| 摘 要： | 根据25个蓖麻杂交种15个主要数量性状的测定结果，应用逐个选入显著自变数的逐步回归方法，得到包括门桩穗长、一级分柱粒重、单株粒数在内的最优多元线性回归方程，再对入选的3个主要性状进行通径分析。结果表明，要提高蓖麻单株产量，首先要从提高一级分枝粒重着手，其次是从提高单株粒数着手，再次是使门桩穗长适当。 |

| Abstract: | The optimal linear regression equation of multi components (including ear length of primary branches?seed weight of primary branches?number of seeds per plant )was obtained with the stepwise decomposition method of independent variable,based on the determination of 15 main quantitative characters in the 25 hybrids of castor.The further path analysis of 3 selected characters exposes the way to increase the product of each plant of castor. |
