| 摘 要： | 试验运用灰色关联度分析方法,研究5个不同热带玉米种质穗部性状对单株产量的贡献大小。结果表明:种质T9904的百粒重与单株产量关联度大,对单株产量贡献大;种质T9907、T9925、T9945和T9963的穗行数与单株产量关联度大,对单株产量的提高起着重要的作用。种质T9904和T9945的百粒重和穗行数对单株产量的贡献作用相差较小。

| Abstract: | The grey related degree analysis was employed to study the effect of ear characters on yield per plant of 5 tropical maize germplasm.The study indicated that the grey related degree between the 100-kernels weight and yield per plant of T9904 was higher,so 100-kernel weight was the main contributing factor to T9904 yield per plant.Differently the grey related degree between the row number of ear and yield per plant of T9907,T9925,T9945 and T9963 was higher,so the row number of ear was the main affecting factor to yield per plant.The contribution of the 100-kernels weight and the row number of ear to yield per plant was basically same in T9904 and T9945 |
