| 摘 要： | 以14个春小麦品种为试材,对旗叶性状与产量及产量性状作了相关与多元回归分析。结果表明,测试小麦旗叶长、旗叶宽、叶面积、旗叶与茎秆的夹角与穗粒数、千粒重、株穗数和产量等性状间的相关系数分别达显著或极显著,建立了旗叶性状与产量及产量因素的最优多元回归方程。

| Abstract: | Correlation and regression of flag leaf traits and yield traits were studied using 14 varieties of spring wheat.The experimental results showed that the flag leaf length,flag leaf width,flag leaf area and chlorophyll content of flag leaf were positively related to grain number per spike,1000-grain weight,grain weight per spike and grain yield.The angle between flag leaf and stem were related negatively with grain yield.The multiple regression equations between flag leaf traits and yield characters were foun... |
