| 摘 要： | 为了较好地发展山西省的玉米生产，根据省内复杂的地形和多变的气候，分为不同的种植区域。对参加区试的各区域中增产的品种或增产前5名品种的生育期、株高、穗位高、穗长、穗粗、秃尖长、穗行数、行粒数、百粒重和出籽率等与产量密切相关的性状进行了相关关系的研究。结果表明：各区域中玉米的特征特性与产量的相关关系不同。只有针对不同区域玉米对株高、穗位高、穗长、行粒数和百粒重等特征特性要求的不同，进行差异化品种选育，才能有效提高本区域农业资源的利用效率，从而提高玉米单位面积的产量。

| Abstract: | In order to better develop maize production in Shanxi, the author divided the whole province area into different planting areas according to the complex topography and changeful climate. The author studied the correlations between growth period, plant height, ear height, ear length, ear thickness, bald tip length, rows of each ear, grain number per row, hundred-grain weight, rate of seed and yield of varieties which had yield growth or the yield growth listed as top 5 in each testing area. The results showed that the correlations between the characteristics and yield were not the same in the different areas. It could effectively improve the utilization of agricultural resources and raise the yield per unit area to breed different varieties according to different requirements of corn characteristics in different ecological areas. |
