在俄亥俄州（OH），在VC和R5至R6生长阶段对接种了11个来自公共和育种系的品种。在两个地点都评估了病害严重程度、产量和种皮斑驳百分比，而在NE还评估了蛋白质和油含量。在VC（OH）和V3至V4（NE）生长阶段接种后，产量和种皮斑驳百分比显著降低。此外，在研究的两年中有一年种子油和蛋白质组成受到影响。本研究表明，BPMV感染会导致大豆大幅减产。此外，蛋白质和油可能会受到生产季节环境的影响。
