Interpretive Summary:

Technical Abstract: The research to develop soybean cyst nematode (SCN), Heterodera glycines, resistant soybeans at the University of Illinois began in the 1970's. Initially, the research was a USDA, ARS effort with greenhouse evaluations done at Portageville, Missouri. G. R. Noel was transferred by the USDA to Urbana in 1978 and the University of Illinois hired C. D. Nickell in 1979 to complement the program and to maintain the continuity of the soybean breeding effort upon the retirement of R. L. Bernard (former USDA breeder). Cooperative effort between the soybean breeding programs and the USDA nematology program at the University of Illinois has resulted in the release of 17 SCN-resistant varieties and four SCN resistant germplasm lines. The releases have ranged from maturity Group IV to maturity Group I and have utilized resistant germplasm from the plant introductions (PI), PI88.788, PI89.772, PI90.763, PI209.332, and PI437.654 and the varieties `Cloud' and `Peking'. The value of these releases to soybean producers has been in the hundreds of millions of dollars as evidenced by production of certified seed by the Illinois Crop Improvement Association. For example in 1996, 46% of the certified seed acreage in Illinois was planted to varieties developed by the program. The variety `Fayette', which was released in 1981, has been the most widely used source of resistance in both public and private breeding programs in the midwest. The year of release, maturity group, source of resistance, and reaction to various races of SCN of each variety and germplasm line are provided.
