Abstract: Scientific and technical support to Xinjiang is one of important strategic decisions in China. In order to promote development of the Maize research and to explore the experience of introduction and high yield in Xinjiang, and to improve the economic efficiency of maize, the introduction test of new maize varieties in Xinjiang was carried out from Maize Research Institute of Shanxi Academy of Agricultural Sciences since 2013. Through the introduction of 42 maize varieties bred in Shanxi in recent years, the experiment was conducted by the field fine management and setting up the arrangement of the control. And the investigation of biological, agronomic and yield traits was carried out. From the test results, it can be know that there were effect on plant height, ear height, growth period along with environment change and density increased, film mulching cultivation. And most species can not adapt to the climate in Xinjiang, but there are still some varieties of moderate growth period, excellent agronomic characters, excellent resistance, yield more than that of the control. It can be seen that Shanxi bred varieties has better adaptability of Xinjiang Climate and cultivation mode that can be screened using. Therefore, we thought if the spring-sowing maize varieties bred in Shangxi should be popularized in Xinjiang, they must have these characteristics including high yield, enduring high-density planting, moderate growth period, strong lodging resistance and suitable for mechanical operation.
