| 摘 要： | 在不同生态区种植同一基础材料诱导产生的单倍体，研究种植环境对单倍体自然加倍率的影响。结果表明，不同地区的玉米单倍体自然加倍率差异显著，在张掖和三亚单倍体自然加倍率相对较高，分别为5.4%和4.8%，在陇南的自然加倍率最低为1.6%，说明在张掖春播和三亚冬播更适合玉米单倍体自然加倍。

| Abstract: | The corn haploid induced from the same basic material is used to study natural doubling rate in the different ecological areas planting. The result shows that have significant difference about natural doubling rate in the different ecological areas planting. Natural doubling rate is relatively high in Zhangye and Sanya, 5.4% and 4.8%, respectively. However, it is relatively low of 1.6% in Longnan. The result reveals that spring sowing in Zhangye and Winter sowing in Sanya are more suitable for natural doubling of corn haploid. |
