玉米孤雌生殖单倍体诱导及加倍机理研究新进展

Research Progress in the Mechanism of Parthenogenesis Haploid Induction and Doubling on Maize

玉米单倍体技术的应用可以大大缩短自交系选育年限,加快育种进程,提高选育效率,尤其是孤雌生殖单倍体技术的广泛应用,能够在高效加倍的基础上快速选育稳定的纯系。本文较全面地综述了近年来关于玉米孤雌生殖诱导产生单倍体的机理及单倍体染色体加倍分子机制的研究新进展,旨在为单倍体技术更广泛的应用提供一定的理论依据。

Application of haploid technology can significantly shorten breeding time,accelerate the breeding process and improve the breeding efficiency,especially the parthenogenesis haploid induction technology,which is widely applied to quickly provide stable pure line based on the haploid doubling efficiency. In this paper,the new research progress in the mechanism of parthenogenesis haploid induction and chromosome doubling on maize was reviewed. It would help our further understanding of the theoretical basis and broaden the utilization of maize haploid.
