Abstract

The purpose of this test was to evaluate the experimental food-type soybean lines adapted for northern Iowa. The 2004 specialty test included soybean cystnematode (SCN)–large seed, large seed high protein, small seed, and lipoxygenase-free experimental lines, and for comparison of agronomic traits, commercially grown SCN-resistant varieties released by Iowa State University. Large seed, large seed high protein, small seed, and lipoxygenase-free soybean varieties grown in Iowa are used to fill a niche in the food-bean market. These soybeans are mainly exported to Japan. Large seed soybeans are used in the production of miso, a soy product used to make soup, and are consumed as a vegetable. Large seed high protein soybeans are used for tofu production. Small-seed soybeans are used to create natto, a Japanese breakfast food. Lipoxygenase-free soybeans have less of the “beany” flavor associated with conventional varieties. This flavor trait is desirable in producing soy-based foods like soy milk.
