| Abstract: | Objective]The aim was to research on construction of yield formation model of winter wheat.Method]In the case of variety Shijiazhuang 8,the process of yield trait formation was studied by the dynamic ideal and uniform experimental design;the differences between plant dry weight and population indexes were analyzed by using multiple comparison analysis,and the yield formation model was developed by multiple regression analysis.Result]The results showed that multiple correlation coefficients of yield formation model ranged from 0.91 to 0.97.Conclusion]The model was significant which provide certain theoretical base for high yield and high efficiency cultivation of winter wheat. |
