Abstract: As a major grain producing province, Jilin province is the main force to support national food security. Maize is the core industry to ensure the increase of grain yield in Jilin province, while increasing yield per unit area was an inevitable way for insure food security in the future. On the basis of combing the development process of maize yield in Jilin province since the founding of the Peoples Republic of China, this study analyzed the scientific and technological contribution of new varieties for the improvement of maize yield in Jilin province, and made a comparative analysis of maize yield between Jilin province and other provinces abroad. The problems restricting the promotion of maize yield in Jilin province were pointed out. In order to further improve the yield per unit of maize in Jilin province, we should carry out the protection and evaluation work of maize germplasm, strengthen the expansion and improvement of germplasm, carry out basic research on regional maize application, break through key core breeding technology, accelerate intelligent and accurate breeding of major independent new varieties, and innovate green and high yield production technology of black land, which should be benefit for promotion of maize production capacity, take the lead in realizing agricultural modernization, and provide the basis for ensuring national food security.

摘要： 吉林省作为粮食主产省，是扛稳国家粮食安全重任的主力军。玉米是保障吉林省粮食安全的核心，而提升单产水平是玉米增产的必然途径。在梳理建国以来吉林省玉米单产发展历程的基础上，分析了良种对单产提升的贡献，并对吉林省玉米单产与国内外进行对比分析，指出了当前制约吉林省玉米单产提升的主要问题。为进一步提升吉林省玉米单产，提出应扎实开展种质资源保护鉴定评价工作、强化种质扩增改良、开展区域性玉米应用基础研究、突破关键核心育种技术、加快重大自主新品种智能化精准选育、创新黑土地绿色丰产生产技术等发展建议，为加快提升玉米产能、率先实现农业现代化、确保国家粮食安全提供了依据。
