　　为探讨有利于玉米单倍体自然加倍的环境条件和基因型材料，为单倍体育种提供参考，利用玉米孤雌生殖诱导系农大高诱1号和5份不同基因型材料诱导产生的玉米单倍体，分别在石家庄春播、石家庄夏播和三亚冬播，在3种生态环境条件下开展玉米单倍体自然加倍效果的研究。结果表明：不同基因型材料间、不同环境条件下，玉米单倍体自然加倍效果差异明显，其中，三亚冬播效果最好，石家庄春播次之，石家庄夏播不适合单倍体自然加倍；参试基因型材料中，先玉808、 MSD1和DMY1的自然加倍效果较好。

In order to explore the environmental conditions and genotypes suitable for natural doubling of maize haploid, provide the reference for the haploid breeding.Using induced haploid Nongda Gaoyou No.1 and 5 different genotypes induced haploid grains as the materials, which were planted in spring of Shijiazhuang, summer of Shijiazhuang and winter of Sanya, the natural doubling effect of maize haploid in different ecological environments were studied.The results showed that the natural doubling effects of different genotypes materials and the different environments had significant differences, the natural doubling effect in winter of Sanya was best, in spring of Shijiazhuang was followed and in summer of Shijiazhuang was not suitable for haploid natural doubling.Among the tested genotypes, the natural doubling effects of Xianyu 808、 MSD1 and DMY1 were better.
