In 2003, there was a new record of the proportion of GM crops grown in the United States. The area of GM cotton, corn and soybean was higher than the forecast in the USDA3 survey. June crop area estimates indicate that 81% of U.S. soybeans have been planted with GM lines, estimated at 80% in March and 75% in 2002. Of this year’s highland cotton area, 73% of GM varieties have been planted, estimated at 70% in March and 71% in 2002. This year, 40% of the corn area is planted with GM varieties, which is expected to be 38% in March and 34% last year. GM herbicide-tolerant soybeans rose 8% to 59.7 million acres (24.2 million hectares), rising in 14 major soy-producing states. Every state, grow GM
