| 摘 要： | 选取18个冬小麦品种，设浇灌和非浇灌两种处理，用相关和通径分析法，研究其产量形成特点，结果表明：产量性状与产量在相关程度上，以及产量性状对产量的作用大小上有一定差异，穗粒数，穗粒重和株高与产量相关显著，而千粒重与产量相关不显著，产量构成中穗数、穗粒重的作用较大。

| Abstract: | The 18 characteristics of yield formation of in winter wheat were analyzed by the aid of correlation and path analysis methods under irrigated and non irrigation conditions. The results indicated that both the correlation between yield and yield components, and the contribution value of yield components to yield were different. There was positive correlation between yield and grain number per spike, grain weight per spike and plant height, while there was non correlation between yield and 1000 kernel weight. The characteristics of spike number per plant and grain weight per spike played greater contribution to yield. |
