Abstract
The physical strength of stalk is tested in the peak time of wheat filling, while correlation analysis and multiple regression analysis on properties such as the length, width and plant height of each stalk and the biological yields were carried out The results revealed: The correlation between physical strength of stalk and its internode length were negative correlation, the correlation with the first,second knob of the caudex were significant, with the third knob of the caudex was very significant, with the fourth node of the middle stalk was very significant The correlation between the physical strength and spike length and weight were insignificant The correlation between the physical strength and the second, third and fourth node width were very significant The quality of dry substance in the second knob of caudex contributed most to the physical strength The selection of short-stalk, strong-stalk and big- spike variety is feasible for the variety breeding of wheat lodging resistance
