鉴于世界人口的急剧增长,对农业生产提出的更高要求,科学家都在努力探寻和培育新的更高产的农作物。在过去一个世纪里,人们为这一目的而进行的全球性植物资源探索,并没有发现任何新的理想的农作物。企图用一个新兴作物去代替现在世界上广泛栽培的水稻、小麦、玉米等主要农作物已经毫无希望。但科学家发现,要改进和培育水稻、小麦、玉米等农作物品种和提高产量不但有可能,还有很大的潜力。为了使玉米产量更高、 In view of the dramatic increase in the world’s population and the higher demands placed on agricultural production, scientists are trying to find and cultivate new and more productive crops. In the past century, the exploration of global plant resources for this purpose has not found any new ideal crops. There has been no hope of replacing the major crops such as rice, wheat and corn widely cultivated in the world today with an emerging crop. However, scientists have found that it is not only possible but also potentially significant to improve and nurture crop varieties such as rice, wheat and maize and to increase yields. In order to make corn more productive,
