Composition of Glyphosate-Tolerant Soybeans

Research was conducted to determine if the composition of glyphosate-tolerant soybeans was equivalent to conventional soybeans when grown over several years and when the trait was introduced into several different genetic backgrounds. Soybean seed samples were collected from the 2000, 2001 and 2002 crops and analyzed for protein, oil, fiber, ash, lectins, trypsin inhibitors and isoflavones. These compounds represent the nutritional and bioactive components of soybeans. Results indicated natural variability for the glyphosate-tolerant and conventional soybean lines. The researchers concluded that the composition of glyphosate-tolerant soybeans over three years of breeding into multiple varieties remains equivalent to that of commercial soybeans.
