玉米单倍体育种技术能显著加快育种进程。单倍体高效率加倍是单倍体技术能否广泛应用于育种实践的关键因素。综述了单倍体加倍的主要方法,介绍常用的秋水仙素化学加倍技术,对其他细胞分裂抑制剂也做了简要介绍,并对今后的单倍体加倍研究进行了展望。 Maize haploid breeding technology can significantly speed up the breeding process. Doubled haploidentical efficiency is a key factor in whether haploid technology can be widely applied in breeding practice. The main methods of haploid doubling are reviewed. The commonly used colchicine chemical doubling technique is introduced, other cell division inhibitors are briefly introduced, and the prospect of haploid doubling research in the future is also prospected.
