据统计,近十几年来,玉米产量增加的诸因素中,遗传改良因素占35%左右,化肥因素占51%左右,其它因素占14%左右,说明玉米育种在生产中发挥着重要作用。美国玉米专家也提出,美国玉米产量不断提高的历史就是玉米育种发展的历史,也同样说明了这个道理。当前面对人世的挑战,民族种业怎样与国外诸强抗衡,中国这一世界第二大玉米市场,将拥有多大的席位,是我们从事玉米工作的人员应该思考的问题。 1 育种队伍
According to statistics, in the past ten years, among the factors that increase corn yield, 35% are genetic improvement factors, about 51% are fertilizer factors and about 14% are other factors, indicating that maize breeding plays an important role in the production. American corn experts also pointed out that the history of the continuous improvement of corn production in the United States is the history of the development of corn breeding, which also illustrates this truth. At present, in the face of the challenges posed by the worldly life, how ethnic ethnic industries compete with foreign superpower and the number of seats China will have in the world’s second largest corn market are the issues that should be considered by the personnel engaged in corn work. 1 breeding team
