| 摘 要： | 通过调查测定胡麻13个品系的单株产量及与其相关的主要农艺性状——株高（x1）、工艺长度（X2）、分茎数（X3）、分枝数（X4）、单株果球数（X5）、每果粒数（X6）及单株粒重（Y）7个性状，应用逐个选入自变数的回归方法，得到13个最优多元线形回归方程，再对入选的几个主要性状进行通径分析，明确了提高胡麻单株产量．首先要具有一定的单株果球数、株高和每果粒数。其次，不同的品系对单株粒重起关键作用的性状不同。

| Abstract: | After investigating kernel weight per plant and their correlation of six agronomic characters (Height,Stem number, Fabric length,Ball number,Seed number per ball and Kernel weight per plant) of thirteen linseed lines,the regression method was used to select the variable by every step,and then got thirteen linear regression equations.Different linseed lines had different characters that had been chosen to take path analysis during the choosing steps.And that indicated their relationship and contribution to y... |
