小麦在全世界范围来说都是一种大规模种植的作物。1995年到1997年之间,每年世界范围内小麦种植地超过22.5亿公顷,小麦年产量为56亿吨,占全世界谷类食品产量的四分之一以上。小麦虽是很多发达国家和发展中国家人民的主食,然而它的营养价值却不如大豆和玉米高,而且在遗传技术上很难进行改造,所以直到最近它才成为生物技术及该行业的科学家关注的焦点。 Wheat is a large-scale crop all over the world. Between 1995 and 1997, more than 2.25 billion hectares of wheat are planted worldwide each year, with an annual output of 5.6 billion tons of wheat, accounting for more than a quarter of the world’s cereal production. Although wheat is the staple food of many people in both developed and developing countries, its nutritional value is not as high as that of soybeans and maize and is difficult to transform genetically, and until recently it became a concern for biotech and its scientists in the industry Focus.
