转基因技术是1995年引入大田作物的,到1997年全球种植规模发展到1100万公顷,1998年已达2800万公顷,预计2003年可达8400万公顷。1999年,美国的2900万公顷大豆中,有一半用上了经转基因工程制得的耐除草剂品种,3200万公顷玉米和520万公顷棉花中,转基因品种也占了相当大的比例;加拿大的油菜,转基因品种已超过一半,1998年全世界的转基因种子销售额为15亿美元,占农用化学品销售额300亿美元的5％,预计2000年和2010年将分别达到30亿美元和250亿美元。
Transgenic technology introduced field crops in 1995 and by 1997 the global scale of planting had grown to 11 million hectares. In 1998, it reached 28 million hectares and is expected to reach 84 million hectares in 2003. In 1999, half of the 29 million hectares of soybeans in the United States used genetically engineered herbicide-tolerant cultivars, 32 million hectares of corn and 5.2 million hectares of cotton, and genetically modified varieties also accounted for a considerable proportion. Canada More than half of the canola and GM varieties have been sold. In 1998, the sales of genetically modified seeds worldwide reached 1.5 billion USD, accounting for 5% of the sales of agrochemicals. It is estimated that in 2000 and 2010, it will reach 3 billion USD and 25 billion respectively Dollars.
