| 摘 要： | 本文应用相关和通经系数分析方法，对两种杂交组合方式的小麦F1代农艺性状进行研究。结果表明，春小麦品种间杂交组合F1代的穗粒数多于春、冬小麦杂种F1代的穗粒数；两种杂交方式的F1代单穗粒数与单穗粒重的关系极为密切，对其单穗粒重的贡献最大。为春小麦优质高产育种提供科学途径。

| Abstract: | The paper studies main agricultural characteristics of F1 in two patterns of crossing combination by methods of coefficient correlation and path analysis. The results indicated that F1 grain number of per spike of crossing combination in the spring wheat X spring wheat is more than F1 in the spring wheat X winter wheat, and F1 grain number of per spike shows extremely positive relation with grain weight of ear and it greatly contributes to grain weight of ear. For this reason, it provide scientific way in order to breed variety with good quality and high yield in the spring wheat. |
