一套功能健全的商业育种技术体系是商业育种研发流水线的保障。新世纪伊始,各种玉米育种新技术层出不穷,例如分子标记辅助选择技术、单倍体育种技术、品种精确评价技术和高通量数据采集技术等,这些技术大大提高了商业育种研发流水线的效率。本文从我国玉米种业的研发现状出发,分析育种新技术在加速商业育种进步中的作用,提出切实可行的玉米种质资源创新体系,该体系整合了包括分子标记辅助选择技术、单倍体育种技术、品种精确评价技术、高通量数据采集技术和育种大数据管理技术在内的先进商业育种技术,构建了玉米规模化种质资源创新体系,可以更有效地加速我国玉米商业育种的进程。

Since new millennium, a number of new breeding technologies had been emerged or advanced, such as marker assistant selection, haploid doubling technology, evaluation and positioning of hybrids, high throughput phenotyping technology etc. These technologies had dramatically improved the efficiency of plant breeding. A well-organized technology pipeline was essential to the success of a commercial breeding institution. In this paper, the current status of commercial breeding in China and the importance of several breeding technologies were reviewed, and a practical breeding technology system for maize germplasm improvement was provided. The system integrated marker assistant selection, haploid doubling technology, precision evaluation and positioning of hybrids, high throughput phenotyping and breeding big data management, it could more effectively accelerate maize commercial breeding process of China.
