Abstract:

Maize is one of the most important grain crops in China and plays an important role in the national economy. The transgenic technology has provided new method for breeding new maize varieties. The transgenic maize germplasm creation and its variety breeding involve many links including backcross breeding, molecular detection, object trait identification, transgenic bio-safety evaluation and new transgenic maize variety examination and approval, etc. This paper briefly expounded and discussed about the above technological links, and prospected the future of transgenic maize breeding.

Key words: transgenic, maize, new germplasm, backcross breeding

摘要：

玉米是我国最重要的粮食作物之一,在我国国民经济中占有重要的地位。转基因技术为玉米新品种培育提供了新的手段。转基因玉米新种质创制及品种培育涉及回交转育、分子检测、目标性状鉴定筛选、转基因生物安全评价试验、转基因玉米新品种的审定等诸多环节,就以上环节进行了简要阐述与研讨,并展望了今后转基因玉米育种的前景。
