进入21世纪的10年间,受密植和国外品种的冲击和影响,我国玉米育种进入了新的发展时期。人口持续增长要求不断地提高玉米生产能力,多元化用途也要求有更多优质专用的玉米满足人们的需求,为增加农民收入和提升农业的国际竞争能力要求不断地提高育种水平。同时,生命科学的发展对玉米育种产生了深远的影响,分子标记和转基因技术在育种中得到广泛应用,高新技
In the 10 years of the 21st century, due to the impact and influence of close planting and foreign varieties, China’s maize breeding has entered a new period of development. Continued population growth requires continuous improvement of corn production capacity. The diversified use of corn also requires more high-quality and dedicated corn to meet people’s needs, and constantly raising the level of breeding in order to increase farmers’ income and enhance the international competitiveness of agriculture. At the same time, the development of life science has a far-reaching impact on maize breeding. Molecular markers and transgenic technology are widely used in breeding. High-tech
