在今后的几十年,我国玉米需求面临巨大的压力,育种目标的核心是继续提高杂交种的生产潜力和利用价值。但品种资源的狭窄制约我国生产水平的提高。因此为了实现玉米生产的可持续以展,拓宽品种资源,加强对种质的改良、扩增、创新是当务之急。玉米种质产业的发展要在种质扩增、改善品质和应用生物技术领域取得突破性进展。 In the coming decades, the demand for maize in our country is under tremendous pressure. The core of the breeding goal is to continue to increase the production potential and value of hybrids. However, the narrow varieties and resources restrict the improvement of China’s production level. Therefore, in order to achieve sustainable development of corn production, broaden the variety of resources, and strengthen the improvement, expansion and innovation of germplasm, it is imperative. The development of maize germplasm industry has made breakthrough progress in germplasm expansion, quality improvement and applied biotechnology.
