大豆种皮斑驳通常是大豆种植者和大豆工业的问题症状。用豆荚斑驳病毒（BPMV）、大豆花叶病毒（SMV）及两种病毒在田间防虫笼中对8个大豆品系进行了接种，并在收获时对种子的斑驳率进行了测定。从2年多的实验结果表明，植物感染BPMV和SMV，单独或组合，产生种皮斑驳，而noninjured植物产生很少或根本没有斑驳的种子。BPMV和SMV接种在同一植株上并不总是导致较高的斑驳种子的百分比比BPMV或SMV单独。病毒、株系和株系间互作对种皮斑驳有显著影响。威廉姆斯等株系L77-5632中的非种皮斑驳基因（Im）对SMV引起的斑驳提供有限的保护（如果有的话），而对BPMV没有保护。威廉姆斯分离系L 85 -2308中的花生斑驳病毒抗性基因Rpv 1对SMV引起的斑驳没有任何保护作用，而威廉姆斯分离系L78-379中的SMV抗性基因Rsv 1和小种子系L97-946中的抗性基因对SMV引起的斑驳具有高水平的保护作用。2000年和2001年亲本病毒感染与种皮斑驳相关系数分别为0.77和0.89，均达到极显著水平（P = 0.01），表明病毒感染是引起种皮斑驳的主要原因。
Soybean seed coat mottling often has been a problematic symptom for soybean growers and the soybean industry. The percentages of seed in eight soybean lines with seed coat mottling were evaluated at harvest after inoculating plants during the growing season with Bean pod mottle virus (BPMV), Soybean mosaic virus (SMV), and both viruses inside an insect-proof cage in the field. Results from experiments conducted over 2 years indicated that plants infected with BPMV and SMV, alone or in combination, produced seed coat mottling, whereas noninoculated plants produced little or no mottled seed. BPMV and SMV inoculated on the same plants did not always result in higher percentages of mottled seed compared with BPMV or SMV alone. There was significant virus, line, and virus-line interaction for seed coat mottling. The non-seed-coat-mottling gene (Im) in Williams isoline L77-5632 provided limited, if any, protection against mottling caused by SMV and none against BPMV. The Peanut mottle virus resistance gene Rpv1 in Williams isoline L85-2308 did not give any protection against mottling caused by SMV, whereas the SMV resistance gene Rsv1 in Williams isoline L78-379 and the resistance gene or genes in the small-seeded line L97-946 gave high levels of protection against mottling caused by SMV. The correlations (r = 0.77 for year 2000 and r = 0.89 for year 2001) between virus infection of the parent plant and seed coat mottling were significant (P = 0.01), indicating that virus infection of plants caused seed coat mottling.
