| 摘 要： | 本文用简单相关,通径系数,逐步回归等分析方法,对45个大粒品种的八个性状进行了统计分析,结果表明:千粒重受多因素影响,其中穗粒数,穗长对粒重的直接影响为负值,穗下节长,旗叶宽对粒重的直接影响为正值。株高对粒重的直接影响不显著,但可通过其它因素影响粒重。

| Abstract: | Eight characters of 45 big-kernel wheat varieties were analysed usingsimple correlation,path-coefficient and stepwise regression.The mainresults were as follows:many factors affected kernel weight;the directeffects of kernel/spike and length of spike on kernel weight were nega-tive,while the peduncl |
