Evaluation of Soybeans Resistant to Heterodera glycines Race 5 for Yield and Nematode Reproduction

Two soybean breeding lines (D82-2397A and J82-190) resistant to Heterodera glycines race 5 produced higher yields (P = 0.05) than the race 4-resistant cultivar Bedford for 2 years when planted in a field infested with H. glycines race 5 at Tiptonville, Tennessee. Yields were not different between D82-2397A and Bedford when planted in fields infested with race 3, race 9, or with no cyst nematodes. D82-2397A will be released as a cultivar in 1988.
