Abstract

Host plant resistance for soybean aphid is the newest management tool for farmers. In 2010, a single gene expression, called Rag1, was commercially released in the North Central Region. Aphids feeding on Rag1 plants do not live as long or produce as many offspring compared to feeding on susceptible plants. In small plot evaluations of the Rag1 gene, there is a dramatic decrease in the seasonal accumulation of soybean aphid compared to susceptible varieties.
