Evaluation of Aphid-Resistant Soybean

Authors: , ,


The soybean aphid (Aphis glycines Hemiptera: Aphididae) is the most economically important insect pest of soybean in the north central region of the United States. Using varieties with native aphid resistance genes (Rag) can effectively suppress aphid populations and can replace insecticides. Furthermore, a pyramid of two or more Rag genes within the same variety offers better yield protection than a single Rag gene. Although this tool is highly effective, Rag varieties are not widely used by soybean producers, partly because of their limited availability. Soybeans with and without aphid resistance as a means to combat soybean aphid outbreaks were evaluated.
