| 摘 要： | 从春小麦选育的角度探讨了春小麦的边际效应指数，并研究了春小麦的产量边际效应指数与其穗部各性状边际效应指数之间的关系。研究结果表明，边际效应指数可以作为选择耐密型春小麦品种的指标，株穗数、主穗小穗数，主穗粒数等性状的边际效应指数与产量边际效应指数呈显著或极显著正相关，穗长的边了示效应指数与产量的边际效应指数正向相关不显著。

| Abstract: | The results showed that the margiral effect index was considered an indicator of improving spring wheat varieties with tolerant to solid-planted. The margiral effect index of yield was significantly or very significantly correlated to that of the spike numbers of a plant, spikelet numbers of the main ear, etc. The margiral effect index of spike length was not significantly correlated to that of the yield. |
