摘  要：
With the increase of people's living standard,maize varieties of high yield,anti-adversity,high quality and disease resistance have been urgently needed. Maize breeding efficiency has increased significantly by the rapid development and wide application of biotechnology. The combination of conventional breeding method with biotechnology has not only offered a new way of maize breeding but also speeded up its progress. On this basis,kinds and characteristics of genetic engineering technology and molecular marker technology were analyzed,application of genetic engineering technology in stress tolerance,insect resistance,herbicide resistance and quality improvement and molecular marker technology in gene mapping,genetic diversity analysis,division of heterosis group,purity identification and marker-assisted selection were introduced in this paper. Application prospects of genetic engineering technology and molecular marker technology in maize breeding were expected,and importance of the combination of biotechnology with conventional maize breeding was summarized as well.
