| 摘 要： | 回归分析表明,高产杂交油菜的产量与主轴结角数、一次分枝结角数、二次分枝结角数、角果长度、每角粒数和千粒重间存在极显著的线性关系。通径分析结果表明,一次分枝结角数、二次分枝结角数和每角粒数是高产杂交油菜最重要的构成因素。各因素间存在着交互作用,且这些交互作用对产量有重要影响。

| Abstract: | Regression analysis shows that there are significant linear relationships between the yield and number of siliqua on main axis,number of siliqua on primary branch,number of siliqua on secondary branch,siliqua length,seeds per siliqua,1000-seed weight of high-yielding hybrid rapeseed.Path analysis shows that number of siliqua on primary branch,number of siliqua on secondary branch and seeds per siliqua are the important yield components for rape.There are many interactions among various yield components,and ... |
