Abstract: The aims are to analyze wheat yield potential in the northern winter wheat region of China, and to find out the limiting factors and explore the corresponding control techniques for improving wheat productivity. The yield and high yield record of winter wheat simulated by the native-area model was summarized. The differences between model simulation and high yield record were compared and analyzed. This study summarized the main reasons which limited yield gap reducing and the possible control techniques. It was concluded that the simulation results of the current model were lower than that of the high yield records because of the influence of the data collection year and the amount of data. Yield performance theory was an effective method for quantitative analysis of yield-gap causes. It was pointed out that the main reasons limiting yield gap reducing and control techniques in the northern winter wheat region of China. It is suggested that the improvement of wheat yield should be carried out in three aspects: determining yield gap, yield performance analysis and integrated technology.
