Soybean aphid（Aphis glycines Matsumura） is one of the most harmful pest insect in the world. It is practical way to control soybean aphids by using the aphid resistant plants. The aphid resistance of the five aphid resistance plants PI567543 C, PI567541 B, PI567598 B, ML2008 and A32-2, which were introduced from USA, was tested in net house at Gongzhuling, Jilin Province. The results showed that PI567541, ML2008 and A32-2 were susceptible. PI567543 C and PI567598 B were resistant to soybean aphid and they can be used in aphid resistant soybean breeding. PI567543 C was the most resistant, and its resistance was better than W85-32, a wild aphid resistant material in China.
