In 1997, about 8% of all soybeans cultivated for the commercial market in the United States were genetically modified. In 2010, the figure was 93%.National Agricultural Statistics Board annual report, June 30, 2010. Retrieved July 23, 2010. As with other glyphosate-tolerant crops, concern is expressed over damage to biodiversity. A 2003 study concluded the "Roundup Ready" (RR) gene had been bred into so many different soybean cultivars, there had been little decline in genetic diversity, but "diversity was limited among elite lines from some companies".
