Interpretive Summary: Host-plant resistance is potentially efficacious in managing the soybean aphid (SA), a major invasive pest in northern soybean-production regions of North America. However, development of aphid-resistant soybean has been complicated by the presence of resistance-breaking SA biotypes, and thus a variety of unique resistance sources are needed to counter the biotypes. This study identified 14 putatively resistant sources out of 746 Plant Introduction (PI) lines screened against avirulent SA biotype 1. Follow-up no-choice tests with 11 of the 14 PI lines validated SA resistance in three of them. These three lines should be advanced for testing against virulent SA biotypes to determine their usefulness in efforts to breed aphid-resistant soybean.

Technical Abstract: Host-plant resistance is potentially efficacious in managing the soybean aphid (SA, Aphis glycines Matsumura), a major invasive pest in northern soybean-production regions of North America. However, development of aphid-resistant soybean has been complicated by the presence of virulent SA biotypes, and thus a variety of unique resistance sources are needed to counter the array of virulent biotypes. This study identified 14 putatively resistant sources out of 746 Plant Introduction (PI) lines screened against avirulent SA biotype 1. Follow-up no-choice tests with 11 of the 14 PI lines validated SA resistance in three of them. These three lines should be advanced for testing against virulent SA biotypes to determine their usefulness in efforts to breed aphid-resistant soybean.
